August 2002 Revision 2.2 Geode™ CS1301/CS1311 Multimedia Companion: Media Coprocessor General Description The National Semiconductor® Geode™ CS1301 and CS1311 multimedia companions act as coprocessors to decode multimedia in National’s Geode single chip processor-based systems (i.e., SC1200/SC1201, SC2200, and SC3200, hereafter referred to as SCx200). They provide a multimedia experience for an Information Appliance (IA) user that cannot typically be achieved on a PC. coprocessor’s task of decoding media and thereby causing stuttering of sound or interruptions in the video. Lower power consumption can also be achieved using the SCx200/CS1301 or SCx200/CS1311 solution. The CS1301/CS1311 has an architecture specifically designed for decoding media. The architecture is such that while decoding media, power is not consumed by portions of the system that are not used to decode media. Since the SCx200 is not decoding the media locally, it is able to go into a lower power state. When the CS1301/CS1311 is not decoding media, it uses almost no power. By implementing a dedicated coprocessor to perform multimedia tasks, a high quality video viewing experience can be achieved. This high quality is achieved by having a coprocessor architecture that is ideally suited for decoding digital media. In addition, since the decoding is not occurring on the SCx200, system events cannot interrupt the Additionally, since the architecture is designed for decoding media, fewer CS1301/CS1311 cycles are required.

Figure 1-1 provides a typical system block diagram. 1.1 IMPORTANT DESIGN NOTE The CS1301/CS1311 was designed to be a general purpose media data processor. As such, the CS1301/CS1311 is capable of far more than the current National CS1301/CS1311 solution. The solution that National is providing is only one possible implementation of the CS1301/CS1311 and only this implementation is fully supported by National Semiconductor. In order to maintain software compatibility with National’s provided software, any deviation of the CS1301/CS1311 section of the schematic is strongly discouraged. Media decoding is one of the most demanding system applications. If media is decoded on the main processor, a much higher performance processor is required to achieve even comparable levels of media decoding quality. Such a system would be significantly over-designed for other tasks, such as browsing the Internet. Using a low-cost processor that is ideally suited for all tasks, and adding the coprocessor for the high performance media decoding requirement, results in a cost-effective solution. For those wishing to deviate from the schematic, or wishing to take advantage of other features of the CS1301/CS1311, documentation is available on the Philips Semiconductors SDE CD-ROM to support design variations. However, additional support to implement these variations must be obtained from one of the TriMedia Alliance Partners who support the CS1301/CS1311, its software, and the peripheral functions. Another advantage of an processor/coprocessor solution is that an OEM (Original Equipment Manufacturer) can provide a scalable solution. A single board can be designed that supports the coprocessor. If it is desired to support a low-end product that does not support the high quality media decoding capabilities, the coprocessor and its supporting components can be excluded from the system, which results in additional savings in an already cost-effective design.

As part of the CS1301/CS1311 purchase (see Section A.1 "Ordering Information" on page 24 for purchase details), National will license for the use of the operating system drivers and media decoder codecs in object form, which include: MPEG-2 Decoding • Communications manager driver. • Audio stream - MPEG-2 audio: — Layers 1 and 2 (ISO 13818-3) at 32 KHz, 44.1 KHz or 48 KHz sample rate — AC3 audio at 32 KHz, 44.1 KHz or 48 KHz sample rate • Program stream (ISO 13818-1): DVD style MPEG-2 program stream • Video stream (ISO 13818-2) - Main level at main profile: — Full screen NTSC (720x480) at 29.97 fps — Full screen PAL (720x576) at 25 fps • Video filter: Takes the video from the VIP (Video Input Port) of the Geode SCx200 and plays it back through the operating system media player. • Various multimedia codecs. MPEG-1, MPEG-2 Layer 3 Audio Decoding (MP3) 1.2.1 Software Support National provides a reference schematic and the associated software for a processor/coprocessor solution using the Geode SCx200 and the CS1301/CS1311. This implementation is currently supplied as a multimedia decoder for CE player under Microsoft Windows CE.net or Linux. Future support for Microsoft Windows XP is planned. Since this is a software-based DSP (Digital Signal Processor) coprocessor rather than strictly a silicon-based coprocessor, the software can be upgraded to support evolving media standards without a redesign of the hardware. • Up to 384 Kbps • Up to 48 KHz sample rate • Fixed bit rate decoding MPEG-4 Decoding • Video stream - “Simple profile”: — CIF resolution at 30 fps, up to 384 Kbps • Audio stream - “High quality profile”: — MPEG-4 AAC low complexity and MPEG-4 CELP 1.2.2 Software Features Support The CS1301/CS1311 multimedia solution supports the following software components: WMT (Windows Media Technology) Decoding • Video stream - Windows Media Video v8, also supports v7 decode: — CIF resolution at 30 fps, up to 1 Mbps General Support • Reverse 3:2 pull down • Audio stream - Windows Media Audio v8, also supports v7 decode: — Up to 128 Kbps and 48 KHz sample rate • Progressive display output • Capture Video Input Windows Media Player Integration An implementation has been developed to seamlessly integrate Windows Media Player with WindowsCE.net or Linux. National has taken advantage of the native playback features supported by Microsoft DirectShow and has extended that functionality to the CS1301/CS1311. WindowsCE.net ships with an ActiveX control that wraps the filter graph manager and provides a very high level API (Application Programming Interface). It also supports a browser plug-in. An application writer can use the ActiveX control interface to playback MPEG-1/MPEG-2 media types. The user can also open the MPEG-1/MPEG-2/WMT files in Windows Media Player by double clicking on the file or by launching WMP, then opening the selected media. MPEG-1 Decoding • System stream (ISO 11172-1): — Up to 1.5 Mbps • Video stream (ISO 11172-2): — CIF (up to 360x288) resolution — 29.97 fps (NTSC) — 25 fps (PAL) — Up to 1.12 Mbps • Audio stream (ISO 11172-3): MPEG-1 layers 1 and 2: — Up to 384 Kbps, 32 KHz, 44.1 KHz or 48 KHz sample rate New codecs are continually being developed and added (see National’s IA Developer’s web site for a list of supported codecs). www.national.com 4 Revision 2.2 1.2.3 Software Architecture Overview Figure 1-2 demonstrates the interaction between the various software layers.

PCI_C/BE0# M3 I/O PCI_C/BE1# J3 Multiplexed Bus Commands and Byte-Enables. High for command, low for byte-enable. PCI_C/BE2# D2 Signal Name PCI_CLK PCI_AD[31:00] Description PCI Clock. All PCI input signals are sampled with respect to the rising edge of this clock. All PCI outputs are generated based on this clock. This clock is required for normal operation of the PCI module. PCI_C/BE3# B3 PCI_PAR H1 I/O Parity. Even parity across AD and C/BE# lines. PCI_FRAME# E2 I/O Frame Sustained TRI-STATE. Frame is driven by a master to indicate the beginning and duration of an access. PCI_IRDY# E1 I/O Initiator Ready Sustained TRI-STATE. Initiator Ready indicates that the bus master is ready to complete the current data phase. PCI_TRDY# F3 I/O Target Ready Sustained TRI-STATE. Target Ready indicates that the bus target is ready to complete the current data phase. PCI_STOP# G2 I/O Stop Sustained TRI-STATE. Indicates that the target is requesting that the master stop the current transaction. PCI_IDSEL A2 I PCI_DEVSEL# F1 I/O Device Select Sustained TRI-STATE. Indicates whether any device on the bus has been selected. PCI_REQ# B7 O Request. Driven by the CS1301/CS1311 as a PCI bus master to request use of the PCI bus. PCI_GNT# B5 I Grant. Indicates to the CS1301/CS1311 that access to the PCI bus has been granted. PCI_PERR# G1 I/O Parity Error Sustained TRI-STATE. Parity error generated/received by CS1301/CS1311. PCI_SERR# H2 OD System Error. This signal is asserted when operating as a target and detecting an address parity error. PCI_INTA# C9 I/OD PCI_INTB# A8 I/O/OD PCI Interrupts A, B, C, and D. Can operate as an input (power-up default) or output, as determined by direction control bits in PCI MMIO register INT_CTL. PCI_INTC# B8 I/OD PCI_INTD# A7 I/OD ID Select. Used as chip select during configuration read/write cycles. As an input, PCI_INT# can be used to receive PCI interrupt requests (normal PCI use is active low, level-sensitive mode, but the VIC can be set to treat these as a positive edge triggered mode). As an input, PCI_INT# can also be used as a general interrupt request if not needed for PCI. As an output, the value of a PCI_INT# can be programmed through PCI MMIO registers to generate interrupts for other PCI masters. Note: Revision 2.2 Current buffer design allows drive/receive from either 3.3V or 5.0V PCI bus. 15 www.national.com Geode™ CS1301/CS1311 Signal Definitions (Continued) Geode™ CS1301/CS1311 Signal Definitions (Continued) 2.2.4 Video In Interface Signals Signal Name Ball No Type VI_CLK C20 I/O Description Clock. This signal can be configured as either an input or an output: If configured as an input (power-up default): A positive transition on this incoming video clock pin samples VI_DATA[09:00] if VI_DVALID is high. If VI_DVALID is low, VI_DATA[09:00] is ignored. Clock and data rates of up to 81 MHz are supported. The CS1301/CS1311 supports an additional mode where VI_DATA[09:08] in message passing mode are not affected by the VI_DVALID signal. If configured as an output: VI_CLK performs as a programmable output clock to drive an external video A/D converter. It can be programmed to emit integral dividers of DSPCPU_CLK. If used as an output, a board level 27 to 33Ω series resistor is recommended to reduce ringing. A17 I Data Valid. VI_DVALID indicates that valid data is present on VI_DATA[09:00]. If high, VI_DATA will be accepted on the next VI_CLK positive edge. If low, VI_DATA[09:00] will not be sampled. However, the CS1301/CS1311 supports an additional mode where VI_DATA[9:8] in message passing mode are not affected by the VI_DVALID signal. VI_DATA[07:00] B18, C17, A19, A20, B19, B20, C19, D18 I Data Bus Lines [7:0]. CCIR-656 style YUV 4:2:2 data from a digital camera or general purpose high speed data input pins. Sampled on VI_CLK if VI_DVALID is high. VI_DATA[09:08] B17, A18 VI_DVALID Note: Data Bus Lines [9:8]. Extension high speed data input bits to allow use of 10-bit video A/D converters in raw10 modes. VI_DATA serves as START and VI_DATA as END message input in message passing mode. Sampled on positive transitions of VI_CLK if VI_DVALID is high. The CS1301/CS1311 supports an additional mode where VI_DATA[09:08] in message passing mode are not affected by the VI_DVALID signal. Video In and Audio In are supported by third party software solutions, not by the National solution. www.national.com 16 Revision 2.2 2.2.5 Video Out Interface Signals Signal Name Ball No. Type VO_CLK J19 I/O Description Clock. The VO module emits VO_DATA[07:00] on a positive edge of VO_CLK. VO_CLK can be configured as an input (reset default) or output. If configured as an input: VO_CLK is received from external display clock master circuitry. If configured as an output: The CS1301/CS1311 emits a programmable clock frequency. The emitted frequency can be set between approximately 4 and 81 MHz with a sub-Hertz resolution. The clock generated is frequency accurate and has low jitter properties due to a combination of an on-chip DDS (Direct Digital Synthesizer) and VCO/PLL. If used as an output, a board level 27 to 33Ω series resistor is recommended to reduce ringing. VO_IO1 J18 I/O Input/Output 1. This pin can function as HS (Horizontal Sync) output or as STMSG (Start Message) output. If set as HS output: VO_IO1 outputs the HS output signal. In message passing mode, VO_IO1 acts as the STMSG output signal. VO_IO2 H20 I/O Input/Output 2. This pin can function as FS (Frame Sync) input, FS output or as ENDMSG (End Message) output. If set as FS input, it can be set to respond to positive or negative edge transitions. If the VO module operates in external sync mode and the selected transition occurs, the VO module sends two fields of video data. Note: this works only once after a reset. In message passing mode, this pin acts as ENDMSG output signal. VO_DATA[07:00] Revision 2.2 K20, K12, M20, M19, M18, N20, N19, P20 O Data Bus.

This output can be programmed to emit any frequency up to 40 MHz with a sub-Hertz resolution. It is intended for use as the 256fs or 384fs over-sampling clock by external A/D subsystem. A board level 27 to 33Ω series resistor is recommended to reduce ringing. AI_SCK A16 I/O Serial Clock. When the AI module is programmed as a serial-interface timing slave (power-up default), AI_SCK is an input. AI_SCK receives the serial bit clock from the external A/D subsystem. This clock is treated as fully asynchronous to the CS1301/CS1311 main clock. Description When the AI module is programmed as the serial-interface timing master, AI_SCK is an output. AI_SCK drives the serial clock for the external A/D subsystem. The frequency is a programmable integral divisor of the AI_OSCLK frequency. AI_SCK is limited to 22 MHz. The sample rate of valid samples embedded within the serial stream is variable. If used as an output, a board level 27 to 33Ω series resistor is recommended to reduce ringing. AI_SD C15 I Serial Data. Serial data from external A/D subsystem. Data on this pin is sampled on positive or negative edges of AI_SCK as determined by the CLOCK_EDGE bit in the AI_SERIAL register. AI_WS B16 I/O Word-Select. AI_WS is the word-select or frame-synchronization signal from/to the external A/D subsystem. When the AI module is programmed as the serial-interface timing slave (power-up default), AI_WS acts as an input. AI_WS is sampled on the same edge as selected for AI_SD. When the AI module is programmed as the serial-interface timing master, AI_WS acts as an output. It is asserted on the opposite edge of the AI_SD sampling edge. Note: The AI module always acts as receiver, but can be master or slave for A/D timing. Video In and Audio In are supported by third party software solutions, not by the National solution. www.national.com 18 Revision 2.2 2.2.7 Audio Out Interface Signals Signal Name Ball No. Type AO_OSCLK B14 O Over-Sampling Clock. This output can be programmed to emit any frequency up to 40 MHz, with a sub-Hertz resolution. It is intended for use as the 256 or 384 fs over-sampling clock by the external D/A conversion subsystem. A board-level 27 to 33Ω series resistor is recommended to reduce ringing. AO_SCK A14 I/O Serial Clock. When the Audio Out (AO) module is programmed to act as the serial interface timing slave (power-up default), AO_SCK acts as an input. It receives the Serial Clock from the external audio D/A subsystem. The clock is treated as fully asynchronous to the CS1301/CS1311 main clock. Description When the AO module is programmed to act as the serial interface timing master, AO_SCK acts as an output. It drives the serial clock for the external audio D/A subsystem. The clock frequency is a programmable integral divisor of the AO_OSCLK frequency. AO_SCK is limited to 22 MHz. The sample rate of valid samples embedded within the serial stream is variable. If used as an output, a board-level 27 to 33Ω series resistor is recommended to reduce ringing. AO_SD1 B13 AO_SD2 A13 AO_SD3 C12 AO_SD4 B12 AO_WS A15 O Serial Data Buses. Serial data to external stereo audio D/A subsystem. The timing of transitions on this output is determined by the CLOCK_EDGE bit in the AO_SERIAL register, and can be on positive or negative AO_SCK edges. I/O Word-Select or Frame synchronization. Signal from/to the external D/A subsystem. Each audio channel receives 1 sample for every WS period. When the AO module is programmed as the serial interface timing slave (power-up default), AO_WS acts as an input. AO_WS is sampled on the opposite AO_SCK edge from which AO_SDx are asserted. When the AO module is programmed as serial interface timing master, AO_WS acts as an output. AO_WS is asserted on the same AO_SCK edge as AO_SDx. Note: 2.2.8 The AO module always acts as sender, but can be master or slave for D/A timing. S/PDIF Interface Signals Signal Name Ball No. Type SPDO A12 O Revision 2.2 Description S/PDIF Data Out. Self-clocking serial data stream as per IEC958, with 1937 extensions. Note that the low impedance output buffer requires a 27 to 33Ω series terminator close to CS1301/CS1311 in order to match the board trace impedance. This series terminator must be part of the voltage divider needed to create the coaxial output through the AC isolation transformer. 19 www.national.com Geode™ CS1301/CS1311 Signal Definitions (Continued) Geode™ CS1301/CS1311 Signal Definitions (Continued) 2.2.9 ACCESS.bus Interface Signals Signal Name Ball No. Type Description IIC_SDA R19 I/OD ACCESS.bus Serial Data.
