The CS4970x4 DSP family is an enhanced version of the
CS4953x DSP family with higher overall performance. In
addition to all the mainstream audio processing codes in onchip ROM that the CS4953x DSP offers, the CS4970x4 device
family also supports the decoding of major high-definition
audio formats. Additionally, the CS4970x4, a dual-core device,
performs the high-definition audio decoding on the first core,
leaving the second core available for audio post-processing and
audio enhancement. The CS4970x4 device supports the most
demanding audio post processing requirements. It provides an
easy upgrade path to systems currently using the CS495xx or
CS4953x device with minor hardware and software changes.

2.1 Migrating from the CS495xx(2) to the CS4970x4
The CS4970x4 was designed to provide an easy upgrade path from the CS495xx & CS4953x. Although 144-pin
versions of the two devices are virtually identical with respect to external system connection, there are some small
differences the hardware designer should be aware of:
• The PLL supply voltage on the CS4970x4 is 3.3V vs. 1.8V on the CS495xx.
• The PLL filter topology is simpler when using the CS4970x4 rather than the CS495xx.
• The CS4970x4 adds support for 6-channel DSD input.
• The CS4970x4 adds support for TDM mode on both audio input and output ports.
• The CS4970x4 does not support external SRAM operation.
• The CS4970x4 external SDRAM bus speed is fixed at 150 MHz vs. the 120 MHz max bus speed for the
CS495xx. Some firmware modules also support a 75 MHz CS4970x4 SDRAM bus speed. Please refer to
AN304 for details.
• The CS4970x4 CLKOUT pin can output XTALI or XTALI/2. The CS495xx can only output XTALI.
2.2 Licensing
Licenses are required for all of the third party audio decoding/processing algorithms listed below, including the
application notes. Please contact your local Cirrus Sales representative for more information.
3. Code Overlays
The suite of software available for the CS4970x4 family consists of operating systems (OS) and a library of
overlays. The overlays have been divided into three main groups called Decoders, Matrix-processors, and Postprocessors. All software components are defined in the following list:
• OS/Kernel - Encompasses all non-audio processing tasks, including loading data from external memory,
processing host messages, calling audio-processing subroutines, auto-detection, error concealment, etc.
• Decoders - Any Module that initially writes data into the audio I/O buffers, e.g. AC-3™, DTS, PCM, etc. All
the decoding/processing algorithms listed require delivery of PCM or IEC61937-packed, compressed data via
I2S- or LJ-formatted digital audio to the CS4970x4 from A/D converters, SPDIF Rx, HDMI Rx, etc.
• Matrix-processors - Any module that processes audio I/O buffer PCM data in-place before the Postprocessors. Generally speaking, these modules alter the number of valid channels in the audio I/O buffer
through processes like Virtualization (nÖ2 channels) or Matrix Decoding (2Ön channels). Examples are Dolby
ProLogic IIx and DTS Neo:6.
• Virtualizer-processor - Any module that encodes PCM data into fewer output channels than input channels
(nÖ2 channels) with the effect of providing “phantom” speakers to represent the physical audio channels that
were eliminated. Examples are Dolby Headphone® 2 and Dolby Virtual Speaker® 2. Generally speaking, these
modules reduce the number of valid channels in the audio I/O buffer.
• Post-processors - Any module that processes audio I/O buffer PCM data in-place after the Matrix-Processors.
Examples are Bass Management, Audio Manager, Tone Control, EQ, Delay, Customer-specific Effects, Dolby
Headphone/Virtual Speaker, etc.
The overlay structure reduces the time required to reconfigure the DSP when a processing change is requested. Each
overlay can be reloaded independently without disturbing the other overlays. For example, when a new decoder is
selected, the OS, matrix-, and post-processors do not need to be reloaded — only the new decoder (the same is true
for the other overlays).

CS4970x4 Data Sheet
32-bit High Definition Audio Decoder DSP Family
4. Hardware Functional Description
4.1 Coyote DSP Core
The CS4970x4 is a dual-core Coyote DSP with separate X and Y data and P code memory spaces. Each core is a
high-performance, 32-bit, user-programmable, fixed-point DSP that is capable of performing two multiply
accumulate (MAC) operations per clock cycle. Each core has eight 72-bit accumulators, four X- and four Y-data
registers, and 12 index registers.
Both DSP cores are coupled to a flexible DMA engine. The DMA engine can move data between peripherals such
as the digital audio input (DAI) and digital audio output (DAO), external memory, or any DSP core memory, all
without the intervention of the DSP. The DMA engine offloads data move instructions from the DSP core, leaving
more MIPS available for signal processing instructions.
CS4970x4 functionality is controlled by application codes that are stored in on-board ROM or downloaded to the
CS4970x4 from a host MCU or external FLASH/EEPROM. Users can choose to use standard audio decoder and
post-processor modules which are available from Cirrus Logic.
The CS4970x4 is suitable for Audio Decoder, Audio Post-processor, Audio Encoder, DVD Audio/Video Player, and
Digital Broadcast Decoder applications.
4.1.1 DSP Memory
Each DSP core has its own on-chip data and program RAM and ROM and does not require external memory for any
of today’s popular audio algorithms including Dolby Digital Surround EX, AAC Multichannel, DTS-ES 96/24, and
THX Ultra2. However, if the end-system design requires support of the new high-definition audio formats, external
SDRAM will be needed to support Dolby TrueHD and DTS-HD Master Audio.
The memory maps for the DSPs are as follows. All memory sizes are composed of 32-bit words.

4.1.2 DMA Controller
The powerful 12-channel DMA controller can move data between 8 on-chip resources. Each resource has its own
arbiter: X, Y, and P RAM/ROMs on DSP A; X, Y, and P RAM/ROMs on DSP B; external memory; and the
peripheral bus. Modulo and linear addressing modes are supported, with flexible start address and increment
controls. The service interval for each DMA channel as well as up to 6 interrupt events, is programmable.
4.2 On-chip DSP Peripherals
4.2.1 Digital Audio Input Port (DAI)
The 12-channel (6 line) DAI port supports a wide variety of data input formats. The port is capable of accepting
PCM, IEC61937, or DSD. Up to 32-bit word lengths are supported. Up to 6 channels of DSD are supported and
internally converted to PCM before processing. Additionally support is provided for audio data input to the DSP via
the DAI from an HDMI receiver.

CS4970x4 Data Sheet
32-bit High Definition Audio Decoder DSP Family
The port has two independent slave-only clock domains. Each data input can be independently assigned to a clock
domain. The sample rate of the input clock domains can be determined automatically by the DSP, which off-loads
the task of monitoring the SPDIF receiver from the host. A time-stamping feature allows the input data to be
sample-rate converted via software.
4.2.2 Digital Audio Output Port (DAO)
There are two DAO ports. Each port can output 8 channels of up to 32-bit PCM data. The port supports data rates
from 32 kHz to 192 kHz. Each port can be configured as an independent clock domain in slave mode, or the ratio of
the two clocks can be set to even multiples of each other in master mode. The two ports can also be ganged together
into a single clock domain. Each port has one serial audio pin that can be configured as a 192 kHz SPDIF transmitter
(data with embedded clock on a single line).
4.2.3 Serial Control Port 1 & 2 (I2C™ or SPI™)
There are two on-chip serial control ports that are capable of operating as master or slave in either I2C or SPI modes.
SCP1 defaults to slave operation. It is dedicated for external host-control and supports an external clock up to 50
MHz in SPI mode. This high clock speed enables very fast code download, control or data delivery. SCP2 defaults
to master mode and is dedicated for booting from external serial Flash memory or for audio sub-system control.
4.2.4 Parallel Control Port
The CS4970x4 parallel port supports both Motorola® and Intel® interfaces. It can be used for both control and data
delivery. The parallel port pins are multiplexed with serial control port 2 and are available in the 144-pin package.
4.2.5 External Memory Interface
The external memory interface controller supports up to 128 Mbits of SDRAM, using a 16-bit data bus.
4.2.6 GPIO
Many of the CS4970x4 peripheral pins are multiplexed with GPIO. Each GPIO can be configured as an output, an
input, or an input with interrupt. Each input-pin interrupt can be configured as rising edge, falling edge, active-low,
or active-high.
4.2.7 PLL-based Clock Generator
The low-jitter PLL generates integer or fractional multiples of a reference frequency which are used to clock the
DSP core and peripherals. Through a second PLL divider chain, a dependent clock domain can be output on the
DAO port for driving audio converters. The CS4970x4 defaults to running from the external reference frequency
and can be switched to use the PLL output after overlays have been loaded and configured, either through master
boot from an external FLASH or through host control. A built-in crystal oscillator circuit with a buffered output is
provided. The buffered output frequency ratio is selectable between 1:1 (default) or 2:1.
4.3 DSP I/O Description
4.3.1 Multiplexed Pins
Many of the CS4970x4 pins are multi-functional. For details on pin functionality please refer to the CS4970x4
System Designer’s Guide.
4.3.2 Termination Requirements
Open-drain pins on the CS4970x4 must be pulled high for proper operation. Please refer to the CS4970x4 System
Designer’s Guide to identify which pins are open-drain and what value of pull-up resistor is required for proper
operation.

Mode select pins on the CS4970x4 are used to select the boot mode upon the rising edge of reset. A detailed
explanation of termination requirements for each communication mode select pin can be found in the CS4970x4
System Designer’s Guide.
4.3.3 Pads
The CS4970x4 I/O operate from the 3.3 V supply and are 5 V tolerant.
4.4 Application Code Security
The external program code may be encrypted by the programmer to protect any intellectual property it may contain.
A secret, customer-specific key is used to encrypt the program code that is to be stored external to the device.

1. Master mode timing specifications are characterized, not production tested.
2. Master mode is defined as the CS4970x4 driving both DAO_SCLK, DAO_LRCLK. When MCLK is an input, it is
divided to produce DAO_SCLK, DAO_LRCLK.
3. This timing parameter is defined from the non-active edge of DAO_SCLK. The active edge of DAO_SCLK is the
point at which the data is valid.
4. Slave mode is defined as DAO_SCLK, DAO_LRCLK driven by an external source.
