Key modules integrated in the BCM1100 include: • MIPS32 100 MHz processor with 4K 2-way set associative I-cache and a 4K 2-way associative D-cache. This MCU supports the VoIP protocol stacks, jitter buffer management, and application program. Programming is done in C, on top of Broadcom’s objectoriented signal processing API. • ZSP 140 MHz DSP with 48K instruction and 32K data RAM. The DSP supports a wide range of vocoders, acoustic echo cancellation for full-duplex speakerphone, fax modems, and a variety of telephony algorithms (e.g., DTMF and Call Progress Tones). • Analog Codecs. Three ADCs and DACs are integrated, eliminating the need for an analog switch to allow the sharing of a codec between multiple interfaces. • 10/100BASE-T Ethernet Switch, Media Access Controllers, and Transceivers. The three-port Ethernet switch integrates three full-duplex capable Media Access Controllers (MACs), a Serial Management Port, an address resolution engine, a non-blocking switch controller, 64K of internal switch memory, 802.1p prioritization for voice packets, and a set of Management Information Base (MIB) statistics registers. The two transceivers perform all of the functions for 100Base-T Ethernet in full- or half-duplex mode over Category (CAT) 5 twisted pair cable and 10BASE-T Ethernet in full- or half-duplex mode over CAT 3, 4, or 5 twisted pair cable. They support Auto MDI/MDIX detection to allow the use of any cable type in either port. The BCM1100 represents the first silicon solution that integrates all the key silicon components of an Ethernet IP Phone into a single device, thereby reducing the overall system cost and complexity of Enterprise IP Phone products, while at the same time increasing their voice quality and the reliability of the network to which they are attached.
