A.1.2 CPU Module
The CPU module provides control, signaling, and LAN server functions for the switch. A 32-bit RISC processor
(i960CF, 33 MHz) operates all switch software options.
An on-board Segmentation and Reassembly (SAR) ASIC provides rapid packet processing. A common DRAM bank
stores both CPU data structures and SAR processing buffers. Sixteen megabytes of DRAM is standard; 64 MB is
optional.
512 KB SRAM supports up to 4096 VCs routed through the CPU module.
