RXCRC Block Diagram
RXCRC Functional Description
RXCRC is the second stage in the cell processing pipeline. It performs the ATM CRC-32 (Ethernet FCS) and
ATM CRC-10 functions if necessary. RXCRC gets LCD type, state, and seed information from the LCD
cache, and updates the cache on completion. The results are passed to RXAAL upon completion, along with
the LCD address.
12.19: RXCRC Instruction Array Address Port
This register provides the read/write address for accessing the instruction array. When RXCRC Instruction
Array Read/Write Port is read/written, this register is auto-incremented. When the last address is read/written,
the address rolls over to zero.
