snoop operation of 60x bus

hikerwang

anyone can tell the details of this operation, what's the purpose of this operation.
thanks a lot.

The 60x bus can transfer 8 bytes of data in 1 clock cycle. However, with the dead cycle between data tenures,
each transaction, a 32-byte burst, takes 5 clock cycles. Therefore, the theoretical maximum throughput of
the 60x bus with a 100-MHz memory bus speed is 640 MBytes/sec.
Transfer rate = (32 bytes/5 clock cycles) x 100 MHz = 640 MBytes/sec
