PCI) that are synchronous / pseudo-synchronous to the CPU bus. The chip

also contains a built-in bus-to-bus bridge to allow simultaneous concurrent

operations on each bus. Five levels (doublewords) of post write buffers are

included to allow for concurrent CPU and PCI operation. For PCI master

operation, forty-eight levels (doublewords) of post write buffers and

sixteen levels (doublewords) of prefetch buffers are included for

concurrent PCI bus and DRAM/cache accesses. The chip also supports

enhanced PCI bus commands such as Memory-Read-Line, Memory-Read-

Multiple and Memory-Write-Invalid commands to minimize snoop

overhead. In addition, advanced features are supported such as snoop

ahead, snoop filtering, L1 write-back forward to PCI master, and L1 write-

back merged with PCI post write buffers to minimize PCI master read

latency and DRAM utilization. Delay transaction and read caching

mechanisms are also implemented for further improvement of overall
