摘要：
Buffers are provided in a computer system to allow posting data to the buffers, followed by concurrent operation by different portions of the computer system. A CPU buffer is provided to buffer CPU accesses, a CPU-to-PCI buffer is provided to buffer CPU accesses to the PCI local bus, and a memory buffer is provided to buffer CPU accesses to main memory. This configuration allows the CPU-to-PCI buffer to write data concurrently with the memory buffer accessing data from main memory.
