Receiving a write request that allows less than one cache line of data to be written and issuing a subsequent write request that requires at least one cache line of data to be written

摘要

A computer system includes a memory device on the first data bus, a device that initiates on a second data bus a write transaction that can involve less than an entire cache line of data, and a bridge device that automatically converts the write transaction into one that requires an entire cache line of data and delivers the converted transaction to the first data bus.
