  • Method and apparatus for increasing the data storage rate of a computer system having a predefined data path width
    Patent number: 5019965
    Abstract: In a computer system, the flow of data from the execution unit to the cache 28 is enhanced by pairing individual, sequential longword write operations into a simultaneous quadword write operation. Primary and secondary writebuffers 50, 52 sequentially receive the individual longwords during first and second clock cycles and simultaneously present the individual longwords over a quadword wide bus to the cache 28. During the first clock cycle, when the cache 28 is not performing the quadword write operation, the cache 28 is free to perform the requisite lookup routine on the address of the first longword of data to determine if the quadword of address space is available in the cache. Thus, the flow of data to the cache 28 is maximized.
