METHOD AND BUS PREFETCHING MECHANISM FOR IMPLEMENTING ENHANCED BUFFER CONTROL |
摘要 |
A method, and bus prefetching mechanism are provided for implementing enhanced buffer control. A computer system includes a plurality of masters and at least one slave exchanging data over a system bus and the slave prefetches read data under control of a master. The master generates a continue bus signal that indicates a new or a continued request. The master generates a prefetch bus signal that indicates an amount to prefetch including no prefetching. The master includes a mechanism for continuing a sequence of reads allowing prefetching until a request is made indicating a prefetch amount of zero.
