Abstract

In a prefetch buffering system and method, a pool of prefetch buffers are organized in such a manner that there is a tight connection between the buffer pool and the data streams of interest. In this manner, efficient prefetching of data from memory is achieved and the amount of required buffer space is reduced. A memory control system controls the reading of data from a memory. A plurality of buffers buffer data read from the memory. A buffer assignment unit assigns a plurality of data streams to the plurality of buffers. The buffer assignment unit assigns to each data stream a primary buffer and a secondary buffer of the plurality of buffers, such that upon receiving a data request from a first data stream, the primary buffer assigned to the first data stream contains fetch data of the data request and the secondary buffer assigned to the first data stream contains prefetch data of the data request.
