Using Lookahead to reduce memory bank contention for decoupled operand references
Peter L. Bird, Richard Uhlig · 1991
We introduce a storage system control structure which employs lookahead to minimize the incidence of bank collisions for operand references in memory systems with interleaved banks.We show that by employing lookahead a memory system achieves high data throughput with only a small interleave factor.5'imulation results show that an 8 bank system with lookahead performs as well, or better, than a 32 bank system without Iookahead.A Iookahead controller simplifies the design of bank management hardware, thus reducing the complexity of high throughput memory designs.
