摘要

A discussion is presented of the use of dynamic storage schemes to improve parallel memory performance during three important classes of data accesses: vector accesses in which multiple strides are used to access a single vector, block accesses, and constant-geometry FFT accesses. The schemes investigated are based on linear address transformations, also known as XOR schemes. It has been shown that this class of schemes can be implemented more efficiently in hardware and has more flexibility than schemes based on row rotations or other techniques. Several analytical results are shown. These include: quantitative analysis of buffering effects in pipelined memory systems; design rules for storage schemes that provide conflict-free access using multiple strides, blocks, and FFT access patterns; and an analysis of the effects of memory bank cycle time on storage scheme capabilities.
