ABSTRACT
<p>A discussion is presented of the use of dynamic storage schemes to improve parallelmemory performance during three important classes of data accesses: vector accesses inwhich multiple strides are used to access a single vector, block accesses, andconstant-geometry FFT accesses. The schemes investigated are based on linear addresstransformations, also known as XOR schemes. It has been shown that this class ofschemes can be implemented more efficiently in hardware and has more flexibility thanschemes based on row rotations or other techniques. Several analytical results areshown. These include: quantitative analysis of buffering effects in pipelined memorysystems; design rules for storage schemes that provide conflict-free access usingmultiple strides, blocks, and FFT access patterns; and an analysis of the effects ofmemory bank cycle time on storage scheme capabilities.</p>
