Memory Offset Assignment for DSPs

Compact code generation is very important for an embedded system that has to be implemented on a chip with a severely limited amount of size. Even though on-chip data memory optimization technique has been given more attention, on-chip instruction memory optimization should not be neglected. We propose in this paper some algorithms for a memory offset assignment for embedded DSP processors in order to minimize the number of instructions for address register operations. Extensive experimental results demonstrate the efficacy of our solution.
