Abstract

A new approach to resource conflict analysis in microcode compaction has been developed. This paper begins with a description of the resource binding problem in microcode compaction and an analysis of earlier solutions. Then a new specification technique is presented and related to a standard problem in combinatorial theory. This new technique allows microoperations to be specified with resource choices, the actual binding to specific resources being delayed until compaction time. A polynomial-time algorithm for analyzing resource conflicts under this model is explained. Further extensions to the algorithm to support more complex machine models are suggested.
