Abstract
A method and apparatus for improving the efficiency of a processor-based emulation engine. The emulation engine is composed of a plurality of processors, each processor capable of emulating a logic gate. Processors are arranged into groups of processors called clusters. Each processor receives inputs, processes the inputs, and stores the outputs in an output array. The output array allows processors within a cluster to fetch an output from a processor that was written to the output array during a previous cycle. The output array can also store and transfer data between clusters of processors. Consequently, the number of cycles that a processor or a cluster has to wait to fetch data is greatly reduced and the efficiency of the emulation engine is increased.
