Abstract
Clusters of processors are interconnected as an emulation engine such that processors share input and data stacks, and the setup and storing of results are done in parallel, but the output of one evaluation unit is connected to the input of the next evaluation unit. A set of 'cascade' connections provides access to the intermediate values. By tapping intermediate values from one processor, and feeding them to the next, a significant emulation speedup is achieved.
