VLIW ACCELERATION SYSTEM USING MULTI-STATE LOGIC

摘要

A logic simulation processor uses multi-state logic (e.g., in 4-state, signals may take the values 0, 1, X or Z in the simulation of a semiconductor chip design). Typically a reduced number of basic multi-state logic functions are selected for the instruction set of the processor. Logic functions that are not part of the basic set are simulated by constructing them from combinations of the basic logic functions. In this way, the instruction length remains a manageable size but all logic functions that may occur can be simulated. The basic VLIW architecture can be extended to other applications.
