PROGRAMMABLE PROCESSOR,METHOD FOR EXECUTION OF DIGITAL SIGNAL PROCESSING BY USING SAID PROGRAMMABLE PROCESSOR AND ITS IMPROVEMENT

摘要

PURPOSE: To provide a space vector data path which integrates SIMD schemes to a general purpose programmable processor. CONSTITUTION: A programmable processor includes a mode means which is connected to an instruction means and specifies whether or not an operand is processed for each instruction in one of vector and scalar modes and a processing unit 110 which is connected to the mode means, receives the operand and processes the operand in one of the vector and scalar modes in response to an instruction such that is specified by the mode means. The vector mode shows the processing unit 110 that plural elements exist in the operand and the scalar mode shows the processing unit 110 that a single element exists in the operand.
