Method for processing RISC instruction and custom instruction parallely and configurable processor using thereof

摘要

PURPOSE: A method for processing RISC instruction and custom instruction in parallel and a configurable processor using thereof are provided to reduce the total running time of the calculation including the extended instruction. CONSTITUTION: A list information register(120) stores the list information about the extended instruction which is executed in the customized function unit. A dependency detector(110) decides the dependency of extended instruction executed in the customized function unit and the RISC(Reduced Instruction Set Computer) instruction processed in a decoder(143). The dependency detector stalls pipes(142,145) connected to the decoder.
