SUPERSCALAR PROCESSOR AND DATA PROCESSOR

摘要

PROBLEM TO BE SOLVED: To provide a RISC-based high-performance superscalar type processor architecture allowing easy enhancement of an architecture function. SOLUTION: An execution result of an instruction capable of being evacuated in time of completion is stored in a register file, and an execution result of an instruction not capable of being evacuated in time of the completion is stored in a temporary buffer so as to execute the instruction independently of program order and to store the execution results from a plurality of functional units.
