HANDLING OF COPROCESSOR INSTRUCTION IN DATA PROCESSOR

摘要

PROBLEM TO BE SOLVED: To multiple coprocessors by a small number of coprocessor numbers. SOLUTION: This data processor in which multiple coprocessors are provided in a plurality of coprocessor instructions capable of executing coprocessor instructions to the respective coprocessor instructions having related virtual coprocessor numbers allocates the virtual coprocessor numbers and determines which coprocessor executes instructions related to the virtual coprocessor numbers by every virtual coprocessor number based on mapping.
