PROCESSOR CORE, PROCESSOR, AND METHOD OF CONTROLLING PROCESSOR

摘要

PROBLEM TO BE SOLVED: To provide a processor core which can execute an arbitrary program different in the multiplicity of branch processing. SOLUTION: The processor core 101 is equipped with a means which identifies an instruction outputted from a program memory 100 stored with a program including instructions, a means which stores the return address of a branch instruction of a 1st type in a 1st memory 125 when the instruction is the branch instruction of the 1st type, and a means which stores the return address of a branch instruction of a 2nd type in a 2nd memory 135 when the instruction is the branch instruction of the 2nd type.
