Information processing apparatus and error correction method

An information processing system comprising:

• a processor;
• a memory configured to store instructions and error correction codes corresponding to the instructions;
• a memory interface module configured to read one of the instructions stored in the memory in accordance with a memory address designated by a fetch request from the processor;
• an error detection module configured to detect an error in the read instruction with the error correction code corresponding to the read instruction;
• and
• an instruction transmitter configured to send to the processor a first instruction to store the memory address designated by the fetch request into a stack and a second instruction to jump to an error correction module for correcting an error of the read instruction instead of sending the read instruction upon detection of the error in the read instruction, wherein the memory address stored in the stack is loaded on a program counter of the processor after completion of an error correction by the error correction module.

An error correction method comprising:

• reading an instruction stored in a memory in accordance with a memory address designated by a fetch request from a processor;
• detecting whether an error exists in the read instruction;
• sending to the processor a first instruction to store the memory address designated by the fetch request into a stack and a second instruction to jump to an error correction module for correcting an error of the read instruction upon detection of the error in the read instruction;
• and
• loading the memory address in the stack on a program counter of the processor after completion of an error correction by the error correction module.
