System and method for detecting and recovering from errors in an instruction stream of an electronic data processing system

摘要

A system and method are provided for detecting and recovering from errors in an Instruction Cache RAM and/or Operand Cache RAM of an electronic data processing system. In some cases, errors in the Instruction Cache RAM and/or Operand Cache RAM are detected and recovered from without any required interaction of an operating system of the data processing system. Thus, and in many cases, errors in the Instruction Cache RAM and/or Operand Cache RAM can be handled seamlessly and efficiently, without requiring a specialized operating system routine, or in some cases, a maintenance technician, to help diagnose and/or fix the error.
