Computer Program Instruction Analysis

摘要

Disclosed is a method of analysis of a computer program instruction for use in a central processing unit having a decoding unit. The method includes receiving an address of an instruction to be analyzed, fetching said instruction stored at said address, decoding by a decoding unit associated with the central processing unit, the fetched instruction, and returning the results of said decoding of said fetched instruction. The decoded results may be returned as a data block stored in memory associated with the central processing unit or in one or more registers of the central processing unit. The decoded results may include the type of the instruction and/or the instruction length. The method may further include analyzing the decoded results to determine whether the instruction may be replaced with one of a trap or a break point.
