A METHOD AND APPARATUS FOR IMPLEMENTING CHECK INSTRUCTIONS THAT ALLOW FOR THE REUSE OF MEMORY CONFLICT INFORMATION IF NO MEMORY CONFLICT OCCURS

摘要

A method and apparatus for implementing check instructions that allow for the reuse of memory conflict information if no memory conflict occurs. According to one aspect of the invention, a machine-readable medium having stored thereon data representing sequences of instructions (380) is described. When executed by a computer system the sequences of instructions (380) cause the computer system to perform a series of steps comprising preloading (384) one of a set of registers data retrieved from a memory starting at a first address, and storing memory conflict information (390) representing the first address. If a memory conflict has occurred between said first and second addresses, then one of the registers (350) is reloaded with the data located at the first address.
