ABSTRACT:
A CPU life-extension apparatus and method makes a processor appear to be an upgraded CPU to substantially all software applications accessed thereby, thereby reducing the need and expense of upgrading a selected processor. A CPU life-extension module translates new instructions, intended for a CPU upgrade, into instructions recognized by the processor. In addition, the CPU life-extension module is programmed to monitor reads from and writes to a processor's flags register to modify the flags to emulate those of an upgraded CPU. The CPU life-extension module is configured to respond to interrupts generated by the processor in order to perform its various tasks.
