Abstract
In a computing system, an in-system programmer includes control logic embedded into the target microprocessor bus address decoder logic, and a memory module in the form of an external device that consists of one or more non-volatile memory chips. With the memory module attached, the microprocessor is led to believe that the in-system programmer is its main memory and the microprocessor turns over control of the computer system to the in-system programmer in an orderly fashion. Program execution comes directly from the in-system memory module. In a stand alone mode the in-system programmer does not require firmware to function. The stand mode is useful in executing temporary firmware without having to alter the target system memory. With embedded programming firmware the in-system programmer is capable of cloning itself in targets that use reprogrammable memory.
