Abstract
Updating code of a single processor in a multi-processor system includes halting transactions processed by a first processor in the system and processing of transactions by a second processor in the system are maintained. The first processor then receives new code and an operating system running on the first processor is terminated whereby all processes and threads being executed by the first processor are terminated. Execution of a self-reset of the first processor is commenced and interrupts associated with the first processor are disabled. Only those system resources exclusively associated with the first processor are reset, and memory transactions associated with the first processor are disabled. An image of the new code is copied into memory associated with the first processor, registers associated with the first processor are reset and the new code is booted by the first processor.
