A processor access module receives a data command from an agent located externally of a computing processor and performs a cache operation on a cache memory in the computing processor based on the data command. Alternatively, the processor access module receives a data command from the agent and performs a cache operation on the cache memory based on the data command to store a computer program into the cache memory. The processor access module then receives a boot command from the agent and boots the computing processor to initiate execution of the computer program.
