Abstract:
Embodiments of the present invention provide a method for initializing a plurality of processors of a multi-processor system by executing, at each respective processor of the plurality of processors, at least a portion of local initialization code stored on the respective processor. Receiving, at a designated processor of the plurality of processors, external initialization code stored in external memory, wherein the remainder of the plurality of processors do not have access to the external initialization code stored in external memory. Determining, the designated processor, send at least a portion of the external initialization code to a processor of the remainder of the plurality of processors.
