摘要:
Method and system for loading processor boot code from a serial flash memory device. A code fetch request is received from a processor, the code fetch request requesting a portion of boot code to be executed by the processor. The code fetch request is translated into a memory request providing random access to the serial flash memory device, and the memory request is sent to the serial flash memory. The portion of boot code is read from the serial flash memory device and provided to the processor.
