ABSTRACT:
A system, method, and apparatus for dynamically booting processor code memory with a wait instruction is presented herein. A wait instruction precedes the transfer of a new code portion to the code memory. The wait instruction causes the processor to temporarily cease using the code memory. When the processor ceases using the code memory, the processor signals a direct memory access (DMA) module to transfer a new code portion to the code memory. The DMA module transfers the new code portion to the code memory and transmits a signal to the processor when the transfer is completed. The signal causes the processor to resume. When the processor resumes, the processor begins executing the instructions at the next code address.
