Abstract
Methods and apparatus for enabling a peripheral processor to retrieve and load firmware for execution within the constraints of its memory. The peripheral processor is allocated a portion of the host processor's memory, to function as a logical secondary and tertiary memory for memory cache operation. The described embodiments enable the peripheral processor to support much larger and more complex firmware. Additionally, a multi-facetted locking mechanism is described which enables the peripheral processor and the host processor to access the secondary memory, while minimally impacting the other processor.
