Abstract
Methods and apparatus for an inter-processor communication (IPC) link between two (or more) independently operable processors. In one aspect, the IPC protocol is based on a 'shared' memory interface for run-time processing (i.e., the independently operable processors each share (either virtually or physically) a common memory interface). In another aspect, the IPC communication link is configured to support a host driven boot protocol used during a boot sequence to establish a basic communication path between the peripheral and the host processors. Various other embodiments described herein include sleep procedures (as defined separately for the host and peripheral processors), and error handling.
