The third IPC hardware mechanism is to use SEC_PROXY, which provides an IPC mechanism which carries a large message for complex communications among processors. It allows processors to read and write a message in small chunks.
There are two sets of SEC_PROXY in the device, one SEC_PROXY is dedicated for IPC for HSM M4F, and the second SEC_PROXY is for the rest. When the SEC_PROXY generates events, an IPC message is received or sent, and events are sent to interrupt aggregators before those events are converted into interrupts to the processors. The utilization of SEC_PROXY is user defined through memory map allocation. Each processor can be allocated with its own SEC_PROXY region to receive and send IPC messages.
