communication between two dsp on the tmx320C6474

Hi Majid,

The MSGQ module was specifically designed to be used for homogeneous or heterogeneous
multi-processor messaging. It allows for the structured sending/receiving of variable length messages and enables them to be passed transparently between DSP/BIOS executions threads, such as tasks and software interrupts. The MSGQ module internally handles message passing between threads on the same processor.

To pass messages between discrete processors, a message queue transport (MQT) is required for the specific physical inter-processor communication mechanism used, such as peripheral component interconnect (PCI), MCBSP or SRIO.

You can find the IPC examples in BIOS MCSDK released for C6474. The links are below.
