A method is provided in one example embodiment and includes generating a request for header data, the request is sent to a first processor. The method also includes receiving a response from the first processor that is indicative of video data for a virtual frame to be communicated. A multiplex table is generated based on the response. The method also includes evaluating a multiplex entry in the multiplex table for synchronization with a line number, and requesting the first processor to send at least a portion of the virtual frame after the synchronization. The method further includes communicating a packet, which includes a payload associated with the virtual frame and a packet header that includes multiplex data associated with the multiplex entry.

System and method for data exchange in a heterogeneous multiprocessor system

Systems and methods for real time data processing using a switching network and multiple digital signal processors (DSPs). In an embodiment, the system includes a first digital signal processor having a video port interface, a first interface disposed between the video port interface of the first digital signal processor and a switching network, a second digital signal processor having a video port interface, and a second interface disposed between the video port interface of the second digital processor and the switching network. The first interface is configured to parse a VSYNC line of a video frame that is output from the first digital signal processor via its video port interface to generate a multiplexing table based upon which scan lines of the video frame are broken up into packets compatible with the switching network such that the packets can be transmitted over the switching network and be received by the second interface and the second digital signal processor via its video port interface.
