Application controlled data flow between processing tasks

摘要

In accordance with a preferred embodiment of the present invention, there is provided a way to reduce these memory copy operations by a Java application via API creating task input and output channels which are used to direct communication between Java applications (40), host tasks (48), DSP tasks (60) and device drivers (54). Tasks and devices read input data through task input channels and write output data through task output channels. The channels are connected using a system I/O manager (29) that controls passing data in frame buffers between channels and the tasks or devices to which they are connected. <IMAGE>
