Abstract:

The simple parallel computing or single heterogeneous platform can no longer meet the requirements of signal processing and task schedulingwith large computation and high complexity, so heterogeneous multi platform system has become the development trend of signal processing and task scheduling. In view of improving the throughput of the platform, utilization rate of the processor and perception of the task,this study investigates the signal processing model of heterogeneous multi-platform, and the scheduling tasks and hardware and software resources are modeled by directed acyclic graph.Based on the proposed scheduling algorithms, the task scheduling is summarized and compared. It is found that the hybrid scheduling algorithm based on task perception can meet the platform scheduling requirements well.It is a trend of future research to use mixed scheduling algorithm based on task perception to solve task scheduling in signal processing.

Key words: heterogeneous platform signal processing, software system, hardware architecture, task scheduling, task perception, algorithm classification, directed acyclic graph, hybrid algorithm
