The invention discloses a timed automata based software and hardware optimal-partition visualizing method. The timed automata based software and hardware optimal-partition visualizing method includes a workflow modeling step, a timed automata model design step, a resource management step and an optimal-partition implementing and feedback step, wherein the workflow modeling step includes creating a plurality of models by a graphic modeling framework and drawing a workflow model according to partial ordering relation of the modules; the timed automata model design step includes designing timed automatas for every module and setting up timed automata models of the workflow model; the resource management step includes acquiring consumed time for implementing the workflow model under one-time resource allocation strategy by simulatively implementing the timed automata models; the optimal-partition implementing and feedback step includes acquiring an optimal resource allocation strategy for optimal software and hardware consumption time according to the consumed time and visually displaying software and hardware allocation in the graphic modeling framework under the optimal resource allocation strategy. By the timed automata based software and hardware optimal-partition visualizing method, the optimal solution to the software and hardware resource allocation is effectively obtained, a visual solution is outputted and software and hardware collaborative engineering can be deployed and implemented as soon as possible.
Description
technical field [0001] The invention relates to an embedded system, in particular to a visualization method for optimal division of software and hardware based on time automata. Background technique [0002] An embedded system is a system that integrates software and hardware. The functional modules in the system can be completed by hardware or software. The hardware and software allocation strategy needs to weigh factors such as time, performance, and inter-module constraints. By analyzing the software / hardware combination, it is determined that a single module is implemented by hardware or software. This process is called software / hardware cooperative partitioning of embedded systems. At present, the software / hardware cooperative partition technology of embedded system is still immature, and the structure of embedded system is becoming more and more complex, and the development time requirement is becoming more and more urgent, which makes the software / hardware cooperati...
