The invention discloses a visualization method for the optimal division of software and hardware based on a time automaton, comprising the following steps: a workflow modeling step: creating multiple modules by using a graphic modeling framework, and drawing a workflow according to the partial order relationship of each module Model; time automaton model design steps: design a time automaton for each module, and build a time automaton model of the workflow model; resource management step: execute the time automaton model through simulation, and obtain the execution workflow under a single resource allocation strategy The consumption time of the model; the optimal division implementation and feedback steps: obtain the optimal resource allocation strategy with the optimal software and hardware consumption time according to the consumption time, and at the same time visually display the software and hardware under the optimal resource allocation strategy in the graphical modeling framework distribute. The invention efficiently obtains the optimal solution of software and hardware resource allocation, outputs an intuitive solution, and enables software and hardware collaborative engineering to 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...
