There are two types of task allocation in multi-core, one is static, that is, when the architecture is designed, which core each task runs on has been determined, and the other is dynamic allocation, according to the current load, operating scenarios, etc. . Whether it is static or dynamic task mapping, how to design a suitable mapping scheme? The first premise is the existing hardware and performance parameter requirements, including load rate, temperature, reliability, etc. For static design, graph theory algorithms, mathematical programming algorithms, or heuristic-based algorithms, such as mathematical programming algorithms, can be used. Convert requirements into mathematical inequalities.
