MEMORY RESOURCE DYNAMIC REGULATION AND CONTROL METHOD AND SYSTEM BASED ON MEMORY ACCESS AND PERFORMANCE MODELING

Provided in the present invention are a memory resource dynamic regulation and control method and system based on memory access and performance modeling. By means of technology of guaranteeing quality of service of key applications on real-time multi-core hardware by means of dynamic memory bandwidth resource partitioning, a non-invasive solution with fine granularity, high precision and quick response is provided. In the present invention, an overall architecture of an automatic process performance regulation and control mechanism is designed; by means of a label mechanism, hardware directly acquires the priority of an upper-layer application, so as to provide differentiated hardware resource allocation for processes with different priorities. On the basis of a machine learning method, latency modeling is performed on a bank structure of a dynamic random access memory. For the problem of guaranteeing quality of service of key applications, in a real-time multi-core environment, memory access interference of
