Description
technical field [0001] The present invention relates to the technical field of task scheduling, in particular to a task scheduling system and a scheduling method for a heterogeneous multi-core platform. Background technique [0002] Moore's Law states that the number of transistors that can be accommodated on a monolithic integrated circuit will double every 18-24 months, and the performance will double accordingly. With the advancement of chip manufacturing technology, the number of transistors that can be integrated on a single chip has exceeded 100 million. With the increase of chip integration, the clock frequency of the processor continues to increase, but limited by the physical properties of the processor material, processing The clock frequency of the processor has stopped increasing or even decreased, and the performance improvement of the single-core processor has encountered a bottleneck. However, the constant changes in modern application requirements urgently r...
