Description

Technical field [0001] The invention relates to the technical field of on-chip multi-processor systems, in particular to a hardware synchronization circuit structure suitable for multi-processor systems and an implementation method thereof. Background technique [0002] With the development of technologies such as multimedia and mobile communications, people have higher and higher demands for processor computing capabilities. However, the traditional single-core performance has been greatly restricted due to the constraints of power consumption, memory bandwidth, and operating frequency. Therefore, increasing the parallelism of the processor has become a new breakthrough in improving its computing power. The multi-processor architecture effectively improves the parallelism of computing and meets the requirements of computationally intensive applications. However, the multi-processor architecture does introduce new difficulties in terms of memory data consistency, software program...
