Abstract

A parallel simulation system for a multi-core system comprises a port analog module, a data scrambling scheduling module, a data transfer module and a timing module. The port analog module records and updates idle conditions of output ports and input ports of members in the multi-core system. The data scrambling scheduling module schedules scrambling for communication data to increase utilization rate of ports. The data transfer module transfers the communication data and decreases task awaiting time by means of a local storage. The timing module records time schedule of each member and provides time reference for the data transfer module and the data scrambling scheduling module. The parallel simulation system for the multi-core system can be used to quickly establish a simulation model for hardware environment, so that verification on the static scheduling algorithm of the multi-core system is quickened.

Description

technical field [0001] The invention relates to a parallel simulation system of a multi-core system, which is suitable for quickly verifying static scheduling algorithms of multi-core processors or computer clusters. Background technique [0002] Parallel processing and multi-core technology have become the main trend of current computer development. To give full play to the computing power of the multi-core system, it is necessary to cooperate with an efficient task scheduling algorithm. The task scheduling technology of the current homogeneous multi-core system is relatively mature, and dynamic scheduling can be used to manage and control the execution of tasks. In heterogeneous multi-core processors and computer clusters, dynamic scheduling technology is not yet mature, and static scheduling is still the main choice. Verifying the efficiency of static scheduling algorithms is an indispensable step in task scheduling. Usually, the verification of the static scheduling a...
