This paper designs a fast,scalable and accurate architecture simulator(MVSim)for VLIW multi-core vector processors.The scalable VLIW multi-core vector processor model,multi-level storage architecture model and multi-core performance model are designed in MVSim.It implements cycle-accurate simulation of instruction set architectures,efficient functional simulation of Cache,DMA and multi-core synchronization,and uses multi-threading to achieve efficient and scalable simulation of multi-core processors.The experimental results show that MVSim can accurately simulate the program execution of the target multi-core processor,the simulation results are completely correct,and it has good scalability.The average simulation speed of MVSim is 227 times and 5 times faster than RTL simulator and CCS,respectively,and the average performance error is about 2.9%.
