【Abstract】 Aiming at the problems of large loss of verification process and low verification accuracy of the currently designed multi-core chip low-power verification system,a new multi-core chip low power verification system is designed based on CNN. The hardware structure is composed of microprocessor,write buffer,program memory and SDRAM interrupt controller.The microprocessor is externally connected with three interfaces to reduce power consumption through static design,and the write buffer replaces the data.The SDRAM interrupt controller is used to control the system circuit when the single chip microcomputer is powered on and reset.CNN technology is introduced to complete the system software operation through concentration verification,low power feature reproduction and verification system establishment.The experimental results show that the multi-core chip low power verification system based on CNN can effectively reduce the loss of verification process by 10% and improve the accuracy by 15%.更多还原
