Safety management and control device and method for multi-core processor

Abstract

The invention relates to a safety management and control device and method for a multi-core processor. The device comprises a bus, a plurality of processor cores, a plurality of starting registers anda bus monitor, the plurality of starting registers is arranged corresponding to the plurality of processor cores and used for controlling the safe operation of the corresponding processor cores; andthe bus monitor is used for monitoring the access of each processor to the bus in real time. The bus monitor and the starting registers are arranged, at the beginning of starting, the safety monitoring core performs safety verification on the running environment of each processor core, safe running of the processor cores is controlled through the starting registers, and then the access situation of the processor cores is continuously monitored through the bus monitor in the running process of the processor cores; the safety of the system is comprehensively detected, verified and monitored fromthe starting moment of the system, so that dynamic safety monitoring is realized, and the safety of the system is improved.

Description

technical field [0001] The present disclosure relates to the technical field of multi-core processors, and in particular, to a security management and control device and method for multi-core processors. Background technique [0002] Using a multi-core processor to improve the performance of the processor is a commonly used technology at present. The overall computing power of the processor chip can be improved by integrating multiple identical processor cores in one chip; Heterogeneous processor cores are integrated to form a high-performance processor; multiple general-purpose processor cores, graphics processor cores, and dedicated accelerators can also be integrated to form a high-performance computing core for domain applications. [0003] figure 1 It is an architecture diagram of the processor as the core computing unit of the embedded system in the prior art, such as figure 1 As shown, the processor core is mainly composed of computing components and control compone...

Problems solved by technology

[0004] but, figure 1 In the actual application of the embedded processor shown in the strong real-time embedded system, it is difficult to verify the system security

In a multi-core processor, each processor core executes different programs and performs different functions. Any processor core may be attacked and hijacked. Security issues caused by attacks
