Chip resource management method, device, storage medium and system chip

Abstract

The embodiment of the invention discloses a chip resource management method and device, a storage medium and a system chip, and belongs to the technical field of chip security. The method is applied to a system chip. The system chip comprises a security kernel and a common kernel, and the method comprises the following steps: loading first system software through the security kernel, loading a mandatory access control module according to the first system software, controlling a resource management module to allocate a first resource to the security kernel according to the mandatory access control module, and allocating a second resource to the common kernel; loading the second system software through the common kernel, loading the autonomous access control module according to the second system software, and managing the second resource according to the autonomous access control module. According to the embodiment of the invention, the mandatory access control module is deployed in thefirst system software at the bottom layer, so that mandatory isolation of resources of each kernel is realized; an autonomous access control module is deployed in second system software on the upper layer, so that sharing of resources of all kernels is achieved.

Description

Technical field [0001] The embodiments of this application relate to the field of chip security, and in particular to a method, device, storage medium, and system chip for resource management of a chip. Background technique [0002] With the increase in industry demand, semiconductor technology has produced more and more complex system chips (System on Chip, SOC) driven by industry needs. System chips integrate different processor cores and various resources. How to It becomes more and more difficult to effectively manage resources and ensure system security. [0003] In related technologies, the system chip can also be called a multi-core heterogeneous system. The multi-core heterogeneous system includes a secure kernel and multiple ordinary kernels, and the multi-core heterogeneous system manages resources on the secure kernel, which requires more security. The high security kernel is fixed by the hardware and requires private access to resources, and the security kernel schedul...
