Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of integrated circuit design and computer system, and particularly relates to a resource allocation isolation system and method of a heterogeneous operating system, and a storage medium. BACKGROUND

[0002] In the field of integrated circuit design and computer system, multi-core homogeneous SoC (System on Chip) is widely used in embedded systems, storage control and other fields due to its integration of multiple same-architecture processor cores, sharing of system resources (such as memory, bus, etc.) and support for parallel processing. Its core features include: architecture consistency and development convenience and scalability.

[0003] All processor cores use the same instruction set and microarchitecture (such as ARM Cortex-A73, RISC-V C910), and data consistency is achieved through shared cache (Cache) or unified memory access (UMA), which simplifies task scheduling and resource allocation. Iron C910MP can be used to achieve multi-core collaboration through superscalar architecture and shared bus. The same architecture reduces software adaptation complexity, and the compilation and debugging tools can be uniformly applied; by increasing the number of cores, the computing power can be linearly improved, and the multi-shot and multi-channel prefetching technology of Iron C910 can be used.

[0004] Multi-core homogeneous SoC often runs multiple operating systems to form an AMP (Asymmetric Multiprocessing) heterogeneous system. For example, in the JFMQL100TAI900 chip, Core0~Core2 run the non-real-time system Linux, and Core3 runs the real-time operating system, forming a typical heterogeneous system architecture.

[0005] The existing resource isolation method of heterogeneous operating systems mainly includes the isolation of CPU cores, memory, interrupts and various peripheral controllers, which is achieved through the following steps:

[0006] (1) Non-real-time system resource configuration: disable and reserve the resources required by the real-time operating system through the Linux device tree, and obtain resource information and initialize the system through the Linux device tree parsing system;

[0007] (2) Real-time system configuration generation: manually enable the control macro of the corresponding resource in the real-time operating system configuration file, and generate the real-time operating system image after compilation.

[0008] The existing technology has the problems that the configuration process relies on manual operation, and resources need to be configured independently in the Linux device tree and the real-time system configuration file, which is tedious and prone to errors due to parameter conflicts or omissions. Moreover, the fault tolerance is poor, and configuration errors may cause the real-time operating system to fail to start or crash during operation, affecting the stability and reliability of the heterogeneous system.

[0009] In view of this, the present application is proposed. SUMMARY
