ZC.MuNiu OS Product Manual Based on ARM CORTEX R52+

Introduction

ZC.MuNiu Operating System ARM CORTEX R52+ product complies with AUTOSAR and OSEK (ISO17356-3) standards, supporting multi-cluster and multi-core architectures. ZC.MuNiu Operating System ARM CORTEX R52+ product implements task preemptive scheduling, and efficient interrupt processing framework, providing good assurance for system real-time performance. ZC.MuNiu Operating System ARM CORTEX R52+ product includes configuration tool that can achieve flexible configuration and tailoring, can automatically generate configuration source code and application reference frameworks. It can significantly reduce the development costs of automotive electronic control units.

The ARM CORTEX R52+ architecture supports the configuration of multiple clusters, with each cluster containing multiple physical cores. ZC.MuNiu Operating System ARM CORTEX R52+ product supports multi-cluster and multi-core architectures and has excellent hardware adaptability. ZC.MuNiu Operating System ARM CORTEX R52+ product supports the ARM GIC V3.0 interrupt architecture, implementing static configuration of interrupt parameters, interrupt installation, and interrupt routing mechanisms in non-virtual machine modes, effectively ensuring system real-time performance. By the characteristics of the ARM CORTEX R52+ architecture, key algorithms such as task scheduling and inter-core communication are optimized to improve system performance.

ZC.MuNiu Operating System ARM CORTEX R52+ product has an lightweight memory protection and timing protection framework, which can effectively prevent low-safety-level applications from accessing illegal memory areas and prevent unexpected timing behavior in low-safety-level applications. Thereby achieving fault isolation and enabling the coexistence of multiple functional safety level applications in the system. The service protection mechanism determines whether the application's call complies with the rules defined in the standard, preventing unexpected behavior caused by non-standard implementation. The stack protection mechanism provides real-time monitoring of the stack usage of tasks and interrupts, preventing stack overflow in tasks or interrupts, and further improving system safety.

ZC.MuNiu Operating System ARM CORTEX R52+ product can be deeply customized and optimized for microcontrollers (MCU) in the automotive field, as well as for the safety islands integrated in controllers. ZC.MuNiu Operating System (OS) product has characteristics of execution efficiency and flexible code deployment.

ZC actively invests in the adaptation of domestic chips, taking the lead in adapting to the products of domestic chip manufacturers such as Flagchip and AutoChips Inc. ZC will continuously improving the compatibility and support of ZC.MuNiu basic software for domestic chips.

ZC has the core technology of the AUTOSAR basic software. Can provide on-site support with high quality, fast speed, and low cost.
