摘要
多核处理以其高性能得到了广泛的关注。从多核体系架构出发,分别分析了处理器架构和软件架构,根据机载应用特点,集中讨论了同构型多核处理及AMP,SMP和BMP等软件架构。结合研究现状,针对机载航电系统继承性和增量认证的需求,选择了商用P5020多核处理器,配置了基于AMP架构的天脉操作系统,移植了性能测试用例。测试结果表明,多核处理系统在一定程度上可以实现倍数性能提升,能够满足航空电子系统计算密集型功能应用的需求。
Multi-core processing is widely used due to its high performance.From the perspective of multi-core system architecture,the processor architecture and the software architecture are analyzed respectively.According to the characteristics of airborne applications,homogeneous multi-core processing and software architectures such as AMP,SMP and BMP are discussed.Based on the status quo of researches and to meet the requirements of inheritance and incremental certification for airborne avionics systems,the commercial P5020 multi-core processor is chosen,which is configured with Tianmai operating system based on AMP architecture,and a performance test case is transplanted.The test results show that the multi-core processing system can achieve double performance improvement to a certain extent,which can meet the requirements of computing-intensive applications of avionics systems.
