An Airborne Multi-core Processor Based on AMP Architecture
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.
