面向IMA应用的多核处理系统研究与实现
摘要
与单核处理器相比较
多核处理器在性能、功耗、体积、重量以及成本各方面都有绝对的优势
这使得多核处理器在机载嵌入式系统中的应用成为必然趋势.本文在简单分析了IMA实时信息处理需求之后
介绍了系统体系架构设计
重点论述了多核处理节点体系架构、多核应用模式以及单核等价虚拟机模型的设计与实现
最后简单介绍了多核处理系统的测试与验证工作
验证工作表明了研究工作的正确性.
Abstract
Multi-core processors have absolutely advantages over single-core processors in following aspects:performance
power
space、weight and cost
and these advantages lead the application of multi-core processors in airborne embedded system to be inevitable.After analyzing the requirement of information processing in IMA systems
this paper reviews the system architecture
then in detail describes the design and implement of the architecture of processing nodes
multi-processing usage modules and single core equivalence virtual machine module. At end
it simply introduces the test and validation on the multi-core processing system
