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, which validates the achievement.
