摘要:
针对新一代机载通信平台减重量、降功耗的需求,指出了当前数据处理平台采用单核或同构多核(Symmetrical Multi-processing,SMP)模式存在重量重、功耗大的问题,提出了数据处理平台采用异构多核(Asymmetrical Multi-processing,AMP)工作模式,从SMP和AMP两种模式的实现架构、工作原理以及实物上展开对比分析并将AMP成果应用到当前的新型机载平台。实物验证对比表明,相较于SMP模式平台,AMP模式平台带来重量减轻近50%、功耗降低近50%的效益。

Abstract:
In view of the requirement of weight reduction and power reduction for the new generation airborne communication platform,the problems of weight and power consumption in the single-core and symmetrical multi-processing(SMP) mode used in existing data processing platform are pointed out.Meanwhile,a data processing platform using asymmetrical multi-processing(AMP) mode is proposed.Then,the implementation mechanism,the realization principle and the physical comparison between SMP and AMP mode are discussed.The AMP mode can be applied in the current new airborne platform.Physical comparison shows the AMP mode can reduce the weight and power consumption by nearly 50% to the SMP model.
