摘要
干涉仪测向分选一般是在DSP中完成,本文介绍了基于DSP的三种不同处理机制.基于多核的分发机制和并发机制都可提高处理的并行性,但并发机制存在多核同步,任务分配等问题,处理效率没有分发机制更高效.分发机制有效利用了干涉仪的本振频点遍历处理特点,流水并行提高了整体处理速度.
Abstract
Interferometer direction finding and sorting are generally completed in DSP.In this paper,three differ-ent processing mechanisms based on DSP are described.Both multi-core distribution and concurrency mechanisms can improve processing parallelism.However,the concurrency mechanism suffers from issues such as multi-core synchronization and task allocation,making it less efficient than the distribution mechanism in processing.The dis-tribution mechanism effectively utilizes the local oscillator frequency point traversal processing characteristics of the interferometer,and pipeline parallel processing improves the overall processing speed.
