摘　　要：针对雷达多目标跟踪应用对于计算平台的浮点算力和实时性要求,设计一种基于主处理器加专用加速器架构的低延迟片上系统。通过对多目标跟踪算法各个步骤的深入分析,分别以通道加速器和自定义扩展指令两种形式实现了面向该算法的专用加速器,在FPGA平台上进行专用片上系统原型验证。采用典型数据集测试的结果表明,两种加速器能够有效提升计算平台的整体算力,提高系统的实时性。To meet the floating-point computing power and real-time requirements of the computing platform for radar multi-target tracking applications,a low-latency system-on-chip based on the main processor and dedicated accelerator architecture was designed.The dedicated accelerators for this application were implemented in the form of channel accelerators and custom extension instructions,and a dedicated system-on-chip prototype was verified on the FPGA platform.Tests using typical data sets show that the two accelerators can effectively improve the overall computing power of the computing platform and improve the real-time performance of the system.
