      Research of SAR Signal Processor Based on Multicore DSP 6678

      摘要:
      为了满足雷达成像信号处理系统大数据处理、快速实时性和高集成度的需求,设计和实现了基于TMS320C6678芯片的雷达信号处理机;TMS320C6678内部集成了8个C66x内核,主频最高为1.25 GHz,能提供高达160GFLOPS的浮点运算性能;本系统采用了FPGA搭配DSP的实施方案,实现了基于一片Kintex7 FPGA和一片TMS320C6678高性能实时信号处理平台,可满足雷达成像系统的算法需求,具有较强的实用价值.
      Abstract:
      To meet the needs of radar signal processor for real-time big data processing and high integration, this paper designed and realized the processor based on TMS320C6678.TMS320C6678 has integrated eight C66x kernels with the highest processor speed of 1.25 GHz and can perform 160 G floating-point operations per second.The high performance real-time signal processor has been realized based on the architect of one Kintex7 FPGA plus one TMS320C6678 DSP chip.In conclusion, the signal processor can perfectly satisfy the demands of algorithm for SAR system and has comparatively higher practical value.
