摘　　要：针对通用处理器在实现ART算法时的各种限制,提出了基于高性能DSP-TMS320C6678的算法计算方案。该方案结合ART算法的原理,利用TL-XDS560V2硬件仿真器通过USB接口和标准的JTAG接口实现PC端和DSP的连接并使用SDRAM作为数据缓存,从而实现大量数据在两者之间精准快速的传输并在PC端显示验证结果。通过C语言编写DSP片内算法计算程序并对其进行优化以降低图像重建时间,最终实验以某发动机模拟件为实验对象,实验结果证实了方案的可行性。In view of the limitations of common processors in the implementation of ART algorithm,this paper proposes a high-performance DSP-TMS320 C6678 algorithm calculation scheme.Combined with the principle of ART algorithm,this scheme utilizes TL-XDS560 V2 hardware emulator to realize the connection between PC and DSP through USB interface and standard JTAG interface,and uses SDRAM as data cache,so as to realize the accurate and fast transmission of a large amount of data between the two and display the verification results on the PC.DSP in-chip algorithm is programmed by C language and optimized to reduce image reconstruction time.In the final experiment,a simulated engine is used as the experimental object.The experimental results confirm the feasibility of the scheme.
