本研究评估基于FPGA的嵌入式ARM处理器系统的性能，以实现超声成像和无损检测应用的信号处理。基于FPGA的嵌入式处理器具有许多优点，包括减少总体开发时间，提高性能，以及执行硬件/软件（HW/SW）协同设计的能力。本研究探讨了执行性能的分裂频谱处理，线调频信号分解，Wigner-Ville分布和短时傅立叶变换的实现，在两个嵌入式处理平台：一个Xilinx Virtex-5 FPGA与嵌入式MicroBlaze处理器和一个Xilinx Zynq FPGA与嵌入式ARM处理器。总体而言，Xilinx Zynq FPGA在软件应用方面的性能明显优于基于Virtex-5的系统。
This study evaluates the performance of an FPGA based embedded ARM processor system to implement signal processing for ultrasonic imaging and nondestructive testing applications. FPGA based embedded processors possess many advantages including a reduced overall development time, increased performance, and the ability to perform hardware-software (HW/SW) co-design. This study examines the execution performance of split spectrum processing, chirplet signal decomposition, Wigner-Ville distributions and short time Fourier transform implementations, on two embedded processing platforms: a Xilinx Virtex-5 FPGA with embedded MicroBlaze processor and a Xilinx Zynq FPGA with embedded ARM processor. Overall, the Xilinx Zynq FPGA significantly outperforms the Virtex-5 based system in software applications.
