摘要：

Software-based ultrasound imaging using commercial DSPs can offer various advantages compared to the conventional FPGA or ASIC based approach. However, it requires multiple DSPs to achieve the real time requirement of medical ultrasound imaging. In this paper, we present a multi-DSP system composed of six ADSP-TS201 DSPs connected with a crossbar switch network. Through efficient task grouping, scheduling, and data flow control, the echo processing function was implemented to support high PRF up to 2.5kHz without code optimization.
