【摘要】 提出并实现了DSP板间的高速数据通道链路(Link)口。它采用低电压差分信号(LVDS)协议,把DSP的64b*30MHz数据流转换成4b*600MHz数据流进行板间传输。链路口基于Altera公司的APEXII系列FPGA实现,并很好地应用于TI公司C6414DSP的板间高速数据传输。该设计已成功应用在运动目标红外凝视探测识别跟踪处理器上。更多还原

【Abstract】 A high-speed data-channel link-port between DSP’s is proposed and implemented. Using LVDS(low voltage differential signaling)protocol, the link-port transforms the 64 b*30 MHz data stream from DSP into (4 (b*)) 600 MHz data stream, which is connected to other link-ports on different boards. Implemented on Altera’s APEXII series FPGA, the link-port performs well on TI C6414 DSP. The design has been applied to a moving target infrared image processor.更多还原
