为满足Camera Link相机图像存储系统小型化,可移动,易携带的要求,采用 Xilinx公司V4系列现场可编程门阵列(FPGA)和TI公司6000系列数字信号处理器(DSP)相结合的硬件电路设计方案。首先,在FPGA的控制下,图像数据缓存到一片SDRAM中,同时读出另外一片SDRAM中缓存的图像,经乒乓操作存储到两块固态硬盘中。然后,DSP与上位机用百兆网连接,在上位机的控制下,DSP从外部存储器接口(EMIF)中获取图像数据后,发送给上位机完成实时显示或者存储图像回放的功能。实验表明,在相机分辨率为640×480,帧频为100f/s,像素为10位时,该系统可以不丢帧的完成图像存储任务。在不需要实时显示的应用场合,系统可以单独完成脱机存储任务,基本满足Base型Camera Link相机的便携存储要求。
In order to meet the requirement of miniaturization and portability of the image storage system for camera based on Camera Link interface
the hardware circuit was designed with a Virtex4 family Field Programming Gate Array(FPGA) from Xilinx company and a 6000 series Digital Signal Processor(DSP) from TI company. First
under the control of FPGA
Image data from Camera Link were cached in a SDRAM; at the same time
the image data which read from the other SDRAM were stored in double solid-state hard disks by ping-pang operation. Then the host computer connected with DSP through Fast Ethernet
under the control of the host computer
DSP acquired image data through External Memory Interface (EMIF) and sent it to host computer to realize real-time display or image playback function. The system that based on the scheme stored image successfully
past by the experiment in 640×480
100f/s
10bit monochrome. When the real-time display function is not needed
the designed system could accomplish image storage independently to complete the storage task to meet the Base Camera Link type Camera portable storage requirements.
