| Abstract: | The structure of high speed infrared image acquired and pre-process system based on FPGA is presented.The circuit adopts many technologies such as module structure design,pipeline style,ping-pang store etc.The real-time performance of data transfer is ensured because the circuit communicates with TMS320C6414 by HPI.The implement technology of image-acquired module,HPI interface module etc.has been given.The experiment results show that the circuit realized 16 bits digital PAL mode image acquire and pre-process and it assumes a lot of computation burden and the real-time performance of whole system is improved greatly. |
