A networking scheme based on a System-on-a-Programmable-Chip (SOPC) is proposed for a TAU320 infrared camera. By using a FPGA in Cyclone III series from Altera as a platform, a SOPC containing several peripheral interfaces such as SRAM and W5300 is established. The video data are gathered by the TAU320 infrared camera and are ping-pong stored to a SRAM. Then, the data are read out in the DMA mode and are sent to a remote PC via a W5300 network chip. The client interface of the PC is used to control the hardware circuit and display the video data. Since the video data are transferred via TCP protocol, the proposed system has the features of small volume, low power consumption and flexible controlling.
