Abstract
For its excellent performance compared with other cameras, GigE Vision cameras have been extensively applied in real-time image acquisition systems. But its features, such as the high CPU utilization and the dependency on network protocols, make it hard to be applied in embedded systems. This paper presents a hardware solution to access GigE Vision camera. It is a special Ethernet controller, which uses hardware logic to analyze network protocol as well as GigE Vision protocol, and can write image data into memory actively. Because the Ethernet controller is simplified and the protocols are analyzed by hardware, resource consumption and CPU utilization are both reduced. The experimental results prove that the CPU utilization of proposed solution is leading to zero, the acquisition speed of 1280 × 256 image is up to 228 frames per second, and the resource consumption is less than other solutions, which is only about 1393 logic unit blocks, 984 registers and 46,080 bits of memory.
