According to the disadvantage of the large noises of histogram equalization algorithm  a new adaptive image enhancement algorithm is presented. First  the statistical histogram of the infrared image is done. Then the threshold of plateaus Equalization is calculated and the statistical histogram is modified. Finally the bright values of the pixels of the image are changed. An embedded high speed image enhancement processing system on high performance DSP TMS320DM642 and FPGA was designed. Experimental results with real images shown that the system can improve the contrast of the infrared image  limit the noises of the enhancement image  and effectively enhance the infrared image  the running time of the program is shorter  so it can meet the requirements of real-time in the project.

In order to increase the transmission distance and reduce noise effectively  a communication system with the optical fiber interface is developed in this paper. In the system  the PCI bus is adopted as the connection bus between the underlying optical fiber transceiver module circuitry and host computer using the WDM driver. The FPGA is the core logic of the whole system  responsible for data transmission and timing logic control. The module structure and the design method of the PCI bus  the principle and the design of optical interface module and the bottom-driven development are described in this paper. The experiment results show that the system has basically meet requirement targets. It can achieve the maximum transfer rate of 40MBps when running in the DMA mode. With long transmission distance  strong antiinterference and high scalability  this system has stable and reliable performance. 2010 IEEE.
