PCI Express is rapidly establishing itself as the successor to PCI, which provides higher performance, increased flexibility, and scalability for next-generation systems. FPGA offers a flexible solution for PCI Express compared with ASIC. Using IP Core and designing a DMA module in FPGA, this paper implemented a high-performance PCI Express system. IP Core handles the protocols defined by PCI Express specification. DMA module accelerates the transmission between FPGA and PC memory, sufficiently exploiting PCI Express bus bandwidth. This article proposes and achieves a PCI Express system having DMA transfer ability and emphatically describes the design of the DMA engine in system-logic, in addition to the corresponding Windows WDM driver and GUI application. The result of performance test is presented finally.

The design parameters and the operational aspects of mine water disposal project in Fengxi Xinyu coal mine were introduced. The primary disposal process included neutralization, coagulation settling and mechanical filtration process, and reverse osmosis (RO) process for desalination were used to treat mine water with high-turbidity, high-hardness and high-salinity. The results showed that the pretreated mine water could be used for washing coal, and the quality of permeate liquid of RO for water with milk excelled the national standards for drinking water. New water source was supplied to the coal mine, the recycle of mine water was resource engineering practice.

A series of experiments were performed to remove toluene from a gaseous influent at normal temperature and atmospheric pressure by non-thermal plasma generated dielectric barrier discharge coupled with nano-Ba0.8Sr0.2Zr0.1Ti0.9 O-3 catalyst. We were innovative to prepare nano-Ba0.8Sr0.2Zr0.1 Ti0.9O3 catalyst by ourselves and use it in the plasma reactor. The best removal efficiency of toluene arrives at 95% in condition of toluene concentration of 600 mg/m(3), flow rate of 1 mL/min and electric field strength of 14 kV/cm. Nano-Ba0.8Sr0.2Zr0.1Ti0.9O3 not only resulted in greater enhancement of toluene removal efficiency and reducing energy efficacy on treating with the same quantity of toluene, but also controlled byproducts effectively in plasma process.

Research on inter-prediction algorithms is an important respect in the real-time video codec *** the regarded studies,the prediction error can be reduced by incorporating high accuracy estimation and compensation *** the performance of compressed video can be ***,this brings a considerable cost for the complexity of *** computation complexity is mainly due to the complexity of motion *** paper presents an improved algorithm with the initialized searching point prediction,half-stop principle,beforehand skip mode decision,reduced search window and optional search *** algorithm for the integer-pixel motion estimation is provided to reduce computation complexity in the blockmatching *** results show that the proposed algorithm can reduce about 64%-73% of computation complexity compared to full search but only with little PSNR degradation.
