The FPGA integration rate is very high, its component density from tens of thousands of system gates to the number surely system gate different, may complete the extremely complex succession and the combinatory logic electric circuit function, is suitable high speed in, the high density high end numeral logic circuit design domain.The new FPGA scale is more and more big, the cost is more and more low.The high performance-to-price ratio causes the programmable logical component to act day by day the important role in the hardware design domain。More and more many will carry the FPGA product to contain processor essences high and so on the DSP or CPU, thus FPGA gradually will transit by the traditional hardware design method for the system-level designs the platform;FPGA and traditional ASIC further fuses, will contain the function more and more rich hard core (Hard IP Core) and speeds up the occupation part ASIC market through the structurized technology; The low cost FPGA density is more and more high, the price is more and more reasonable.Might foresee FPGA gradually to become the ideal first choice component which the complex digital circuit will design.Large capacity, high velocity FPGA appearance, has overcome AS1C design many insufficiencies.Large capacity, high velocity FPGA appearance, has overcome AS1C design many insufficiencies.Its is most greatly different lies in the FPGA design not to have the user special to have custom-made the production process, but is through downloads by the binary bit manifold type to the chip in carries on the disposition.In these FPGA, generally all in inlays high speed RAM, PLL, LVDS, LVTTL as well as which has may dispose DSP modules and so on hardware the multiplication accumulator……
