The Electronic System Design Based On FPGA Re-configuration

FPGA can be solved not only the miniaturization of electronic systems, low power consumption, high reliability, and so on. And the application of FPGA shortening the development cycle, a reduce the software development Cost, also the prices of the chip become more Cheaper, more and more FPGA to replace the ASIC's market, in particular of small-volume, multi-species product demand, so that as the preferred FPGA.Using applied example, the technology of FPGA circuit reconfiguration was introduced in detail in this paper. According to fully understanding PS configuration timing,AT89C51 simulates and realizes PS configuration timing, and the system realizes the technology of FPGA circuit reconfiguration .Detailed system hard ward circuit diagrams and MCU program flow chart are provided in this paper. To show the technology of circuit reconfiguration, via two switches, we can select two different system architectures of the System. The figures are electronic clock and electronic answer devices, and thus to achieve a system of reconfigurable hardware.Reconfigurable FPGA technology from the traditional pursuit of large-scale, turn up to increase the utilization of resources. The logic of the new system while away the original system as a whole function, but in terms of resource utilization, can be repeated as a result of the use of resources to achieve the required system significantly decreased the size of the hardware.
