In this paper

a reconfigurable computing platform based on PCI bus and multi-FPGAs is presented. The PCI bus interface is completed by chip PCI905 4. The configuration of bridge FPGA is employed to achieve data communication between computer FPGAs and the computer. Two computer FPGAs are used to parallel process data. The configuration of bridge FPGA is flexible and easy to expand more computer FPGAs. Parallel data processing is efficient in computer FPGAs

the design of algorithm is good for universal application. The speed of data transmission between computer FPGAs and the computer is at least 40Mb/s and actually the data throughput of computer FPGAs is 1.28Gb. So the platform is suitable for video and audio compression

data encryption and deryption

and other compute-intensive algorithms.
