Zusammenfassung:The invention provides an IEEE 1394b data transmission processing system based on FPGA, comprising an FPGA logical and control circuit, an IEEE 1394b controller circuit, a memory circuit, an external reset circuit and a clock circuit. The FPGA logical and control circuit integrates an embedded processor, a periphery component interconnect PCI interface controller, a memory interface controller, achip-on memory and a phase-locked loop controller. The embedded processor is connected with the PCI controller, the memory interface controller, the chip-on memory and the phase-locked controller by a bus; the PCI interface controller is connected with an IEEE 1394b controller and the clock circuit; the memory interface controller is connected with the memory circuit; the phase locked controller is connected with the clock circuit; the IEEE 1394b controller circuit is connected with an IEEE 1394b device and the clock circuit; and the external reset circuit is connected with the FPGA logical and control circuit.
