A High-speed Pci-based Dsp Data Processing System

Based on the item "HJ-1A hyperspectral payload real-time data processing module spectrum recovery," the follow-up study.Through independent development of high-speed PCI-based DSP data card, To complete the image of rapid real-time data processing, and the establishment of the algorithm to match the ground hardware platform for data recovery.The article discussed the system in the hardware and software parts . Hardware circuit to DSP as the core, FPGA logic circuits, PCI interface circuits, and so on. The software system design, the main DSP design process, PC-to receive real-time image processing, real-time processing is the core of the whole system."Based on the PCI Express DSP data-processing system," using TI's C6701 DSP to achieve processing, and high-speed massive data processing complex, the choice of achieving S5933 mass of high-speed data transmission to match completed "HJ-1A hyperspectral payload real-time data Spectrum recovery processing module "on the ground related hardware platformSampling the entire system of logic control in part by a FPGA chip, the FPGA with high-speed, high reliability, short development cycle characteristics, and under the specific needs of online programming (ISP), can erase many times, so they have a very Great convenience. With specific applications, given the acquisition process and some control circuit. And PCI bus on how to achieve real-time transmission of image data made some explorationDriver access and control hardware as the software interface into the computer operating system is a part of it relates to the core Windows programming technology, also requires knowledge of hardware designers have a certain understanding. Finally, some gave a briefing on how the environment in the development of equipment Windows2000 bottom drivers...
