Based On The PCI Bus Signal Processor Design And Implementation

Because the general signal processing system based on PCI bus making use of advantages of the DSP and PCI bus, can meet the high level demands of the radar signal processing and data transfer ability, so it's application in radar system are developed rapidly.But the general signal processing system based on PCI bus can not meet the size demand of the LFMCW radar system miniaturization. So development of the LFMCW radar signal processing system based on the embedded PCI bus is necessary; Designing special PCI bus interface, not only meet the system control,data transfer requirement of the SAR raw-data simulation system, but also make the system general.In the thesis, based on design and implementation of the two signal processing system of different requirement, Multi-DSP processor structure, DSP-PCI Interface, system control logic, PCI device driver program, user application program are researched. The main content is list as follows:1) According to the LFMCW radar signal processing algorithm, a signal processing system based on PC104-PlUS bus is developed. Accomplishing the system design,hardware implementation and test;2) According to the simulation algorithm of the SAR raw-data simulation system, Accomplishing the design and simulator of the system's DSP-PCI bus interface.3) Accomplishing the development of the driver programs for two signal processing board.4) Accomplishing the user application of the SAR raw-data simulation system.
