Design And Implementation Of Acquisition And Display Modules Based On Signal Processing Board

High Speed Signal Acquisition and Display Technology plays the key role in the digital signal processing. The performance of signal acquisition can affect the overall performance of the system. The system can display analog signal wave directly by using LSIC(Large Scale Integration Circuits), DSP(Digital Signal Processor) and LCD(Liquid Crystal Display).This technology can analyzes and processes analog signals easily.The design and implememat of this high speed signal acquisition and display system is discussed in detailed in the dissertation, The system in the thesis has the compact architecture built with DSP and FPGA(Field Programmable Gate Array). The embedded processor TMS320C6713B of TI company controls the whole system, which is in charge of the whole data processing synchronously.The FPGA of Altera company is the important part in the work, because they control many functional modules such as a controller of LCD display by EP2CS35F484, a controller of AD9244 by EP2CS90F1020.The signal acquisition part includes FPGA and AD9244, the logic of FPGA generates the double buffers to alternate signal, because the DSP and A/D chip's working speed can not match. This way can collect more data as far as possible.The dissertation emphasize on the way of implememation of the high speed signal acquisition and display system.The system applys two kinds of high speed signal processors. Because the CPU and memory are generated by FPGA, the logic can be changed for other needs flexibility.The thesis discusses the design of system structure and the program of DSP and FPGA's software mainly.In the software, data acquisition procedure is compiled by VHDL language and display console is developed by DSP etc.Finally the experiment results prove the feasibility of the system.
