FPGA(Field Programmable Gate Array) is a programmable device with strong logical function and timing control ability.It is extremely potent in acquiring and processing timing signals.By replacing the traditional used SCM(Single-Chip Microcomputer) with FPGA

counting speed of Mssbauer spectrometric data acquisition can be improved markedly with significantly decreased size of the spectrometer.The counter

RAM and RS-232 communi-cation of the module are developed on Altera Cyclone series chip EP1C6T144C8 with Quartus Ⅱ.EP1C6T144C8 has 5980 logical units accompanied by 92160 bits of memory space.It is so powerful that all needs in data acquisition of the Mssbauer spectrometer can be perfectly satisfied while allowing modifications in functions and parameters.
