介绍了一种基于TMS320F2812的1024道脉冲幅度分析器。主要应用于核脉冲信号的能谱分析，下位机以DSP作为主要的信号处理器，并且通过自身的ADC对核脉冲信号进行数字化处理，通过数字算法将采集到的信号进行寻址、道址加一操作，对前面的操作进行循环，经过一段时间的积累，最后得到被测核脉冲信号的能谱，随即存储至DsP外部大容量Flash芯片中。通过实验测试，本系统能有效提高仪器精度，并且有很强的抗干扰能力。系统通过RS232最终将能谱上传至计算机，做进一步分析。

This paper introduce us a design of MCA based on TMS320F2812 with 1024 chanles.Mainly used in nuclear pulse signal spectrum analysis.The DSP to be used as a primary signal processor.The nulear signals be digitized by the ADC module inside of DSP.Then use the digital signal as a address to find the chanle address and make it plus one,repeat many times, after a period of time,then we got energy spectrum.When reach a certern time,we move it to flash out of the DSP.The system has high precision and strong anti-jamming capability.Use RS232 upload data to the computer to make further analysis.
