Design and realization of the Multi-Channel Analyzer based on CPLD

This paper researches the hardware and software designing method of Multi-Channel Analyzer (MCA). The core of this paper has three parts: (1) introducing OrCAD/Pspice software to design the MCA circuit. The controlling circuit uses CPLD chip. It accords with our demand by testing, at the same time, this will expediently design circuit in the future; (2) using VxD(Virtual Device Driver) and VtoolsD in interrupt program, which is the key technology of interrupt design based on Windows 9x.; (3) introducing adaptive wavelet algorithm in data disposal. The test, results show that the MCA works in the course of nature and the software operates expediently.
