Design of Multi-channel PCI Data Acquisition System Based on the SOPC

In present industrial field, the high-speed data acquisition system with small size, high-accuracy and multi-gain choices is badly needed. This paper presents a realizing solution of a parallel PCI high-speed data acquisition system for universal multi-channel based on the SOPC. With this system, we can either use these 12 channels together or choose combination. Meanwhile, the gain-programmed amplifier can also be selected as well as difference or single-ended parallel input way. Also, the sampling rate of the multi-channel can reach at the same time up to 200KSa/s, and the vertical resolution of the high-accuracy PCI data acquisition module is 16bit.
