High Speed Multi-channel Data Acquisition System and Storage System Based on PCI Bus

The paper first introduces principium and the developing actuality of data acquisition system about ICT.The authors then discuss PCI protocol and structure,function and work principle of the PCI bus controller S5933.Base on these,with the circuit design tools such as MAX+PLUSII,PROTEL 99SE and VHDL,etc.,the two types of high speed multi-channel data acquisition system based on PCI bus have been designed by using PASS-THRU channel and FIFO channel of S5933.

Data Acquisition System of PCI Bus Interface

After having studied the PCI bus and compared the capability, it is analyzed and compared in capability and cost and complexity of some kinds of application for data acquisition system, a high speed system which composed of chip S5933 and CPLD is designed.     

Study and Design on Teaching Experiment Instrument of CT Data Acquisition System Based on CPLD

The purpose of developing Teaching Experiment Instrument of CT is to demonstrate the whole process of CT scanning more intuitively, thereinto the design of data acquisition system is one of the emphases in the developing of the CT system. This paper mainly introduces the design and implement of the data acquisition system of CD - 50BG, using CPLD apparatus which have the characteristic of high integration, in the design of data acquisition system to achieve the target of minishing system bulk and improving system reliability. Aiming at the data loss of CD - 50BG during acquiring data, the data acquisition system is reformatively redesigned, the data loss in the high speed data acquisition process is reduced so that the stability of transmission has been improved by using FIFO.
