Research On The Basis Of PCI Bus High-speed Data Collecting System

In recent years, based on PCI bus high-speed data collecting system is a developing direction of data gather and transmission technology. Because of PCI bus has a series of merits, application in a lot of fields PCI bus is becoming the standard in fact. This text regarded some key technology in the data collecting system at a high speed based on PCI as the research object, and has done the work of the following aspects.I have proposed two kinds of systematic schemes of interface: one is composed of a high-speed and high-accuracy A/D transition chip, a High-performance DSP chip and the PCI bus interface; the other is composed of a high speed and high-accuracy A/D transition chip, a MCU, a dual port RAM and the PCI bus interface. I have compared the advantages and disadvantages of these two kinds of schemes, and have confirmed with the data collecting system scheme including an ADuC812, a dual port RAM and the PCI9052 according to the actual conditions of the teaching and research room. I enumerated several popular PCI interface method at present and chose the PCI9052 as interface chip of system.This text has recommended the concrete actualized of the software and the hardware composed of an ADuC812, a dual port RAM, the CPLD and the PCI9052 data collecting system in detail. Hardware has narrated concretely system each function, implementation method and joining each other of module. Software has given course and main point of procedure making driver especially, and utilized SDK tool of PLX Company make application software of developing in detail.
