Fpga-based Pci Data Acquisition Card

Based on the analysis of PCI Specification, this paper has developed a PCI high-speed data acquirement system. The paper not only implements a 33M, 33 bit PCI protocol but also designs high-speed AID the circuit by using FPGA controlling which composes a data acquirement system, and develops device drives. Some advantages of the method which implement PCI bus and A/D control circuit using FPGA lie in flexible system, low cost, high reliability and high quality. This FPGA design introduces the method which is from top to button, describes the digital circuit using VHDL, synthesizes and emulates using EDA tools. So that we can complete complex design in short time by using these methods.
