基于FPGA与PCI总线的实时控制计算机的设计与实现

Design and realization of real time control computer based on FPGA and PCI bus

实时控制计算机(以下简称实控机)是工业设计中具有重要地位的一部分,承担着对整个系统的时序进行控制,或对其他各部件的工作进行指挥并获取其状态。本实控机将FPGA与单板计算机相结合,控制端利用单板计算机控制逻辑,利用PCI总线收发数据,与其他各部件的通信端采用8 Mbit/s同步串口完成通信。

Real time control computer （hereinafter referred to as the RTC） is of decisive importance in industrial design. It controls the sequential relationships of the whole system, or commands other parts and receives their status. The RTC is made up of one FPGA chip and one Single Board Computer. The control terminal is designed on the Single Board Computer in order to control logic and the data transmission is by PCI bus. The communication between RTC and any other part of the system is realized by using the 8 Mbit/s Synchronous Serial Port.
