PCI bus controller based on FPGA and control method

Abstract

The invention discloses a PCI bus controller based on an FPGA and a control method. The PCI bus controller comprises a PCI controller, a memory and a connected monitoring module. The PCI controller comprises a plurality of interfaces and is connected with external equipment and a local processor through the interfaces respectively; the memory is used for caching the interaction data of each external device and the feedback signal of the PCI controller; the monitoring module is used for detecting real-time temperature data, transmitting the temperature data to the PCI controller for processing,and triggering the PCI controller to call a locally stored audio file for playing reminding when the temperature exceeds a set threshold value; the beneficial effects are that the corresponding monitoring modules are integrated to monitor the real-time temperature, and when the temperature is abnormal, the corresponding audio files are triggered to be called, so that related personnel are reminded, and the damage probability of related parts is reduced.

Description

technical field [0001] The invention relates to the technical field of PCI bus control, in particular to an FPGA-based PCI bus controller and a control method. Background technique [0002] PCI is the abbreviation of Peripheral Component Interconnect (Peripheral Component Interconnect Standard), which directly hangs high-bandwidth peripheral devices on the CPU bus, so that the performance of the CPU can be fully utilized. With the continuous development of applications, more and more peripheral devices are mounted, and its processing load continues to increase, so that its controller is in high-load operation for a long time, and related devices are always stored in a limited space. However, when the temperature is too high or abnormal, the relevant personnel cannot be reminded in time, resulting in the sudden stop of the equipment and the damage of related components. Contents of the invention [0003] The object of the present invention is to provide an FPGA-based PCI b...
