Abstract

A method using SMBus chip to monitor component on AGP plate and its device, which relates to bus in computer and application of its chip. The method is extending SMBus node and using SMBus chip on AGP plate, to measure the parameters of figure processor such as voltage, speed of fan, temperature, using temperature as feedback signal input the monitoring chip and calculation and control of output, forming closed ring by controlling fan speed through magnifying driving circuit. The device comprises of monitoring chip on AGP plate, temperature sensor, magnifying driving circuit, fan, power source, circuit for measuring rotating speed, voltage dividing circuit. SMBus, fastener and radiating plate. It has the useful effect that the combinated monitoring AGP plate can measurement and control rotation of GPU cooling fan on the control plate, decrease noise, environmental protection and energy saving.

Description

technical field [0001] The invention relates to the expansion and application of the bus and its components in a computer, in particular to a method and device for monitoring the components on an AGP board with a system management bus (SMBus) integrated circuit chip. Background technique [0002] AGP AGP (Accelerated Graphics Port) graphics acceleration interface is a widely used display card interface technology, which can greatly improve the display capability of 3D graphics. Major display card manufacturers have launched a large number of AGP display card products, and there are many motherboards with AGP interface. According to There are AGPX1, AGPX2, AGPX4, AGPX8 specifications proposed successively. Although the graphics processing capability of PCs is getting stronger and stronger, the performance of the PC platform is still limited to complete detailed large-scale 3D graphics rendering. In order to make the 3D application capabilities of PCs comparable to graphics wo...
