自动化专业外文翻译----基于嵌入式处理器的vlsi芯片的温度自动控制.doc

This paper presents embedded processor based automatic temperature control of VLSI chips, using temperature sensor LM35 and ARM processor LPC2378. Due to the very high packing density, VLSI chips get heated very soon and if not cooled properly, the performance is very much affected. In the present work, the sensor which is kept very near proximity to the IC will sense the temperature and the speed of the fan arranged near to the IC is controlled based on the PWM signal generated by the ARM processor. A buzzer is also provided with the hardware, to indicate either the failure of the fan or overheating of the IC. The entire process is achieved by developing a suitable embedded C program.

Keywords: Temperature sensor, ARM processor, VLSI chips, Brushless DC motor

本文介绍了基于嵌入式处理器的VLSI芯片的温度自动控制，同时利用温度传感器LM35和ARM处理器LPC2378来完成设计。由于VLSI芯片密度非常高，同时芯片在工作时很快得到加热，如果不能研制出能是它快速冷却的方法，芯片的性能将会受到很大影响。在目前的工作中，将传感器放置在非常接近接近到IC集成电路的位置来采集芯片的温度，通过由ARM处理器产生的PWM信号来控制集成电路旁风扇的转速。在硬件电路中也提供了一个蜂鸣器，在无法控制风扇或者IC集成电路的过热的情况下都会发出警报。整个过程的实现需要制定一个合适的嵌入式C程序。
