Portable computer peripheral equipment

Abstract

Peripheral device, in a portable computer casing, including an external package, at least one peripheral processor, in the external package, providing specific computing, control or driving functions, a clock circuit, in the external package and connected to the peripheral processor , generating a predetermined first frequency clock signal and transmitting it to the peripheral processor to make the peripheral processor operate according to the predetermined first operating speed, a temperature control circuit arranged in an external package, which has a temperature sensor. When the temperature detected by the temperature sensor of the temperature control circuit exceeds the first predetermined temperature, the first output is generated to the clock circuit to reduce the frequency of the generated clock signal to the predetermined second frequency, so that the peripheral processor reduces its operating speed to the predetermined frequency At the same time, an interrupt signal is generated to interrupt the operation of the central processing unit, so that the central processing unit executes a corresponding interrupt processing program to process the related actions after the peripheral processor reduces its operating speed.

Description

technical field [0001] The invention relates to a peripheral device of a portable computer, in particular to a peripheral device of a portable computer with a temperature control circuit. Background technique [0002] In today's society with advanced information technology, computer systems have already penetrated into various industries and become an indispensable part of informatization in all walks of life. With the increase in data storage density, increase in computing speed, and reduction in production costs, portable computers have become an important goal and mainstream in the development of the computer industry. [0003] For portable computers, heat dissipation is one of the main design points. On the whole, the source of heat is mainly from the central processing unit (CPU). Therefore, the design of heat dissipation in portable computers is mostly to solve the central processing unit The heat consumption of the processor dominates. With the improvement of the ov...

AI Technical Summary

Problems solved by technology

With the improvement of the overall performance of the system, many components will also increase with the increase of the computing speed of the central processing unit and the increase of the system temperature. If the heat dissipation design is not good, the system temperature will be overheated and the system will be unstable. Accidents that even cause injury due to system or component overheating

In addition, when some components continuously improve the maximum possible performance, the maximum heat consumption is also relatively increased, but in actual operation, this phenomenon is not easy to be noticed by users

When the temperature reaches the maximum allowable temperature that may affect the components, the system will appear unstable
