Embodiment Construction

[0024] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0025] In order to solve the problem of delayed response of the embedded system, the present invention proposes a two-thread solution for the characteristics of the embedded system, specifically: including a key acquisition thread and a key processing thread, wherein the key acquisition thread is used for receiving and The button signal is saved, and the button processing thread is used to process the button signal transmitted by the button acquisition thread. During the button processing process of the button processing thread, the button signals received and saved by the button acquisition thread during this period of time are received and saved, and when the button processing thread is idle, all the saved button signals are transmitted to the button processing thread at one time. The thread is used for processing, which reduces the waiting time for the but...

Abstract

The invention discloses a method and a device for solving the delayed response of an embedded system comprising a keystroke acquisition thread and a keystroke processing thread, wherein, the keystrokeacquisition thread is used for receiving and storing a keystroke signal and transmitting the stored keystroke signal to the keystroke processing thread when the keystroke processing thread is in idleness; the keystroke processing thread is used for processing the keystroke signal transmitted by the keystroke acquisition thread and entering the idleness on condition that the processing for the current keystroke signal is finished and no new keystroke signal is transmitted. Application of the method described in the invention can solve the delay problem, relative to user, of the keystroke response program in the embedded system, enhance the performance of application products of the embedded system and promote user experience.

Description

technical field [0001] The invention relates to a solution method and device for delayed response of an embedded system, in particular to a solution method for delayed response of keys in an embedded system, and belongs to the technical field of embedded system applications. Background technique [0002] At present, embedded systems are widely used in consumer electronics fields such as set-top boxes, digital TV sets, and home network equipment. Compared with general-purpose computer systems, embedded systems have the advantages of strong professionalism, good real-time performance, and low power consumption. Since consumer electronics usually occupy more resources, the functions to be implemented are relatively powerful, while embedded system memory resources are limited and the CPU response speed is slow. Therefore, the button response speed of consumer electronics products with embedded systems is always slower than Insufficient user's button speed, especially when the u...
