Communication system implementing low-power consumption

Abstract

The invention discloses a communication system for realizing low power consumption. Main module of the system is connected with slave module by single bus, slave module receives close command main module has transmitted and closes interior unnecessary work parts, main module also interior unnecessary work parts after transmitting close command. In the invention a module closes only part and simply reduces system power consumption under condition of saving IO resource.

Description

technical field [0001] The invention relates to communication technology, in particular to a communication system for realizing low power consumption. Background technique [0002] In today's energy shortage, realizing low power consumption has become one of the priority issues in the design of communication equipment, and its common method is to turn off the power supply of the modules that are not working in the communication equipment. However, this method is not applicable in some cases, and a brief description will be given below taking a mobile communication terminal as an example. [0003] figure 1 It is a schematic structural diagram of a system composed of a main control module and an Enhanced Data Rate for GSM Evolution (EDGE, Enhanced Data Rate for GSM Evolution) module in the prior art mobile communication terminal, wherein the main control module is the general control module in the mobile communication terminal . The main control module includes: a first com...

Problems solved by technology

[0009] Although the above technical solution provides a solution for only turning off a part of a module to reduce power consumption, there is often a situation in the communication system where one host controls multiple clients. At this time, if this technical solution is used, each The client adds a gating channel respectively, and respectively adds corresponding devices used in conjunction with the gating channel in the host 100a and the client 200a, forming the following image 3 The structure shown in this way, the increased multiple strobe channels will consume more I / O port resources on the host

On the other hand, when a host controls multiple clients, the power-saving identifier sent by the host should indicate which client it is aimed at. Usually, in this case, different data combinations will be used to identify different clients. Due to the increased The strobe channel can only use simple high and low levels to represent logic 1 and 0. When continuous high levels appear, it cannot be recognized that the continuous high levels represent several logic 1s. When continuous low levels appear, there will also be The same problem, so the power saving identifier can only be sent through the data channel, that is, in order to achieve the purpose of reducing power consumption, the gating channel and the data channel must be required to participate at the same time, and the implementation process is more cumbersome
