Wireless data transceiving method and system

Abstract

The invention relates to the field of wireless communication and discloses a wireless data transceiving method and a wireless data transceiving system. In the method and the system, a direct memory access (DMA) in a processor caches data received from a wireless module in a memory and makes the processor process the data intermittently by interruption to reduce the power consumption of the processor and prolong the standby time of terminal equipment. The DMA in the wireless module is in a continuous working state to cache data to be transmitted which is from the processor to the memory and wake a sleeping wireless module processing core up by the interruption to perform centralized processing. The DMA continuously works to acquire the sleeping opportunity of a main part of the wireless module and the processor and greatly reduce the power consumption of the system on the whole.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to an energy-saving technology when a terminal surfs the Internet in a wireless manner. Background technique [0002] Electronic Ink is a revolutionary technology for displaying information. E-ink can maintain images for weeks without consuming any additional power, whereas other display technologies typically require constant power consumption while displaying. [0003] One application of e-ink is in the display screens of e-book readers. Utilizing the advantage that electronic ink can maintain images for a long time without consuming power, this kind of e-book reader only needs a small amount of power when turning pages, and a small lithium battery can turn tens of thousands of pages. Moreover, the reflectivity and contrast of electronic ink are better, so reading for a long time will not hurt your eyes. [0004] In order to facilitate users to obtain new e-books, some e-b...

Problems solved by technology

[0006] First of all, when data is received wirelessly, it is not received at a uniform speed, and its data rate fluctuates. Therefore, if the system is still running at full speed at a low speed, it will definitely cause waste of power consumption;

[0007] Second, even when receiving data at full speed, the data bus rate from the wireless module to the processor is limited, usually lower than the processor's internal bus rate, so in most cases the processor is waiting External bus data transmission, if the processor is still running at full speed at this time, power consumption will also be lost

[0008] For e-book readers using electronic ink technology, because of the low energy consumption of the main work (reading), the energy consumption of wireless Internet access will greatly reduce the number of times that the pages can be turned, which is equivalent to greatly shortening the standby time, and the problem is particularly serious
