Data hierarchical compression transmission method, and device and electronic device for realizing method

Abstract

The invention relates to a data hierarchical compression transmission method, and a device and an electronic device for realizing the method. The method comprises: setting Z data thresholds, and setting a threshold interval code for each threshold interval; replacing the numerical value of each data word with a threshold interval code of the threshold interval where the numerical value of the dataword is located according to the threshold interval where the numerical value of the data word is located to form an interval code data word; combining threshold interval codes of more than two interval code data words into a compressed data word; and transmitting a compressed transmission data frame composed of the compressed data words to the main device, and decompressing the compressed transmission data frame into interval code data words by the main device. According to the method, the feature points of the transmission data are reserved through multi-order threshold quantization, the number of the data values of the data words is greatly reduced under the condition that the requirement for the report rate is not affected, it is ensured that the data volume of the transmission data is compressed by combining the multiple data words without distortion, and the compression rate is high.

Description

Technical field [0001] The present invention relates to a data processing method and a device and equipment for completing the data processing method, in particular to a method for data compression transmission and a device and equipment for completing the method. Background technique [0002] Abbreviated as I 2 The communication mode of Inter-Integrated Circuit bus in the integrated circuit of C bus is widely used because of its easy implementation. However, the prior art adopts I 2 One of the shortcomings of the C bus communication method is to limit the data transfer rate. For example, when I 2 When C bus communication mode transmits touch panel Touch Panel data, the touch panel Touch Panel is referred to as TP, I 2 The rate specified by the C bus communication protocol is 100kbit / s to 400kbit / s, and the TP data reporting rate requires 120 frames / s, so the time to transmit one frame of TP data is about 8.33ms. For a frame of TP data report, the algorithm itself takes about 5ms...

Problems solved by technology

When this problem occurs, the prior art should increase the length of the data buffer Buffer, which means that the above I 2 The time that the C bus can provide for reporting TP data is 8.33ms, which is not enough to complete the reporting of TP data, and the reporting time needs to be extended. However, this processing method in the prior art will cause a sudden drop in the reporting rate, which directly affects the user's experience. TP operation experience, the higher the report rate, the smoother the user experience TP operation, the user experience of the sudden drop in the report rate is that the TP operation fluency is poor, and even causes the TP operation to feel frustrated and lagging

Therefore, prior art I 2 C bus data transmission has defects in the computing power of embedded systems, such as precision requirements, poor graphics computing power, small memory, etc. There is no better way to transfer computing power, which limits the technical extension of many touch detection applications.
