Embodiment Construction

[0020] A touch screen data processing system, a data processing method and a dedicated ALU provided by the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] figure 1 It is a structural block diagram of the touch screen data processing system according to the present invention, wherein:

[0022] [1] Open up a memory array space, which contains n unit memories M1, M2, ... Mn, any unit memory can store complete or part of the touch screen sampling data or intermediate calculation results of data processing; the unit memory can be a block An independent memory (such as SRAM, etc.) can also be a local space of a specified address area in a memory.

[0023] [2] ADC scans the touch screen, and stores the data obtained by one touch screen scan in a certain unit memory, such as M1, or stores the data obtained by multiple touch screen scans in multiple unit memories.

[0024] [3] The MCU sends special A...

Abstract

The invention discloses a capacitive touch screen data processing system. The capacitive touch screen data processing system comprises a memory array, a micro control unit (MCU) and a special arithmetic logic unit (ALU), wherein the memory array is provided with a plurality of unit memories, and any unit memory is used for storing the complete or a part of original sampling capacitance data or data processing operation results of a touch screen; the MCU is used for performing flow control, and transmitting a special ALU command to the special ALU; and the ALU is used for performing operation on the data in the memory array according to the special ALU command transmitted by the MCU, and storing the results in the memory array, wherein the special ALU command has the command format so that the ALU can finish the batch processing of a plurality of storage data in a special ALU command. The special ALU command which can process batch data and the special ALU for processing the special ALU command are used in the capacitive touch screen data processing system, so that the workload of the MCU can be reduced, and the operation efficiency is greatly improved.

Description

technical field [0001] The present invention relates to touch technology, in particular to a touch screen data processing system, a data processing method and a special arithmetic logic unit (ALU, Arithmetic Logic Unit) for the touch screen. Background technique [0002] The touch screen controller of the prior art needs to monitor the signals (such as capacitance, resistance, etc.) collected by the analog / digital converter (ADC, Analog-to-Digital Converter) in the touch screen system in real time, and convert them into digital signal form storage The original sampling data information, and then execute a special data processing algorithm through the micro control unit (MCU, Micro Control Unit), convert the original data into the information of the human body's touch position on the touch screen and report it to the system host. [0003] The workload of the MCU, or the requirement for the processing capability of the MCU, depends on the size of the original sampled data, the...
