Control system and method for capacitive touch screen

A control system for a capacitive touch screen, comprising:

• a touch detecting circuit, for detecting a capacitance variance of the capacitive touch screen to generate a touch data;
• a plurality of touch hard instruction circuits, for respectively executing a touch computing function on the touch data correspondingly;
• a storage module, connected to the touch detecting circuit and the plurality of touch hard instruction circuits, for recording the touch data generated by the touch detecting circuit and the touch data computed by the plurality of touch hard instruction circuits, wherein the storage module is divided into a plurality of banks using a touch frame as a unit, so as to respectively record the touch data of the touch frame;
• and
• a controller, connected to the touch detecting circuit, the plurality of touch hard instruction circuits, and the storage module, for assigning at least one touch task of a touch algorithm to the plurality of touch hard instruction circuits, so as to execute a touch computing function of the touch algorithm correspondingly, wherein the touch detecting circuit, the plurality of touch hard instruction circuits, the controller, and the storage module are connected by a memory arbiter.
