Abstract: Example graphics processing methods and apparatus are described. In one example method, the graphics processing apparatus includes a shader, a memory management unit, and a coprocessor connected between the shader and the memory management unit;. The shader is configured to send a read instruction to the memory management unit, where the read instruction includes an address of a first operand and a first identifier, and the first identifier indicates to perform an operation on the first operand in the coprocessor. The memory management device is configured to obtain the first operand from a first memory, and send the first operand to the coprocessor. The coprocessor is configured to perform the operation on the first operand to obtain an operation result.

Abstract: The present invention relates to touch screen technology, and provide a weight pressure process method and system of the self capacitive touch screen. In the weight pressure process method and system of the self capacitive touch screen provided by the invention, a threshold relationship is used to modify the existing touch threshold, the threshold relationship uses the touch threshold and the minor change of the changes of two channels adjacent to the channel corresponding to the maximum value as variables, if the maximum value is not greater than the value of the threshold relationship, identify the point causing the current change as a fake point and filter out the fake point. In the method, the change of the self capacitor caused by the deformation due to pressure, so the actual touch point can be identified more accurately, a touch application can be performed correctly, and the user experience is improved greatly.
