Fast inking a touch display

A method for fast inking a touch display, comprising:

• receiving touch input a touch display;
• generating touch sensor data from the touch input;
• transmitting human interface device (HID) data generated from the touch sensor data in a graphics processing unit (GPU) to a writing application memory and a fast inker;
• converting, in the fast inker, the HID data into inking data;
• sending the inking data from the fast inker to a display pipeline through a direct hardware path intercepting a next frame in transit;
• converting, in the writing application memory, the HID data into inking data for a display screen;
• composing, with an operating system, the display screen from the writing application memory inking data and send the display screen to the display pipeline;
• displaying pixels marked by the display pipeline on the touch display based on the inking;
• storing a fast inking array of coordinates to correspond to the display pixels, the fast inker to mark the fast inking array of coordinates to correspond to HID data for both an inking time duration and a frequency touch input is received;
• and
• replacing the inking data with the display screen received by the display pipeline.

An apparatus for fast inking a touch display, comprising:

• a graphics processing unit (GPU) comprising a fast inker and a display pipeline;
• the GPU to transmit human interface device (HID) data generated from touch sensor data to a writing application memory and the fast inker;
• the fast inker to convert the HID data into inking data to be sent to the display pipeline through a direct hardware path
• the writing application memory to convert the HID data into inking data to be sent to the display pipeline;
• and
• the fast inker to mark a fast inking array of coordinates to correspond to HID data for both an inking time duration and a frequency touch input is received.
