Abstract: A low-power image capture device includes a first image buffer in SRAM coupled to receive images from an image sensor, and a second image buffer receiving images transferred in bursts from the first image buffer, the second image buffer implemented in PASR DRAM, the image buffers together operating as a first-in, first-out, (FIFO) buffer. The device includes an activation detector. The PASR DRAM is powered while receiving bursts of images from the first image buffer, and when the image capture device is in the activated mode; and in ultra-low power PASR mode otherwise. A method includes capturing images into the first image buffer, transferring the images in bursts into a second image buffer in PASR DRAM powered while receiving the images in bursts, the PASR DRAM otherwise in ultra-low power PASR mode; and, upon activating, an image processor receiving images from the second image buffer.

Abstract: An apparatus for driving an in-cell touch display panel includes: at least one line buffer configured to store display data; a display driver configured to receive display data from the at least one line buffer and drive a display module based on the display data; a touch controller configured to control a touch sensor to sense touching from a user; a time multiplex controller connected with the at least one line buffer, the display driver and the touch controller; and a host processor connected with the time multiplex controller and the at least one line buffer, and configured to generate display data and send the display data to the at least one line buffer. A method for driving an in-cell touch display panel is also provided.
