Graphic display controller with high-speed drawing of 60 frames per sec.

Description

ML511003 is the graphic and video display LSI for automotive onboard equipment with LCD. It has graphic drawing and TFT panel display functions, and also video interface and video processing functions. It can combine a graphic with the video taken in from the camera, and can display it on a liquid crystal panel.
An external memory is unnecessary due to the original architecture which processes by a line buffer without having a frame buffer, and high-speed drawing of 60 frames per second is possible. It has sufficient functions and performance for the information display equipments such as the automotive onboard meter or audio with the video display and the text display function.
Furthermore, we can supply the development environment including the authoring tool for the application software development which needs huge number of processes.
