The SH7769 SoC enhances such functions as video input, display output and high-reliability systems compared to Renesas’ existing
SoC, which has been widely adopted for high-end automotive infotainment systems.
The SH7769 SoC implements a high-function 3D graphics engine and display units, which allow 1600 x 480-pixel HD (high definition) video decoding. In addition, up to three video data streams can be processed simultaneously to provide a driver with information from external vehicle cameras, navigation systems, and night vision devices at the same time. A function that flattens the distortion of a fish-eye image, and a function that transforms the image data into a given form, are also integrated.
