SPCA554A Mobile Camera Multimedia Processor By Harrison Tsou

Introduction SPCA554A is a multimedia processor targeting at mobile applications. It integrates a digital still camera processor, a MPEG4/JPEG CODEC engine, a 2D graphics engine and a rich set of peripherals. The powerful all-in-one functions of SPCA554A make the implementation of multimedia mobile applications much easier than before.
