SPCA554A Mobile CameraSPCA554A Mobile Camera
Multimedia Processor By Harrison Tsou
Introduction 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.
