SAA8122A Datasheet | Philips Semiconductors

Digital Still Camera Processor (Imag IC family) Rev. 01 - 20 April 2000 Objective specification 1. Description The DSC SAA8122A is a high performance, low power, single-chip Million Instructions Per Second (MIPS) based signal processor, part of the Imag IC family, which is dedicated to image processing, pression, formatting and storage. The DSC SAA8122A is optimized for use with Philips range of CCDs (e.g: FXA1022, 2 Mpixels CCD), V-driver (TDA9991), CDS/PGA/ADC (TDA9952), allowing easy implementation of a plete system solution and fast development of high performance consumer digital still cameras. The SAA8122A is designed as a single-chip device, able to perform all treatments and connections required for a wide range of Digital Still Cameras. Its embedded RISC CPU, for which the development environment is available, enables shorter development and validation cycles, as well as faster feature upgrade. Since one of the main objectives of the SAA8122A is addressing a wide range of CCD sensors, a DSP (with advanced embedded algorithm) for camera signal processing is integrated with a high level of programmability for pulses generation. The JPEG core is hardware based in order to allow high-speed image data pression. c 2.
