ZR36050 - ETC

ZR36050 JPEG IMAGE COMPRESSION PROCESSOR

The ZR36050 is a high-speed JPEG Image Compression Processor that performs the algorithm specified by the JPEG Baseline and JPEG Lossless standards for high-quality image compression and expansion of continuous-tone color or monochrome images. The ZR36050 performs Discrete Cosine Transform (DCT), quantization and variable-length encoding for image compressio.

Features

s Implements JPEG Baseline image compression and expansion, including: - DCT/IDCT operations - Quantization - Variable length coding/decoding s Full support of the JPEG Baseline standard, including: - Bit and byte stuffing - JPEG markers including restart (RST), application (APP), and comment (COM) s JPEG Lossless compression and expansion s DMA/SLAVE bus interface s Motion video (30 frames/sec) compression/expansion capability for CCIR resolution (720 x 480) s “Fast Preview” option - Preview of “thumbnail” version of images (up to 25x faster) s Bit rate control option - Guarantees compressed i.
