LC82220
Motion JPEG Decoder LSI
Preliminaly
Overview
The LC82220 is a single-chip JPEG decoder designed for
wide range of digital video playback applications
including amusement systems, video games and PC JPEG
playback cards. The LC82220 is capable of decoding
JPEG bitstreams of SIF resolution with a picture rate of 30
frames/sec. The digital video output can be formatted for
NTSC, PAL, SECAM, or any other optional video
standard. The complete decoding function is realised with
the LC82220, a standard 8-bit or 16-bit microcontroller
and a bank of DRAM. A typical memory configuration is
a single 128 k × 16 or 256 k × 16 DRAM. The LC82220
also supports efficient video display functions such as
scroll and overlay.
Functions
• Support for JPEG format
• Real-time decoding of motion-JPEG with rate of 30
frames/sec
• Lowest solution cost for amusement, game, PC
systems
• Support for YUV 4:1:1 color format
• YUV or RGB digital video outputs compatible with
optional video format
• Programmable picture and display window format
• Support for trick display: scrolling, overlaying
• Standard 8/16-bit microcontroller interface with DMA
support for compressed data input
• Support SOI and EOI markers
• Direct connect to video DAC
• Direct connect to 2 M or 4 M DRAM as bit and frame
buffers
• Two Q-tables included
• High-speed processing by fixed Huffman tables
