Overview
The LC8220 JPEG LSI implements digital still image
compression and decompression conforming to the JPEG
(Joint Photographic Expert Group) standard. The LC8220
includes the baseline system of the ISO 10918 (JPEG)
standard, and requires no external components to construct
an application that performs JPEG compliant
compression/decompression.
Features
Conforms to the ISO 10918-1 baseline system
Four quantization tables and four Huffman tables (two
for AC and two for DC) are built in.
Hardware support for JPEG marker codes
Built-in bidirectional YUV - RGB converter
Many color component sampling ratios are supported.
(e.g., YUV 4:1:1 and YMCK 1:1:1:1, etc.)
Level shift function that can be defined for each
component
Built-in dual buffers for reduced data transfer load
Bus sizing function that allows direct connection to 8-,
16-, and 32-bit busses
Endian control function
Three independent data buses
