LC8220
JPEG Still Color Image
Compression/Decompression LSI
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
