DESCRIPTION
The ZR36016 is a pre- and post-processor for use with a ZR36050 JPEG Image Codec, performing raster-to-block reordering and color space conversion.
FEATURES
■ Raster-to-block and block-to-raster conversions with strip buffer of external SRAMs.
■ Color space conversions of RGB to/from YCbCr or YeMaCy.
■ Supports Fast Preview expansion and Lossless Compression/Expansion modes of the ZR36050.
■ Exclusive dual pixel buses. Separate format and color space conversions on the ZR36050 data and output data during compression and expansion.
■ Supports 4:4:4, 4:4:4:4, 4:2:2, 4:1:1 and 1:0:0 I/O formats.
■ Supports many format conversions between pixel input bus and pixel output bus, pixel input bus and ZR36050, and ZR36050 and pixel output bus.
■ Supports filtering for image format conversions.
■ Horizontal decimation/interpolation with optional filtering and vertical decimation/interpolation by line dropping or replication.
■ Enable function of pixel I/O buses for asynchronous applications.
■ Sequential processing mode simplifies motion JPEG implementation.
■ Provides windowing function to select processing area.
■ TTL levels for Input/Output.
■ 160 pin PQFP.
