Integrated Color Space / Raster-to-block Converter

The ZR36016 is a pre- and post-processor for use with a ZR36050 JPEG Image Codec, performing raster-to-block reor- dering and color space conversion. The ZR36016 accepts input pixels in a variety of common color spaces. The pixel data CAN undergo format and color space con- version, with converted data available on the pixel output bus (Figure 1). When compressing, the data fed to the ZR36050 CAN be cropped within a selected window area, and its format CAN be different from that of the pixel output bus. For instance, it is possible to output an RGB(4:4:4) input onto the pixel output bus and to feed the ZR36050 with a YbCr(4:2:2) format. It is also possible to output a YCbCr(4:2:2) format input as RGB(4:4:4) and to feed the ZR36050 with a YCbCr(4:1:1) format. During expansion, for instance, the ZR36016 CAN output an RGB(4:4:4) input directly onto the output pixel bus, and after converting YCb- Cr(4:2:2) format coming from the ZR36050 into RGB(4:4:4), it overlays it in a window on the pixel input data. The ZR36016 uses an external SRAM double-strip Buffer for raster-block conversions and block interleaving. The Fast Preview and Lossless modes of operation of the ZR36050 are also supported, in which case the SRAM is used only for raster- to-raster buffering and pixel interleaving. Depending on the SRAM size and the mode of operation, the maximum line length CAN be up to 64K pixels. The number of lines per image CAN be up to 64K. By Unkown
