GENERAL DESCRIPTION
The ZR36011 Digital Color Space Convertor performs forward
or inverse conversions between RGB and YCbCr color spaces.
It is intended for use as a building block in systems that require
this function. The direction of the conversion (RGB to YCbCr or
YCbCr to RGB), and all other operating mode options, are deter-
mined by the states of control inputs. The 24-bit RGB and YCbCr
data buses are bidirectional, making for straightforward interfac-
ing when the direction of signal flow is reversible, as in a video
compression and expansion module. Conversion between
CyMaYe (Cyan, Magenta, Yellow) and YCbCr color spaces is
also supported. An additional conversion stage, between RGB
and CyMaYe color spaces, is inserted in this case, thus redefin-
ing the R, G, B pins as Cy, Ma, Ye.
The color space conversion coefficients are fixed. One of two
sets of coefficients can be selected: one suitable for component

signal ranges conforming to CCIR Recommendation 601, the
other for components occupying the full 8 bit numeric range.
Decimation and interpolation of the color difference signals is
supported. The available modes are 4:4:4 (undecimated), 4:2:2
and 4:1:1. Filtering is optional in the 4:2:2 mode, and is always
performed in the 4:1:1 mode. Other operating modes allow
simple two-to-one compression to be performed by an additional
decimation of the Y, Cb and Cr data, as well as the correspond-
ing decompression by interpolation.
A two-bit bidirectional shift register, with the same number of
stages (eight) as the computation pipeline, is provided. This can
be used as a delay line for synchronization signals, to keep them
synchronized with the data.
