General Description
The
transformations from one color space to another.
shows the members which make up the CS6400 family of
products. All members of the 6400 product family use 10-bit
coefficients in the core for all calculations with rounding
carried out at the outputs. All cores have both input and output

registers plus an additional pipeline cut allowing high speeds
to be achieved with a low latency of 3 clock cycles and a
throughput of 1 clock per cycle.
Figure 3 shows the internal operation of a generic converter.
Internal precision of 10 bits maintains accuracy of the 8 bit
output. Input and output colors as well as specific coefficient
values are given in Table 3.
