(b) Pre gain block
This block performs multiplication processing independently for ports 1 and 2. The settings are as follows.
Coefficient: 8 bits
Gain setting: 0 to 1.9921875 (= 255/128) times, variable in 256 steps
(Set independently for R, G and B ports 1 and 2)
Multiplication is performed using the 8-bit input and an 8-bit coefficient, and the upper 10 bits c[15:6] of the
operation results are output. Next, the c[6] value is checked and rounding is performed to 9 bits. The MSB of
the rounded 9 bits is checked, clipping is performed, and the lower 8 bits are output.

(c) Pre bright block
This block performs addition and subtraction processing independently for ports 1 and 2. The settings are as
follows.
Coefficient: 5 bits with code, MSB = code bit
Bright setting:
–
16 to +15 scales, variable with an accuracy of 1 bit
(Set independently for R, G and B ports 1 and 2)
Multiplication is performed using the 8-bit input and a 5-bit coefficient with code. The coefficient MSB is the
code bit. Addition is performed when b[4] = 0, and subtraction when b[4] = 1. However, when performing
subtraction, set the two's complement in the lower bits of the coefficient. When the operation results overflow
or underflow, clipping is performed.

(d) User gain block
This block performs multiplication processing independently for ports 1 and 2. The settings are as follows.
Coefficient: 8 bits
Gain setting: 0 to 7.96875 (= 255/32) times, variable in 256 steps
(Settings shared by R, G and B)
Multiplication is performed using the 8-bit input and an 8-bit coefficient, and the upper 12 bits c[15:4] of the
operation results are output. Next, the c[4] value is checked and rounding is performed to 11 bits. The MSB of
the rounded 11 bits is checked, clipping is performed, and the lower 10 bits are output.
