Vector Multiplication Unit (VMU)
Each VMU consists of three multipliers used for multiplying unsigned 8-bit pixel components with
signed 12-bit coefficients.The result from each multiplication is a 20-bit signed number that is
input to a 22-bit vector adder along with an offset as shown in Figure 8-2 on page 27. The oper-
ation is equal to the offsetted vector multiplication given in the following equation:
Figure 8-2.

∈ {0,1,2})

Input Pixel Selector
The Input Pixel Selector uses the ISM (Input Selection Mode) field in the CONFIG register and
the three input pixel source addresses given in the PICO operation instructions to decide which
pixels to select for inputs to the VMUs.
8.5.1
Transformation Mode
When the Input Selection Mode is set to Transformation Mode the input pixel source addresses
INx, INy and INz directly maps to three pixels in the INPIXn registers. These three pixels are
then input to each of the VMUs. The following expression then represents what is computed by
the VMUs in Transformation Mode:
8.5.2
Horizontal Filter Mode
In Horizontal Filter Mode the input pixel source addresses INx, INy and INz represents the base
pixel address of a pixel triplet. The pixel triplet {IN(x), IN(x+1), IN(x+2)} is input to VMU0, the
pixel triplet {IN(y), IN(y+1), IN(y+2)} is input to VMU1 and the pixel triplet {IN(z), IN(z+1), IN(z+2)}
