Input I1, I2 and I3: Boolean values
Output (O): 24 bit integer value (packed boolean)
Arithmetic function
BITWISE
I1
I2
O
I3
The block compares bits of three 24 bit word inputs and forms the output bits as
follows:
O = (I1 OR I2) AND I3
Example
I1 I2 I3 O
0 0 0 0
0 1 0 0
1 0 0 0
1 1 0 0
0 0 1 0
0 1 1 1
1 0 1 1
1 1 1 1
Input I1: 24 bit integer value (packed boolean)
Input I2: 24 bit integer value (packed boolean)
Input I3: 24 bit integer value (packed boolean)
Output (O): 24 bit integer value (packed boolean)
