Parameter
Description
C_OPERATION
The vector operation to perform. The supported operations are:
“and”, “or”, “xor”, “not”
C_SIZE
The size of the vectors. Notice that the width of Op1, Op2 and Res must be
equal. The minimum value of this parameter is 1.
Allowable Parameter Combinations
There are no restrictions on allowed parameter combinations for this core.
