Input
Yes
Yes
No
The
datab[]
signal is compared to this value. This port is
LPM_WIDTH
wide.
Value to be compared to
dataa[]
. This port is
LPM_WIDTH
wide.
Clock for pipelined usage. The
clock
port provides pipelined operation for
lpm_compare
. For
LPM_PIPELINE
values other than 0 (default value), the
clock
port must be connected.
Asynchronous clear for pipelined usage. The pipeline initializes to undefined.
The
aclr
port can be used at any time to reset the pipeline to all 0s,
asynchronously to
clock
.
