Symbol
When reading from the
Multiplier, the time from the
active transition at the C
clock input to data
appearing at the P outputs
Time from the setup of data
at the A and B inputs to the
active transition at the C
input of the Multiplier
Time from the active
transition at the Multiplier’s
C input to the point where
data is last held at the A
and B inputs
The time it takes for data to travel from the A and B
inputs to the P outputs
