hey all,
i´m quite a beginner in digital design and i´d need some help with some system considerations. i work with a 100nm cmos process. and 1GHz sampling frequency
in my system i get the data out of 2 clocked registers which have 7 bit length.
i want to add the data of these registers with a digital adder.
as far as i know i need a register at the output of the adder so that the data is stored there.
but then this register will also be clocked and cause an additional delay.
am i right with the assumtion that without the register at the output data will not be stable?
the output data will be fed back into another system so that stable data during one clock cycle are required.
is there another possibility of adding without requireing an additional register?
how can i reduce the delay of this addition?
thanks all.
