Problem - O/p labeling convention in Moore control FSM states: signals not specified in a state are inactive)

Problem 1: Consider the above data path and Moore control FSM for pipelined operation with a throughput of 1 output per 3 cc's in steady state, done in class. Modify the datapath and control FSM so that only one adder is used (the adder needs to be shared among the 2 add operations) and still run at the rate of 1 output per 3 cc's in steady state.

Hint: (1) need to use input muxes (controlled by the fsm) to the single adder to get the different inputs at different times for the 2 adds. (2) Both adds need to be completed within the 3-cc delay window available to each pipeline stage (the 2 adds in a single adder will be one pipeline stage).

(2) Need temporary register(s) that do not directly feed the multiplier but instead feed rl and/or r2 registers to store add outputs that are obtained in less than the 3 cc window as these o/ps should not change multiplier inputs for 3 cc's (after the previous load if r1, r2).

(3) It is ok for some regs to have junk data before steady state is reached (this is so in the original design above), but final o/ps in r4 starting from the r valid one have to be correct.

(4) Show the new FSM with the extra control signals needed (along with the original ones) with the RTL specified for each state (except those that a purely NOP). Also label the new control signals clearly in the new datapath.
