“A digital computer has three registers: A, B and C. Four flip-flops provide the control functions for the computer: S is a flip-flop that is enabled by an external signal to start the
system’s operation; L and R are used for sequencing the microoperations; A fourth flip-flop T is set by the computer when the operation is completed. The function of the system is described by the following register transfer statements:
S: C ← 0, S ← 0, T ← 0, L ← 1
L: L ← 0, if (A = 0) then (T ←1) else (R ← 1)
R: C ← C + B, A ← A – 1, R ← 0, L ← 1
Design a circuit with minimum components to implement the above operations.”
