Question

3. (30 pts.) Implement the following ASM: Func(x, Y. Z, start, U, done) Input XIO:71, YIO:7. start: Output U[0:71 done: A[O:7], Registers B[0:7], C[0:7); i: If start' goto Si S2: A -XII BYI1C-(00000000)11 done c-0 S3: A <" Add (A, B) 11 C <" Inc (C); .S4: IE A' 71 goto S3 S5:U- CIl done <1 11 goto $1 end Func Design a datapath subsystem that is adequate to execute the algorithm. i. Use a table to list the instructions and corresponding components for data path subsystem. a. Control Signal Statement Operation A -Load (X) 1, C1 A<- A+B A<-Add (A, B) CO-0 Cl-1 ii.
