Algorithm Implementation for Sequential Process Execution

"This algorithm guides the sequential process execution based on input decoding, logical operations, and control flow. It includes steps for decoding operations, destinations, digits, and executing conditions. Register sizes and control signals are crucial for circuit operation."

  1. Solution to Exercise 8

  2. The algorithm • I == 0 : Op  Decode_Op(TerminalInput)I == 1 : Dest  Decode_Dest(TerminalInput)I == 2 : Dig1  Decode_Digit(TerminalInput)I == 3 : Dig2  Decode_Digit(TerminalInput) • If Op == ‘e’ E  0 • Tmp TerminalInput, I = I+1 • (I == 3) && Tmp == 20h (space): • Reg[Dest]  Op(Reg[Dest],Dig1) • I = 0 (I==4): • Reg[Dest]  Op(Dig1,Dig2) • I = 0

  3. The algorithm • I == 0 : Op  Decode_Op(TerminalInput)I == 1 : Dest  Decode_Dest(TerminalInput)I == 2 : Dig1  Decode_Digit(TerminalInput)I == 3 : Dig2  Decode_Digit(TerminalInput) • If Op == ‘e’ E  0 • Tmp TerminalInput, I = I+1 • (I == 3) && Tmp == 20h (space): • Reg[Dest]  Op(Reg[Dest],Dig1) • I = 0 (I==4): • Reg[Dest]  Op(Dig1,Dig2) • I = 0 Execute ifCondition

  4. The algorithm • I == 0 : Op  Decode_Op(TerminalInput)I == 1 : Dest  Decode_Dest(TerminalInput)I == 2 : Dig1  Decode_Digit(TerminalInput)I == 3 : Dig2  Decode_Digit(TerminalInput) • If Op == ‘e’ E  0 • Tmp TerminalInput, I = I+1 • (I == 3) && Tmp == 20h (space): • Reg[Dest]  Op(Reg[Dest],Dig1) • I = 0 (I==4): • Reg[Dest]  Op(Dig1,Dig2) • I = 0 Put resultin the reg Written in dest

  5. Register sizes: • Op – 2 bit • Dest – 2 bit • Dig1 – 8 bits • Dig2 – 8 bits • a to d – 8 bits • Tmp – 8 bits • E = 1

  6. Cond2 Cond1

  7. Control of the circuit • NextChar • Decode1Enable • Decode2Enable • Mux2 • Mux3 • Iwrite • Tmpwrite

  8. The control of the circuit Input Output

  9. Op_Decode

  10. Dest_Decode
