where N = number of machine language instructions executed, S = average number of basic steps needed to execute one machine instruction, and R = clock rate in cycles per second.
What changes to N, S, and R will decrease T?
2. Assume that an automobile assembly process takes 4 hours. 
If the stages take the following amounts of time, then what is the time between completions of automobiles?
Chassis 45 minutes
Motor 1 hour
Interior 1 hour and 15 minutes
Exterior 1 hour
3. Consider the simple RISC Assembly Language:
| Type of Instruction | Assembly Language | Register Transfer Language Description |
| Memory Access | Load R1, Mem |  |
| Store R1, Mem | Mem [Mem] | |
| Move | Move R1, R2 | R1 R2 |
| Move R1, #100 | R1 100 | |
| Arithmetic Instruction (reg. operands only) |
Add R1, R2, R3 | R1 R2 + R3 |
| Sub R1, R2, R3 | R1 R2 - R3 | |
| Conditional Branch |
Compare R1, R2 | Sets condition codes |
| BGT LABEL | Branch to LABEL if conditions codes are set for < | |
| Unconditional Branch |
B LABEL | Always Branch to LABEL |
