Use the following information for all parts of the question: Memory Access = 640 ps ALU Operations = 320 ps Register Access = 160 ps 1. If we implement the DataPath as a single-cycle using variable cycle length, fill in the cycle time for the following statement types (critical data path) in ps. R-Type: = [A] ps Load Type = {[B] ps Store Type = [C] ps Branch Type = [D] ps Jump = [E] ps 2. If we implement the above DataPath using a single-cycle with fixed length, the cycle length would be [F] ps.

Question

Help me with these computer architecture questions, please.

I need help with questions 1 and 2.

**Title: Understanding Data Path Implementation and Cycle Calculation**

**Instructions:**

Use the following information for all parts of the question: 

- **Memory Access** = 640 ps
- **ALU Operations** = 320 ps
- **Register Access** = 160 ps

---

**1. Variable Cycle Length in Single-Cycle Data Path Implementation**

To implement the Data Path as a single-cycle using a variable cycle length, fill in the cycle time for the following statement types (critical data path) in picoseconds (ps).

- **R-Type:** = \([A]\) ps
- **Load Type:** = \([B]\) ps
- **Store Type:** = \([C]\) ps
- **Branch Type:** = \([D]\) ps
- **Jump:** = \([E]\) ps

---

**2. Fixed Cycle Length in Single-Cycle Data Path**

If we implement the above Data Path using a single-cycle with a fixed length, the cycle length would be \([F]\) ps.

---

**3. Average Time Calculation with Instruction Mix**

Given a program running with the following instruction mix:

- **R-type** = 50%
- **Load type** = 20%
- **Store type** = 15%
- **Branch type** = 13%
- **Jump** = 2%

To find: The average time to execute an instruction is \([G]\) ps.

---

**4. Multi-Cycle Data Path Implementation**

If we implement the Critical Data Path using multiple cycles for each instruction (where each stage = 1 cycle), fill in the number of cycles required for each instruction type:

- **R-type:** = \([H]\) 
- **Load-type:** = \([I]\) 
- **Store type:** = \([J]\) 
- **Branch type:** = \([K]\) 
- **Jump:** = \([L]\)

---

This exercise helps in understanding the effective cycle time calculations and instruction handling in different data path implementations in computer architecture.
