1. At the combinational element level in Logisim or Multisim , define an 8-bit CPU with the following features:
   1. ALU with ADD and AND and XOR.
   2. Register-based ALU operations (aka R-type instructions).
   3. Data memory.
   4. Program memory.
   5. STORE operation.
   6. LOAD operation.
   7. Register bank.
   8. Program counter.
2. Demonstrate the execution of the following assembly program:
   1. LOAD R1, 0x0000
   2. LOAD R2, 0x0004
   3. ADD R3, R1, R2
   4. STORE R3, 0x0008
3. Write short assembly programs to demo the other two functions
