1. At the combinational element level in your simulator of choice, 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, Ox0000 2. LOAD R2, 0x0004 3. ADD R3, R1, R2 4. STORE R3, Ox0008 3. Write short assembly programs to demo the other two functions
