In lab this week you wrote code that simulates a simple computer; that code could be turned into a circuit. Assume that we have set up the following: • an 8-bit pc register, with 8-bit input pc_in and 8-bit output pc_out. • memory returns the instruction on the 8-bit output code_byte. Your code used a get_bits function we provided to retrieve a 2-bit part of the instruction (code_byte) as the index into the register file for register A. In a physical chip, the simplest correct form of the 2-bit extraction would be to: needed (no gates) O A. Connect 2 of the 8 wires that make up the code_byte to the register file a OB. A right-shift circuit to move the 2 bits for A to the least significant bits and use those two wires OC. A mux with 8 bits of the code_byte as inputs and the 2 bits we want as the selector OD. An even larger circuit than the ones above

For your discussion question response, please provide a response to each of the following questions. Make sure that you include the question followed by your answer to the question in your posting. In the description of the Hack machine language in chapter 4, it is stated that in well-written programs a C-instruction that may cause a jump should not contain a reference to M, and vice versa. Discuss why this should be avoided. Research the concept of interrupts in a computer. You may want to look into how the Z80 microprocessor handles interrupt. A good source of Z80 information is Zaks, R. (1980). Programming the Z80. Sybex. Download the pdf. FYI, The Z80 8 bit microprocessor has been in production for forty years. Knowledge of the Z80 is a great lead-in for further study in more complicated machines.
Write an assembly program that reads from PORTA. If bit 5 of PORTA is high then it writes 4× PORTA in PORTB; otherwise, it writes PORTA+3 in PORTB. You cannot use multiply instruction in your program.

Our ‘mostly 8-bit’ design has the problem that computed pointers can only range over256 bytes of memory. This makes using the screen difficult (though not impossible!). Howmight you extend the instruction set to make this easier? [Hint: think about spare bits inthe C-instruction.]
Task Write a program in the ARMLite assembly language which generates the Fibonacci number F(12) and stores the value in register R6. • You must use a loop to generate the value. Partial marks will be given for otherwise correct but non-loop based solutions • There is no limit on the number of registers you can use • The stack memory may be used, but is not required • Other memory access is not allowed or needed • Add a comment to the top of your program describing it's behaviour. You should make use of comments to describe your code's sections. Submit your program as a plain text file. If you are using the ARMLite simulator, it can be exported directly using the 'Save' button.
Write a assembly code for 8086/8088 that replace the contents of each cell with the sum of the contents of all the cells in the original array from the left end to the cell in question. Thus, for example, if the array passed to the function looks like this: 5 2 9 3 7 then when the function returns, the array will have been changed so that it looks like this: 5 7 16 19 26
