A C program has been compiled into the Atmel AVR assembly
language. The following instruction, which is located at address
0x002A, is executed:
i.) What is the binary value contained in the instruction
register (IR) when the instruction is executed?
ii.) What is the hexadecimal value of the program counter (PC)
when the instruction is executed?
iii.) If register r1 = 0x40 and register r2 = 0x02 prior to
executing the instruction, what are the contents of r1 and r2...
What does the instruction jal do? It populates the PC with the address given by the input. It saves the current PC (plus 4 bytes) to the $ra register and the populates the PC with the address given by the input. It populates the PC counter with the word currently stored in the $ra register. It allocates the input number of bytes (provided as an immediate value) onto the stack. 1 points QUESTION 6 What is a function pointer?...

Assume the program counter (PC) is initially equal to n. Assume that the word length of the processor is 1. a) How many fetches are required to make PC equal to m if there are no branch instructions between n and m? b) What is the content of the instruction register (IR) when the PC’s value is n+k?

5 Exercises Now that everything is working you can try the following exercises. To complete them you will need to refer to the documentation in Appendix A- The MiteASM Assembler and Appendix B - The MiteFPGA Processor. Write an assembly language program for an over counter for a cricket umpire. This should display a count on the 7-segment display. The count should increase by 1 when button 0 is 1. pressed. It should reset to 0 when button 1 is...
