Answer 1

Answer #1

a. CALL and RET both are 3 bytes instructions where first byte is for OP code and other two bytes are the address of the subroutine you are calling and returning to respectively.
b. With each CALL instruction, the stack pointer pushes one entry , hence incremented by 1.
c. With each RET, the control is transfered to the poped elemnent by the stack, hence with each RET , the stack pointer is decremented by 1.

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?...
