QUESTION 5 What result will be in AVR registers r16, r18 and the status register (Z, C, N, V bits) after the execution of all of the following AVR assembly language instructions: Idi r16, 77 Idi r17, OxAB ldi r18, 34 and r16, r17 add r18, r17 Your answers should consist of binary digits only (0's and 1's)- your r16 and r18 values should show 8 binary digits; your status register values should be shown with a single bit. r16:...
Suppose that an 8-bit microcontroller has a 16-bit stack pointer and uses a 16-bit register to access the stack from the top. Assume that initially the stack pointer and the 16-bit register contain 20C016 and 020516 respectively. After the PUSH operation 1. What are the contents of the stack pointer? 2. What are the contents of memory locations 20BE16 and 20BF16?

Suppose you have two 8-bit registers, A and B. containing signed two's complement values A contains the value 11001110 B contains the value 11111010 What is the decimal value of the difference between them (A - B)?
Assembly questions 1. Each of the 8 32-bit general purpose registers in the 80x86 family contains 8 16 bit registers, and 8 8 bit registers. True or false? 2. When we need to see if a math operation resulted in a zero answer, we may use: a. ESP b. keyboard latch c. memory address bus d. EFLAGS 3. The operation: add (radius, eax) ; a. changes the contents of radius. b. changes the contents...
For three sequences X[n],y[n],z[n], assume that Y(w)= X(-w) and (w)= X(w + TT) in the Fourier domain. In the z-domain, what are Y(z) and Z(z), respectively? A. X(-2) and - X(z) B. X(- z) and X(2-1) c. -X(z) and X(2-1) D. -X(z) and X(-2) E. X(z-) and X(-2) F. X(z-1) and - X(z) G. None of the above.
You are given a homework processor (HPro) capable of addressing 32 8-bit (1 byte) wide registers. However, it has only 29 physical registers. Register RO, R1 and R31 are not physically implemented. Instead, every read from RO, R1 and R31 will return a constant zero (00000000), constant one (00000001) and all ones (11111111), respectively. Every write to RO, R1 and R31 will go to null (dummy write). Assume that all other registers have initially unknown (X) state (This in fact...
Assembly language (MIPS) Let register $8 be x and register $9 be y. Write a program to evaluate: Z = 3x - 5y+5 Leave the result in register $10. Inspect the register after running the program to check that the program works. Run the program several times, initialize x and y to different values for each run.
