Build an assembly language subroutine named SuperfyRO that will find the largest of the values in the registers RO, R1, R2, and R3 and copy that value into RO. For example, if RO contains 28, R1 contains 15, R2 contains 3, and R4 contains 77 when your subroutine is called, when your subroutine is finished RO will contain 77, R1 will contain 15, R2 will contain 3, and R4 will contain 77. Your subroutine must be placed at address Ox30 in program memory and must use only instructions that are contained in the CS150 AVR instruction subset. Your subroutine cannot use any data memory locations or any registers other than RO, R1, R2, and R3 to solve this problem.

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: 52937 then when the function returns, the array will have been changed so that it looks like this: 5 7 16 19 26
in assembly language x86 Masm, Write a program that calculate the first seven values of the Fibonacci number sequence, described by the following formula: Fib(0) = 0, Fib(1) = 1, Fib(2) = Fib(0)+ Fib(1), Fib(n) = Fib(n-1) + Fib(n-2). Implement the Fibonacci number sequence using a recursive function call. Take screenshots showing the stack frames on the memory window and the results.
Write a program that USE X86 ASSEMBLER LANGUAGE AND RUN IT WITH DEBUG CONSOLE that performs the sum of the squares of a series of numbers entered by the keyboard. To do this, the program will first ask for the amount of numbers to read. It will then read those numbers, execute the corresponding sum and finally print the Outcome.
For this assignment, you are to write a MIPS assembly language program using the MARS IDE and assume a system has 31-bit virtual memory address (so no worry about negative numbers) with a 4-KB page size (4096 bytes). Write a MIPS program that accepts an integer input that represents a virtual address and outputs the page number and offset for the given address in decimal. The output should look like: The address 19986 is in: Page number = 4 Offset = 3602 Check to make certain your program works. You can use the output from 19986 given above as a test, but I will use other numbers to test it. Submit the MIPS assembly language code and a screenshot showing a test run.
Write an assembly (8085) code to check if a number is even or odd. The number will be stored in a memory location 0211. The number can be anything. So your code has to be dynamic that works for any number. If the number is even then store 1 in memory location 0222, otherwise store 0 in 0222.
Write a code in sim8085 for the following problem: The pressure of two boilers is monitored and controlled by a microcomputer works based on microprocessor programming. A set of 6 readings of first boiler, recorded by six pressure sensors, which are stored in the memory location starting from 2050H. A corresponding set of 6 reading from the second boiler is stored at the memory location starting from 2060H. Each reading from the first set is expected to be higher than the corresponding position in the second set of readings. Write an 8085 sequence to check whether the first set of reading is higher than the second one or not. If all the readings of first set is higher than the second set, store 00 in the ‘D’ register. If any one of the readings is lower than the corresponding reading of second set, stop the process and store FF in the register ‘D’. Data (H): First set: 78, 89, 6A, 80, 90, 85 Second Set:71, 78, 65, 89, 56, 75
Write a 6502 assembly language program which implements the following pseudocode: i = 0 for num = x to y counting by 5 ar[i] = num i = i+ 1 For your implementation, x and y are stored in the first and second bytes of the zero page, ar starts at the third byte of the zero page and continues for as many bytes as necessary. The outcomes of an example run are below: x=0, y=15, ar={0, 5, 10, 15}
There is an application that requires the following hardware: an Intel 8031, a Program ROM of 8Kx8, a Data ROM of 4Kx8 for look-up tables and a Data RAMs of 8Kx8. The memory map of the design: Program ROM should start at address 0000H. Then, the Data ROM should come above the Program ROM. Finally the Data RAM must go to the top of the memory map. There should be no gaps between the memory addresses of the external ROMs. Calculate the address space of the ROMs and RAMs of your design.
Write an LC-3 assembly language program that counts the number of 1s in the value stored in R0 and stores the result in R1. For example, if R0 contains 0001001101110000 (x1370), then after the program executes, the value stored in R1 would be 0000000000000110 (decimal 6) Here are some hints ORIG x3000 AND R5, R5, #0 ADD R5, R5, #1 ;R5 will act as a mask AND R1, R1, #0 ;zero out the result register AND R2, R2, #0 ;R2 will act as a counter LD R3, NegSixt MskLoop AND R4, R0, R5 ;mask off the bit Add code here... if you want more than a 0 Solicit the number to be inspected via the keyboard. 10 points for a single digit (e.g. 5) decimal number, which must be converted to binary. 20 points for a two digit (e.g. 55) decimal number, which must be converted to binary.
