2. Write an 80x86 assembly language program that reads byte size signed integers from memory and counts the number of zeros. Store this count in memory. End when you get a negative number. (20pts) For example: nums DB 4, 0, 0, 12, 6, 8, 0, 4, -1 count DB 0 after executing the procedure count should be 3 count DB 3.

Write a program in assembly language that loads register R2 with the word in memory location which is 10 bytes above the address in R0; and loads register R3 with the word in memory location which is 10 bytes below the address in R1. Your program must compare the two numbers in R2 and R3. If number in R2 is less than or equal to the number in R3 it must add the two numbers and save the result in...

Problem 1 Write a find subroutine that can locate a specified 8-bit quantity in a null-terminated string 8-bit quantities. (Remember that null terminated means "it ends with zero"). The subroutine is passed two parameters. The pointer to the array is passed in array X, the value to be found is passed in ACCA. The function should return the index of the first occurrence of the value in ACCB, or -1 (0xFF) if the value is not found. a) Write the...

Write a function decompressed(count_tuples)
that takes a list of counts of '0's and '1's as defined above and
returns the expanded (un-compressed) string. You may assume that
the first value of count_tuples has a count that is
greater than or equal to zero and all other counts are greater than
zero.

Write an ARM assembly language subroutine (named nfibo) to calculate and return the n-th Fibonacci number. Fibonacci numbers (or a Fibonacci sequence) are a series of numbers with a property that the next number in the series is a sum of previous two numbers. Starting the series from 0, 1 as the first two numbers we have 0, 1, (0 + 1) = 1, (1 + 1) = 2, (1 + 2) = 3, (2 + 3) = 5, (3...
