Question
![In this programming activity, you will be writing an
LC-3 assembly program that will examine a given 16-
bit value stored in a given memory location. Your
program should count the number of 1s that occur in
the given value.
HINT: You can examine each bit of a given value by
shifting the value by one bit to the left repeatedly and
looking at the resulting value of MSB (sign bit).
Your program should assume that the initial bit
pattern is in memory location labeled PATTERN. Your
program should count the number of 1s in PATTERN
and store the count in memory location labeled
NUM_ONES. Your program should start at memory
location x3100.
Example: If PATTERN contains the bit pattern 1111
0000 0000 1111 (XF0OF), then your program should
store 8 into NUM_ONES.
You will need to demonstrate the correct execution of
your program by using the LC-3 Simulator.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fac5a802f-a869-4dc8-8182-e6c6863d00b7%2Fdd2ed70d-28c3-4de9-a99e-f346f4abcbbf%2F4bsp2z9_processed.jpeg&w=3840&q=75)
