Delay Loop:

Write a subroutine in assembly language that will delay for $0\mathrm{.}25$ seconds.

First you will need to calculate how many instructions you will need to execute

to fill $0\mathrm{.}25$ second. Use the posted DE$1-$SoC User Manual on Canvas to find the

clock speed of the ARM Cortex$-$A$9$ processor. Note, this architecture uses a $3-$

stage pipeline, that allows for roughly one clock cycle before moving onto the

next instruction.

After you have this number, you will need to create a For loop, which will

contain a counter to simply count down to a specified number. That number will

be calculated by taking the number of instructions you need $($which you just

calculated$)$ divided by the number of instructions in your For loop.

You will turn in a single $.$s file which contains a properly formatted function in

GNU assembly, that will loop so as to create a $0\mathrm{.}25$ second delay. You must

include your calculations as comments in your $.$s file.
