The following code demonstrates a simple look-up data table to quickly convert Celsius to Fahrenheit.

(Assembly)

Re-write the table program to sort 20 random values stored in the internal FLASH. Use the sorting method of your choice; sort from max to min or min to max. Store the sorted numbers to SRAM as the output.
