Question

Using ARM assembly Language:

Problem Statement: For this project, assume that some other procedure has read 8 temperature values from an A/D converter to a half-word array named Temp BCD in memory. The temperature values arc in BCD form. For example, a temperature of 125 degrees Fahrenheit would be stored as 0000 0001 0010 0101. Temperature values range from 0 -125 degrees Fahrenheit. Your task is to write a mainline that: Initializes registers as needed. Calls and passes parameters as needed to a procedure that converts the 8 BCD values to their binary equivalents and puts the results in order in an array called Temp BIN After return from the procedure, the mainline calculates the rounded average of the 8 binary temperature values and writes the average value to memory location named Temp Av.
