From Rome to Arabic Solution

Write a correct program in MIPS - QtSpim assembly language that:

 

Reads input Roman Numerals as ASCII text characters.
 

Calculates the equivalent decimal value.
 

Writes the calculated value as Arabic Numerals (integer) to the QtSpim                display screen with the appropriate commentary text.
 

The program must correctly calculate the values of these seven
Roman Numeral digits:

 

                                           I            V         X         L          C         D         M
 

5)  Calculate the value, and display the result of these Roman Numerals:

 

MCDXCII
CDIX
MCMXLVIII
 

 

You need to let the user know whether the input must be UPPER case or lower case.

 

You do not need to check for  ‘valid’ Roman numbers, but you do need to calculate a consistent decimal value.  For example, while VIIII is not considered ‘valid’, you should none the less calculate the value as 9.  Commonly, IV = 4;  IX = 9; XL=40; CM=900

 

Use the System Service calls on page A-44 of the textbook for the input and output.

 

Your program should display a message when it stops.

 

A loop to allow testing would be helpful.
