Implement half precision floating point addition in MIPS assembly language. Prom

Question

Implement half precision floating point addition in MIPS assembly language. Prompt user to

input two floating point (decimal) numbers and compute and display the sum. Use algorithm

depicted in figure 3.15, pg 252 in the textbook.

In half precision format, 16 bits are used to represent a floating point number. The exponent field

is 5 bits wide while the significand field has 10 bits.

You will need to convert single precision floating point number to half-precision floating point

number and then perform your calculations.

Your program should be able to handle negative numbers as well. Also, if user enters an out of

range number for half precision format, your program must raise an exception message.

You MUST NOT use the MIPS floating point instructions.

As always, after one set of inputs, program must ask if the user wants to enter more numbers.

Explanation / Answer

For Example:

Enter a floating-point value: 1

Enter a floating-point value: 1

Sum: 2.000000000000000000

Enter a floating-point value: 2.2

Enter a floating-point value: 1.4

Sum: 3.599999904632568400

Enter a floating-point value: -1.34

Enter a floating-point value: 3.4

Sum: 2.059999942779541000

Enter a floating-point value: 10.5

Enter a floating-point value: 100.2

Sum: 110.69999694824219000
