I am having an issue developing a program that calculates a polynomial function. I know how to do an MUL(Multiple) and IDIV (Division) but fail to develop the instruction to create a program to calculate a polynomial function exercise. We required writing certain coding format to be complete this exercise for assembly code. I need a help to solve this problem and tomorrow night?

Goal: To become familiar with allocating memory for your program, gain experience in dealing with 8-bit numbers including signed numbers and 16-bit numbers, and understand and use some basic instructions such as arithmetic instructions.

Instruction:

1. Write an assembly program to calculate the value of following polynomial function.

2. Use MUL and IDIV instructions.

3. Use DS.B and DS.W to create variables with the right sizes to store and retrieve data.

4. Have an EQU section, a data section, and a code section.

5.use following formula to raise a number to the desirable power: x2 = x*x, x3 = x2*x and x5 = x2*x3. Please save every calculation result to memory. Please pay great attention to the issue of data size: Should a piece of data be stored in one byte or two bytes?

This example coding format that is required of us to create this exercise:
