Question

Translate the following C statements into MIPS assembly language. Assume that all variables are 32-bit signed integers. Translate the statements exactly as written; do not use any algebraic rules to simplify the expressions, and do not rearrange the order of operations unless MIPS requires you to do so. Use t registers for temporary values as needed.

a=b⋅c
b=(a⋅b)−(a−b)

Answer 1

To translate the given C statements into MIPS assembly language, we need to consider the order of operations and use temporary registers (t registers) when necessary.

Step-by-step explanation:

To translate the given C statements into MIPS assembly language, we need to consider the order of operations and use temporary registers (t registers) when necessary.

1. To translate the first statement, which is 'a = b * c,' we can use the MIPS instruction 'mul' to multiply the values of registers b and c. Then, we store the result in register a.

2. To translate the second statement, which is 'b = (a * b) - (a - b),' we need to break it down into smaller steps. First, we perform the multiplication of a and b using the 'mul' instruction and store the result in a temporary register. Then, we subtract the values of registers a and b using the 'sub' instruction and store the result in another temporary register. Finally, we subtract the value in the second temporary register from the value in the first temporary register. The result is then stored in register b.
