Homework2

1. Represent the following signed numbers in 32-bit two’s complement: (1).

+12, (2). -12.

2. Download Mars , the MIPS simulator, and write a MIPS program that

will print the string Hello on the terminal. Make sure you run the program

on the simulator and it actually works.

3. Every register stores 32-bits. Suppose now that the register s1 stores the

following 32 bits:

111 · · · 1111

where each bit is simply 1.

(1). When I run the instruction add s2, s1, s3, what’s the value of the

number stored in s1 ?

(2). When I run the instruction addu s2,s1,s3 instead, what’s the value

of the number stored in s1 ?
