Programming questions
The assembly programming questions on this exam will be fairly simple.
None will be more than a single while
or if—else with a one or two statement body.
Make sure all your program examples
exit at the end of the implemented statement.
A few more things to get straight
- In C, any non-zero integer is
considered to be
trueand zero is considered to befalse. - The relational and logical operators return either 0 or 1.
- It doesn’t take many bits to address a memory location.
- If
Vis an array of integers; to accessV[i]in MIP32 assembler, you need to do a multiplication by 4. - Shift left two places to multiply by 4.
- The unary
&and*operators of C are used with pointers. - You can subtract pointers in C if they point to elements of the same array.
- If the MIPS32 instruction starts with 000000, it’s a an R instruction.
- In MIPS32, arguments are passed in
$a0to$a3and values are returned in$v0to$v1. - Check your answers.
- Explain your reasoning.
