Computer Architecture Quiz 3

How many registers does MIPS machine has ?

The length of the registers in MIPS machine

Memory location in MIPS machine starts from 0 and each register takes 4 bytes

Instruction Length in Mips machine is :

Word Length in Mips machine is :

Register names in MIPS machine starts with :

Constant register that stores zero value, it is used in comparison operations

Return value registers. They are used to return result from the called functions

Argument registers. They are used to pass values to callee functions

Temporary registers. They are used for intermediate operations

Saved registers. They are used to store permanent data.

Return address register. It stores address of next instruction(in caller) to return the execution from callee to caller.

A signle line comment in Mips using :

c. X= 4 ; Y= X-20; X- >$s0 , Y-> $s1

Convert the next high level code to MIPS a. X=Y+Z ; X-> $s0, Y-> $s1, Z->$t0

Transfers data from Main memory to CPU.

Transfers data from CPU to Main memory.

It fetches 4 bytes from main memory to CPU

It fetches 2 bytes from main memory to CPU

It fetches 1 bytes from main memory to CPU

It stores 4 bytes from CPU in main memory

It stores 2 bytes from CPU in main memory

It stores 1 bytes from CPU in main memory

It stores 8 bytes from CPU in main memory

The Jump Instruction is :

To transfer the calling from callee to caller we will use Jr instruction

Index of half word array must multiply by 4 when converting it to MIPS

Load instruction moves data from CPU to main memory

To transfer the calling from caller to callee we will use JAL instruction

To transfer the calling from callee to caller we will use Jump instruction

No need to keep the values of ………………………….. In function calling

The address of caller next instruction is stored in $sp

In the branch Equal function " beq $reg1,$reg2, Label" .. If reg1 equals reg 2 we will go to next Instruction

In the branch Equal function " beq $reg1,$reg2, Label" .. If reg1 equals reg 2 we will go to label

In the branch Not Equal function " beq $reg1,$reg2, Label" .. If reg1 equals reg 2 we will go to label

In the branch Not Equal function " beq $reg1,$reg2, Label" .. If reg1 doesn't equal reg 2 we will go to label

In The Set Less Than function "slt $reg1, $reg2, $reg3" .. If reg2 < reg3 we will set reg1 to 1

In The Set Less Than function "slt $reg1, $reg2, $reg3" .. If reg2 < reg3 we will set reg1 to 0

To add a new value to system stack, we will decrease the value of $sp

To remove a value from system stack , we will increase the value of $sp

$sp points to maximum value in system stack
