MIPS(Microprocessor without Interlocked Pipelining Stages)

Question 1

Reg file in MIPS architecture is….

Answer 1

small and fast

Question 2

load and store functions are used to access data in the memory

Answer 2

it is slower and takes more energy than the register file (which is like cache and holds the current data that is being used by the current instruction in the current instruction register)

Question 3

3 types of instructions in MIPS

Answer 3

Data Operations: add, sub, like ALU stuff
Data Transfer: load, store
Sequencing: conditional and unconditional branching instructions

Question 4

lw R1, 126(R2)

Answer 4

Load word instruction, loads the word from the memory location ‘126+value in R2’ to R1(Destination Register)

Question 5

MIPS has

Answer 5

32 General Purpose Registers, R0-R31

Question 6

registers in MIPS are…

Answer 6

32 bits wide

Question 7

R0

Answer 7

is always zero/ is hardwired to zero

Question 8

Registers R29 and R3…

Answer 8

are used for function calls

Question 9

Program counters

Answer 9

is a special register that keeps track of the current instruction

Question 10

add r1,r2,r3 is the same as add r1,r3,r2

Answer 10

TRUE

Question 11

R5=(R5+R6)+R7 needs at least 1 temporary register to be executed

Answer 11

FALSE,
No temporary registers needed since:
R5=R5+R6
and then
R5=R5+R7 (because value of R5 is now (R5+R6))
