Task

$1$

trace the flow of bits for each labeled line in the single cycle CPU

diagram. You may assume a minimum number of lines to carry the information. The instruction to trace

is: addi x

$5$

$,$

$$x

$1$

$0$

$,$

$1$

$2$

$.$

$$Assume register x

$1$

$0$

$$contains the value

$8$

$.$

$$For numbered lines, you only need to

fill in those relevant to the instruction. You should fill in all control lines.

$2$

Same idea as task

$1$

$,$

$$except you will trace the bits of the instruction: sw x

$9$

$,$

$1$

$2$

$($

sp

$)$

$.$

$$You should assume

that x

$9$

$$contains the value

$1$

$4$

$.$

$$The stack pointer

$($

sp

$)$

$$contains the address

$1$

$6$

$.$ Fill in the chart with the corresponding bits after each instruction. Only fill in necessary bits, there isnt enough space
