I want all the answer for this question Question $2$:

The arbiter FSM defined in Figure $1$ may cause device $3$ never get serviced if device $1$

and $2$ continuously keep raising requests, so that in the Idle state it always happens

that device $1$ or device $2$ has an outstanding request.

a$.$ Modify the proposed FSM to ensure that device $3$ will get serviced such that if

it raises a request, the device $1$ and $2$ will be serviced only once before the

device $3$ is granted its request.

b$.$ Write Verilog code to perform the modified arbiter.

c$.$ By using the modified arbiter, design the following application and implement

on the Zynq Board:

a$.$ Data are stored at three different files in SD card $($File $1,$ File $2$ and File

b$.$ When device $1$ is triggered, File $1$ will be read from the SD card and data

will be displayed on LEDs or PC$.$

c$.$ When device $2$ is triggered, File $2$ will be read from the SD card and

data will be displayed on LEDs or PC$.$

d$.$ When device $3$ is triggered, File $3$ will be read from the SD card and data

will be displayed on LEDs or PC$.$

Note: Input pin does the triggering process

d$.$ Modify the application in $($c$)$ by using automated triggering process.

Implement the modified system on the Zynq Board.
