Answer for d only

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. (10%) b. By using the same method as shown in Lab 2 write Verilog code to perform the modified arbiter. (40%) c. Output from the arbiter will be used by HPS. Suggest one application by using the output from the arbiter. (10%) d. Write C code to read the output from the arbiter. (40%)
