 Write some verilog for a 3 to 1 arbiter, with a priority client and 2 clients in a round robin.1 AnswerPseudo code: if (priority request) grant priority client else if (client1 and not client 2) grant client1 else if (client2 and not client1) grant client2 else if (client1 and client2 and client1_last) grant client2 else if (client1 and client2 and client2_last) grant client1 end note: 2 to 1 round robin algorithm involves remembering which client was granted last and giving them lower priority. He wanted synthesizable code, so make sure to brush up if you haven't been doing that for a while.
