Write a vhdl using 2 processes and one hot encoding to design a simple computer bus can only do bus reading. when the input read_bus is low the bus is in the state idle but when it is high the bus reads three words a, b, c in this order, each one takes one clock cycle to be performed. during the reading if read_bus drops to 0 the system does not interrupt the reading (does not come back to the idle state). after reading c, if read_bus is 0 then the system goes to state idle, but if the read_bus is equal to 1 the bus performs the reading again in the same order (a, b, then c) without coming back to the state idle.

Usually, when we sniff packets, we are only interested certain types of packets. we can do that by setting filters in sniffing. scapy’s filter use the bpf (berkeley packet filter) syntax; you can find the bpf manual from the internet. set the following filters and demonstrate your sniffer program again (each filter should be set separately): (a) capture only the icmp packet. (b) capture any tcp packet that comes from a particular ip and with a destination port number 23. (c) capture packets comes from or to go to a particular subnet. you can pick any subnet, such as 128.230.0.0/16; you should not pick the subnet that your vm is attached to.
