How program and data memory fetches can be overlapped in a Harvard architecture?

In Harvard architecture, the program memory space is distinct from data memory space. Such architecture requiring two connections. It can perform instruction fetch ( from program memory ) and data memory fetch simultaneously , by adopting a pipelined instruction execution approach, as shown below. A typical instruction execution consists of performing Fetch instruction, Decode instruction, Fetch operands, execution operation , store results. Then, by adopting a pipelined approach, which is possible in Harvard architecture, it is evident that the instruction throughput increases by overlapping. It is simple to imagine that in the above case, if all the above states are executed "one after the other" , the execution time of the instruction will be longer than when it is pipelined.

How many fetch cycles a three byte instruction requires for its execution?

There are three fetch cycles in a three byte instruction. The first one is four clock cycles long, while the other two are three clock cycles long. Depending on what the instruction does, there will then be more read/write cycles.
