Which one will take more time front door access or back door access and why?
In reply to hurmath@fldec:
The frontdoor access executes in any way a bus cycle. The backdoor access does not, resulting in saving time.
In frontdoor access you follow the proper protocol (applying address/ writing data etc) and flows through proper channel.so it consumes significant time.
Whereas in backdoor access there will be direct access of register instance bypassing the actual protocol which makes it faster saving several cycles.
