problem: There are various 8-bit microcontrollers in the market. In this report, search the web and find out four microcontrollers. (Cautiously cite your references)
A) For each microcontroller, describe a meaningful block diagram and a short explanation of its architecture.
B) Summarize the key architectural characteristics of these microcontrollers which you, as a designer, view significant.
C) Assume that you are in charge of recommending one of these four microcontrollers for packet processing applications. Informally speaking, such are applications in which a big stream of data packets with a uniform format (that is, header fields, payload and trailer fields) are received, manipulated and resent. Validate your choice of proposal.
