Scenario: You are to design synchronous and asynchronous circuits that will allow the following requirements to be met. Tasks: 1. Packet number checking A synchronous sequential machine is to have a single input line and a single output line. The circuit is to receive messages of 4-bit words coded in binary (least significant bit first). The purpose of the circuit is to detect whether the number coming in is a prime number (divisible by only itself and 1). Thus, the output is to become 1 whenever a 4-bit word does represent a valid prime number. At the end of each word the machine is to return to the reset starting state. Steps: 1) Draw a State Diagram (Mealy) and check for redundancies 2) Then assign binary State Identifiers. 3) Make a Next State Truth Table (NSTT) 4) Select a bistable type 5) Determine expressions for the bistable inputs 6) Determine expressions for the outputs 2. Monitoring System A monitoring system sends 1s positive going pulses to a device to ensure that it is operating correctly. The device will respond by lowering its normally high line as soon as it receives the pulse then raising the line again within the 1s if working correctly. If the device line doesn’t respond correctly or respond at all then an alarm must occur. 1) Carry out a design for the asynchronous system that will realise the requirements up to the point where internal conditions are designated to the lines in the merged table. 2) Explain what the designer would have to do to ensure the system was hazard free and the output was as short as possible.

A crush of popular social-media toys – Facebook, Twitter, Google, Yahoo, Yelp, social games, Skype, YouTube and Quora, to name a few – has opened the lines of communication between millions of people as never before. But the glut of tools and their features – chat, messages, instant messages, texting and tweets – has led to multiple conversations that can be head-spinning. People are drowning in a deluge of data. Corporate users received about 110 messages a day in 2010, says market researcher Radicati Group. There are 110 million tweets a day, Twitter says. Researcher Basex has pegged business productivity losses due to the “cost of unnecessary interruptions” at \$650 billion in 2007. What can you do to manage social media? Is there a way to use social media in a positive way in the workplace?
