Parallel Communication• Laboratory Instrumentation Bus IEEE-488
•Short-Range •Been in use for over 30 years: Designed late 1960s •Commonly known as HP-IB •Daisy Chain Connections •Employs 16 signal lines:
–8 bi-directional used for data transfer–3 for handshake–5 for bus management

Parallel Communication• Three Criteria when Choosing
Parallel1. Speed – Bit Rate and Skew2. Cable Length – Crosstalk3. Complexity – Simple
− Requires only a latch to copy data to the data bus

Parallel Communication• Use of Parallel Communication in RF
Communication– In place of Morse Code (one bit at
a time)– Multi-input Multi-output– Groups of Bits Called “Symbols”– Recent Techniques such as DVB-T
have transmitted over 6048 bits in parallel.

Benefits•Ideal over long distances
–Much cheaper than Parallel
•Can Operate at a faster frequency than parallel•Synchronization Difficulties Reduced
–Less wires to worry about

Synchronous •Regulated by an external clock
–Requires an extra wire for clock signal
Asynchronous •Regulated by special signals along transmission lines

Synchronous Synchronous
•Utilizes two different signals on separate lines
–First signal is clock signal that is shared between the two devices–Second signal carries the data

Asynchronous Asynchronous
•Signals are specified by predetermined data transfer protocols.•Preset frequency between devices
–Signaling sequence specifying beginning and ending of signal
•Frequency set at beginning of transfer
–Signaling sequence specifies beginning and ending of signal as well as transfer rate
