Serial vs. ParallelParallel Communication• Parallel ATA ( PATA )
– Former Standard data storage connection
•Hard disks, Solid State Drives, CD ROM– Max. cable length of 18 inches
•Clock Skewing

Serial vs. ParallelParallel Communication• Front Side Bus ( FSB ) …
– Link between CPU and Memory controller– Low cost –Allows multi-core processing

Serial vs. ParallelParallel Communication• Front Side Bus ( FSB )
–Max throughput • Width (Bytes) * CLK Freq * Transfers per CLK Cycle
32 bits ( 4 Bytes) * 200MHz * 2 xfers per cycle = 1600 MB/s– Fading Technology
Transfer rate [MB/s]
Frequency [MHz]

Serial vs. ParallelParallel 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

Serial vs. ParallelParallel 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

Serial vs. ParallelParallel 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.
