16 Questions
What is the main difference between parallel and serial communication?
Parallel communication uses multiple wires running parallel to each other, while serial communication uses a single wire to transfer data one bit at a time.
What effect can clock skew have on parallel data transfer speed?
Clock skew reduces the speed of every link to the slowest of all of the links in parallel data transfer.
What can lead to inter-symbol interference and noise in parallel communication?
Crosstalk between the parallel lines in parallel communication.
What factor makes it difficult to balance many lines in parallel communication?
Equal propagation times for each line.
What is a characteristic of serial communication?
Transfers data one bit at a time using a single wire.
How do distributed reactance differences impact data transmission?
They result in different travel times across the whole line in parallel communication.
What limits the length of a parallel data connection?
Timing variation
Why are parallel buses hard to run at high frequencies?
They are difficult to route across a board without timing variation
Which company defines the ARM bus standard known as AMBA?
ARM
Which bus provides high clocking frequency and large throughput in the AMBA standard?
AHB
What role does the bridge play in the AMBA architecture?
Slave to the AHB bus
What type of bus is AHB in the AMBA standard?
Fast, parallel, multi-master, pipelined
What is the purpose of a burst transaction in parallel buses?
To reduce the amount of sequential addresses sent through the bus
How do pipelined buses differ from non-pipelined buses?
They can perform multiple transaction phases simultaneously
What is the main reason that makes it hard to run parallel buses at high frequencies?
Timing variation between signals
What limits the maximum frequency of parallel buses?
Variation in signal timing
