Question:  In a strobe-based destination-initiated data transfer which of the following signals is placed first?

A    Data signal

B   Acknowledgment signal

C     Clock signal

D   Request or Strobe signal

Answer:  Request or Strobe signal

 

Aspect           Description
Initiator Destination (receiver) initiates the process.
First Signal Request or Strobe signal is placed first to signal readiness.
Process Flow ·        Destination sends a Request/Strobe signal to the source.

·        Source, upon receiving the signal, places fresh data on the data bus.

·        Destination reads the data from the data bus.

·        The Strobe signal is turned OFF once data is read.

Purpose Coordination of data transfer initiated by the destination.
Efficiency Ensures data transfer only when the destination is ready, reducing data transfer errors.
Data Bus Utilization Data is placed on the data bus only when requested, minimizing bus traffic.
Applications ·        Interfacing in computer systems

·        Synchronous data transfers

Benefits ·        Minimizes data transmission errors

·        Efficient data transfer

·        Reduced bus traffic
