How does the beginbursttransfer signal work in the Avalon switch fabric?

Environment

BUILT IN - ARTICLE INTRO SECOND COMPONENT
Description

The beginbursttransfer signal is generated by the Avalon switch fabric for the first clock cycle of a burst when the burstcount signal is first asserted from a master port.  The beginbursttransfer signal will de-assert after the first clock cycle.  If the target slave generates a waitrequest when the address and burstcount are asserted, the waitrequest has no affect on the beginbursttransfer signal (The beginbursttransfer signal will not be held after the first clock cycle if waitrequest is asserted by the slave port).  The burst slave peripheral must be aware that the beginbursttransfer signal will only be present at the first clock cycle of a burst transfer and not when the address and burstcount are first captured by the slave port.

 

For additional information on the beginbursttransfer signal please refer to the Avalon Interface Specification (version 3.1, April 2005).
