Hi
guys!

I want to know when a ahbmaster control the ahbbus,if it sends a IDLE or BUSY transfer,what arbiter will do.Will arbiter terminate the control of the ahbmater.
Amba supports early termination,when does this happen?
Thanks!

Hi zhangpengyu:

1. When HTRANS is IDLE/BUSY, current grated master will keeping

have the ownership of bus. No new arbiter will happen.

2. The slave can determine when a burst has terminated early by

monitorning the HTRANS signals. If a NONSEQUENTIAL or IDLE transfer

occurs then this indicates that a new burst has started and therefore the

previous one must have been terminated.
