Hi,

The AMBA5 spec for ACE5 shows some new signals versus ACE4 :

VAWQOSACCEPT

VARQOSACCEPT

AWAKEUP

ACWAKEUP

SYSCOREQ

SYSCOACK

How are these used in an SOC system ?

For example, I think but I'm not usre if VAWQOSACCEPT, VARQOSACCEPT is output by each slave…

Hi,

1) ARBAR/AWBAR

These two signals are mentioned : ARBAR, AWBAR but in the AMBA5 spec F2.1 Signal Matrix, these signals are listed as "N" (must not be present), page 419 and 420 of 440 pages. 

So are these signals used on the ACE5 interface…
