  • AMBA AHB5 : Stable Between Clock Question

    Hi All,

    I have a question on AMBA5 AHB feature : Stable_between_Clock property

    The AMBA5 AHB Specification describes:

    Signals that are described as being stable are required to remain at the same value when sampled at different rising clock edges in an…

  • AMBA Adaptive Traffic Profiles

    The performance requirements of computing systems have been growing rapidly, year on year. Demand is further increased by the many new performance-demanding applications that are emerging across multiple market segments, such as machine learning (ML)…

  • Significance of [MS] and [LS] in big-endian data bus in AHB5 Specification

    Hi,

    As indicated in few previous answers (Link Given below) on the big-endian, I believe that the big-endian type in AHB-Lite Spec is BE32. And further the AHB5 Spec added another type of big-endian as BE8. Hence, the active byte lanes for a 32-bit big…

  • Please explain some of the new ACE5 signals in relation to the MASTER and INTERCONNECT behavior

    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…

  • Further explanation needed for VAxQOSACCEPT, AWAKEUP, ACWAKEUP and SYSO*

    Hi ARM/arktos,

    Seems like this online discussion is not working properly.

    I ask a question, you reply, and if I reply the discussion tool doesn't echo back my reply by email.

    So most likely you may not see it.

    Below is my reply to your answer to my…

  • AHB Lite Response

    Hi All,

                               I have doubt in ahb_lite hresp signaling when the address phase is extending.

    In the following diagram transfer address c is extending because of data phase of B.

    In 3rd clk cycle address C is sampled so that shall we expect the…
