AXI Locked Write and Lock Scope

Deepak Ameta

Hi All,

       1)  1st master is doing locked write transfer to 'X location after that, Can 2nd master initiate a read normal transfer for 'Y address in same slave? . And still unlocked transfer is not initiated by the 1st master?.

       2)  Locked transfer is for Bus channel or specific Slave region?

 

Regards,

Deepak

    Hi Martin,

      Thank you, I have got more clear about LOCKED access. I have ohter questions about LOCKED transfer.

    • 1st master is initiate locked write transfer to 'X location after that, Can Same master initiate a read locked/normal transfer for 'Y (different) address in same slave before unlocked transfer is issued by same master?.
    • To complete the 'Exclusive operation, master should initiate Exclusive read followed by Exclusive write  transfer so, To complete Locked transfer is there any read followed by write sequence must be initiate?   

    Regards,
