Hi,
Can anyone tell me the difference between "AHB-Lite Master" and "AHB-lite Mirrored Slave .It seems both are the same only the difference of hsel and hreadyIn signals .
thanks and regards ,

Arj,
I believe that these are descriptions used in ARM's bus matrix blocks, so if you are using them you probably should be sending the questions direct to ARM's support teams.
From what I've seen, the names of the interfaces tell you exactly what they implement; an "AHB-lite Master" would generate an interface implementing an AHB-lite master that you could use to drive an external AHB-lite bus (so no HSEL and just one HREADY), and the "AHB-lite mirrored slave" would implement the mirror image of a slave interface so that you could directly connect a single slave (so an HSEL signal and 2 HREADY connections).
Which agrees with the signal differences you describe.
So choose the interface option that suits what you are connecting to.
