Hi, I'm a graduate student living in south Korea. I'm studying about AMBA 3.0 AXI.
Recently, I read "AMBA AXI Protocol.pdf". but i have two questions about AXI after reading.
Firstly, i very wonder AWID, WID and BID when write transaction is started.
We assume that two masters(M0, M1-1bit ) and two slave(S0, S1) are.
The M0 master want to send the burst data to the S0 slave. the M0 master can generate the AWID( value : 0x0001 ). at that time, the M0 master must generate the WID corresponding AWID. I wonder this situation. is the WID value? simply, does the WID value have the same AWID value ( 0x0001) ? also, is the RID value? similarly, does the RID value have the same AWID value ( 0x0001) ?
Secondly, we assume that burst transaction is started.
Do WID and RID have to be generated whenever one of burst data is transferred or only one about all of the burst ?
I totally want to know about the situation.
Dear. Yasuhiko Koumoto
Thank you for your solutions whenever i ask the AMBA 3.0 AXI.
i will enter the master's degree. so i don't have a lot of information about AXI.
Whenever i encounter the problem, i visit ARM community. And i post my problem on the community.
you are very kind, polite and good! your response is very helpful to me!
