[moved] Information needed for slave addressing from master...

[muthu7495]

Hi All,
I am having 256 bit data width and 64 bit address width avalon bfm master and 512 bit data width 30 bit slave.In between i have one interconnect.
The base address is 64'h 0000_0010_0000_0000(Byte addressable) .while i am sending the data to the 512 bit slave next address range is what?

Is it 64'h0000_0010_0000_0040 or 64'h0000_0010_0000_0020 ? Which data width i have to take master or slave ...

Please someone guide me .


Thanks
Venkat

Well Avalon uses byte addressing so for 512-bit data you should have the next 512-bit data offset every 0x40 (byte) addresses.

Thanks for your reply. Actually master data width is 256 so we can send maximum 256 bit data. If we want to send 512 bit data i have to follow 0x20 .
Is it correct ? I am getting confuse with this.

How can i send 512 bit data to the slave from the master(256 bit data width)



Thanks

The address is always in bytes wont mater if you have a 32-bit master or a 1024-bit master.
