why in fixed burst the address is same for different transfer of the burst

[pkoti83]

For example in AXI protocol, we have

4 byte size of each transfer

4 transfers in burst.

why in fixed burst the address is same for different transfers of the burst in AXI protocol.

What is the use of it?

1st transfer address is 0x00

2nd transfer address is 0x00

3rd transfer address is 0x00

4th transfer address is 0x00

then may i know the Total size of memory for these 4 transfers.

Hi pkoti83,
Fixed burst type is used in FIFO where repeated accesses to the same location such as loading or emptying a FIFO can happen.
I can only think of FIFO being used as buffers. Wherein some delay can be added between the transactions.
Hope this helps.
