Read data interleaving in axi

WebAt a master interface, read data from transactions with the same ARID value must arrive in the order in which the master issued the addresses. Data from read transactions with different ARID values can arrive in any order. Read data of transactions with different ARID values can be interleaved.. A slave must return read data for a sequence of transactions … WebJun 24, 2024 · The key features of the AXI protocol are: • separate address/control and data phases. • support for unaligned data transfers, using byte strobes. • uses burst-based transactions with only the start address issued. • separate read and write data channels, that can provide low-cost Direct Memory Access (DMA)

WebIf both transactions arrive at the AXI slave simultaneously, the behavior depends on the slave. For a dual-port RAM, you could conceivably read while writing to the same address. … WebIf the transaction is indicated as "non-modifiable," and both the Read and Write commands use the same ARID/AWID, the order must be preserved. This doesn't cover the case of simultaneous Read and Write commands, which is certainly possible for AXI. Here's some additional info I found in section A4.3.2 of the AXI Spec (ARM document IHI 0022F.b). so much beauty in dirt https://umbrellaplacement.com

WebNov 28, 2024 · AXI Read Transaction From here, the rest of the transaction occurs on the read data channel. When the master is ready for data it asserts its RREADY signal. The slave then places data on the RDATA line and asserts that there is valid data (RVALID). In this case, the slave is the source and the master is the receiver. WebThe interleaving of write data with different IDs on the W channel was permitted in AXI3, but is deprecated in AXI4 and later. Transactions with different IDs can complete in any order. …
