WebOct 9, 2024 · The ready/valid handshake. The AXI protocol implements flow control using only two control signals in each direction, one called ready and the other valid. The ready signal is controlled by the receiver, a logical '1' value on this signal means that the receiver is ready to accept a new data item. The valid signal, on the other hand, is ... WebMar 23, 2024 · A good example of such a master is my recent AXI-lite master for the “hexbus” debugging bus.This master uses the RREADY and BREADY signals as states in a state machine to know whether or not it is in the middle of a read or write cycle. Once the last acknowledgment is returned, the core returns to idle, lowers RREADY and BREADY, …

WebApr 20, 2024 · The AXI Stream protocol is a great way to move data around. Sure, like most AXI related protocols, it’s a bit bloated.However, if you remove everything but the TVALID, TREADY, TDATA and possibly TLAST or TUSER signals, then it really becomes quite usable. Indeed, it’s a great protocol for just moving raw data around.

Webvalid data or control information is available on the channel. The destination displays the READY signal to show when it can accept the data . Both the read data and write data channels display the LAST signal when it transfers the final data item.

WebAXI makes a distinction between transfers and transactions: A transfer is a single exchange of information, with one VALID and READY handshake. A transaction is an entire burst of transfers, containing an address transfer, one or more data transfers, and, for write sequences, a response transfer.
