Protocol Support

AVL-AXI-STREAM supports all AXI STREAM features including AMBA5 protocols with all optional signals.

For full details see AXI-STREAM Documentation.

Interface signals list

Signal	Source	Width	Description
ACLK	Clock	1	ACLK is a global clock signal. All signals are sampled on the rising edge of ACLK.
ARESETn	Reset	1	ARESETn is a global reset signal.
TVALID	Transmitter	1	TVALID indicates the Transmitter is driving a valid transfer. A transfer takes place when both TVALID and TREADY are asserted.
TREADY	Receiver	1	TREADY indicates that a Receiver can accept a transfer.
TDATA	Transmitter	TDATA_WIDTH	TDATA is the primary payload used to provide the data that is passing across the interface. TDATA_WIDTH must be an integer number of bytes and is recommended to be 8, 16, 32, 64, 128, 256, 512 or 1024-bits.
TSTRB	Transmitter	TDATA_WIDTH/8	TSTRB is the byte qualifier that indicates whether the content of the associated byte of TDATA is processed as a data byte or a position byte.
TKEEP	Transmitter	TDATA_WIDTH/8	TKEEP is the byte qualifier that indicates whether content of the associated byte of TDATA is processed as part of the data stream.
TLAST	Transmitter	1	TLAST indicates the boundary of a packet.
TID	Transmitter	TID_WIDTH	TID is a data stream identifier. TID_WIDTH is recommended to be no more than 8.
TDEST	Transmitter	TDEST_WIDTH	TDEST provides routing information for the data stream. TDEST_WIDTH is recommended to be no more than 8.
TUSER	Transmitter	TUSER_WIDTH	TUSER is a user-defined sideband information that can be transmitted along the data stream. TUSER_WIDTH is recommended to be an integer multiple of TDATA_WIDTH/8.
TWAKEUP	Transmitter	1	TWAKEUP identifies any activity associated with AXI-Stream interface.
