4.4.1. Full-Raster TREADY Handshake Process

AMBA AXI4-S protocol specifies that the TVALID and TREADY handshake determines when information passes across the AXI4-S interface. For more information, refer to Data Exchange .

A two-way flow control mechanism enables both the transmitter and receiver to control the rate at which the data and control information is transmitted across the interface. For a transfer to occur both the TVALID and TREADY signals must be asserted. Either TVALID or TREADY can be asserted first, or both can be asserted in the same ACLK cycle.
