Dear Forum,
Can someone please clarify my 2 questions:
a)
Why in AXI lite protocol there is no tlast port?
Mainly AXI lite consists of AXI-stream protocols, but there is no tlast port in AXI lite. Can someone justify what was the reason of not including the tlast port in AXI-lite.
b)
Can AXI stream tready stay high after handhsake happens?
When tvalid is high and tready also goes high, that means handshake occurred and data transfered from master to slave. So after that handshake can tready still stay high, meaning that it can receive new data? Usually after all handshake events tready goes to low.
Thanks
Hayk
