AXI4-Stream width converter
Maturity simulatedTargets FPGA + ASICDifficulty EasyPriority 1
AXI4-Stream data-width converter for integer ratios: upsizing packs R narrow beats (closing early on TLAST with cleared TKEEP), downsizing splits wide beats and drops trailing null beats of the final beat; equal widths give a register stage.
Simulated. The RTL is lint clean and passes its self-checking testbench against a reference model in simulation. It has not been run on an FPGA board or in silicon.
