Feature Summary - 3.0 English

v_axi4s_remap supports mapping of AXI4S stream video data between 1,2 and 4 PPC modes. For enabling the feature of PPC conversions, “Convert Samples per clock” needs to be selected in the GUI of the IP.

This IP has two register configurable values namely, “inPixClk” and “outPixClk” (as mentioned in Register Details section), which specifies the PPC on input and the PPC required on output respectively. These values are used by the IP for remapping between various PPCs.

In all the PPCs, first pixel is aligned to the lower significant part of video AXI4S stream’s TDATA. For example, in 4PPC mode

vid_in_axis_tdata / vid_out_axis_tdata = {pixel3, pixel2, pixel1, pixel0}

v_axi4s_remap does not manipulate the component order in each pixel as it only alters the number of pixels per clock. Hence, the DisplayPort specific input component ordering on v_axi4s_remap is preserved on the output of the IP.

Also, BPCs does not matter for re-mapper module as it only manipulates video data bits in terms of pixels. Hence, all the BPCs are supported by this IP.
