I would like to know what's the meaning of:
ap, as in ap_clk
phi, as in data1_phi
fu, as in grp_fu
terms that we see in the Analysis view of tools like Vivado HLS.
I guess fu may be for "functional unit", but I'm quite not sure.

Vivado_hls creates ap_clk. When the top level function is synthesized the arguments or parameters to the function are synthesized into RTL ports. Can you please let us know where did you get the signals with names _phi and _fu.

-- edit: added the missing reference
My two cents about
> ap, as in ap_clk
Xilinx VivadoHLS tool originates from the AutoPilot tool from AUTOESL
Xilinx acquired AUTOESL in 2011 (ref)
So I guess "ap" is inherited from AutoPilot.
