The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Looking to implimenting an autocorrelation function (ACF) into one of my projects.
Have you considered this article? It goes over the basics of the autocorrelation function, while also illustrating how you can build one with a Wishbone interface. Further, the Verilator logic for this function is kept and maintained on github here. Sure, it uses Wishbone. If you want to use AXI you can either use a bridge, or rework the the interface (it's not that hard ...).

Professional or Hobby?
I marked as "both" above, but one might argue that my "hobby" designs are more "Internal Research and Development" (IR&D) than just hobby. Everything has a purpose. Today's hobby design may be used in tomorrow's paying project. Examples include the both the ZipCPU and its subcomponents, my AXI work, DSP filters, PLLs, FFT and much more--all of which have found their way into a variety of customer designs.

Digital Loop Filter for Digital PLL Design
Are you interested in an all-digital solution? If so, I have a couple of digital PLL's you might want to check out. These are the PLL's I use if I want to demodulate a digital signal in hardware, as demonstrated by this example. If what you are looking for is a mixed digital/analog solution, then ... I don't have an example.
