[MOVED] any VHDL code available that implement PCA?

[jmatsushita]

Hi there,

I'm wondering whether there is any VHDL code available that implement PCA?

Thanks,

Jun

Have you tried looking on opencores.org ?

One should not use abbreviations unless they are well known outside the group that uses them... e.g. VHDL, JTAG, PCI, etc

PCA.
Google comes back with the following:
1. Principal Component Analysis
2. Porsche Club of America
3. Presbyterian Church in America
4. PCA Skin Professional Skin Care Products & Aesthetician
5. PCA Engineering: Cathodic Protection Testing & Solutions
6. PCA Engineering

I suspect none of these are related to what you are looking for.

Tricky,

As you're pointing the OP to opencores, maybe you know what PCA stands for?

Hi there,

this was my first post so apologies for not knowing about the rules. Yes PCA is Principal Component Analysis. I have found a research paper (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3230973/pdf/sensors-10-09232.pdf) that discusses the implementation of PCA with an FPGA for image recognition purposes but there's not code. I shot an email to the author and if he replies I will share the answer here.

Yes I had looked at OpenCores, and nothing as complex as PCA.

FYI, I'm looking into this for the purpose of developing a water sensor that uses acoustic classifying to help measure water consumption in the home. https://iilab.org/projects/open-droplet.html

Cheers,

Jun

Well searching for "PCA IP core" came back with the first hit for "PCA" and this is a paper on doing a Zynq design. Maybe you can contact the authors.

That's interesting ads-ee, even if it's not using an FPGA, I should surely look into this alternative thanks!

Nope. But with a question as vague and lazy as the OPs, it's my stock answer.

Lovely. Hope my further posts make it clearer?

Zynq is an FPGA with an embedded dual core ARM. So it's probably a hybrid SW/HW implementation (but that's just an educated guess), otherwise why use the Zynq part?
