It is rare to use ADI's DSP, but it is impossible to say that it has never been touched.
This semester, the lab came with a fingerprint machine to strictly control our attendance. We are hateful and always wonder how to break it. Suddenly came to the mood, I invited the younger brother to dissect this stunner together. Unexpectedly, it turned out to be the DSP of ADI, which is estimated to be used for image processing of fingerprints. Checked on the Internet, this is a very mature DSP core board, sold in bulk separately, the price is quite cheap. One day, there are meters, and I have to go into a study to study.
Finally, the Spring Festival is just around the corner, I wish you all the best!
