Stands for "Intellectual Property". Used like this, I believe it's a
bit of a slang. It's also slightly pejorative as we often assume that
self contained "IP Cores" are proprietary black box. But considering
all the security issues that was found in these black boxes firmwares,
it's kind of fair criticism.
