It would never be 1 core per chip. That's about 15 years ago in processor design time.
Thanks for your history lesson, but I am referring to the "soft" mining core in the Programmable logic block of the Zynq-7000 discussed in the article. Not hard-wired CPU cores.

They referenced utilizing multiple mining cores connected to the embedded bitcoind node, but they did not expand on if they were able to create multiple soft cores on a single Zynq-7000.
Just a curiosity. As it would need about a 100 cores just to equal the hashing power of a USB block erupter. hahaha!
