Since Quark and Z3000 are pre-released products, I have escalated your questions to an Intel representative in your area and soon you should be contacted directly. You may be interested in a Bay Trail webinar coming up on October 9, 2013. The webinar is titled, "Intel(r) Atom(tm) Processor SoC: A versatile solution for Intelligent Systems.
