Probably the explanation is here (on the first page): http://www.arm.com/pdfs/DVI0035B_926_PO.pdf There are lots of other interesting docs at http://www.arm.com by the way. ___ maemo-developers mailing list maemo-developers@maemo.org https://maemo.org/mailman/listinfo/maemo-developers

My uneducated guess is that it means Jazelle, which are Java extensions for ARM. From what I've seen on various mailing lists, the exact details of Jazelle are a seekrit (ooh!) for which you must sign an NDA with ARM Ltd. Sadly that precludes most open source uses of it.
