Dunno about that JVM, but aJile's aJ-80 and aJ-100 Java CPU chips were designed with realtime Java in mind and don't have caches in the normal sense. (They do have on-chip RAM, and I think that current versions of the firmware for J2ME use some of it as a stack cache, but that's not quite the same). Thomas Maslen maslen@pobox.com
