    Faster-Than-Realtime :-)

    The Maverick EP9312 is a member of Cirrus Logic's high integration system-on-chip family of devices intended to enable cost-effective home audio jukeboxes and servers. The EP9312 combines the powerful new 200 MHz ARM920T processor core, Cirrus Logic�s new MaverickCrunch math co-processor, patent-pending MaverickLock security technology, and a broad range of peripheral devices for product design flexibility. The ARM920T microprocessor core with separate 16 KByte, 64-way set-associative instruction and data caches is augmented by the MaverickCrunch co-processor, enabling faster-than-realtime compression of audio CDs. The proprietary MaverickLock
