The Maverick EP7309 is designed for ultra-low-power
applications such as digital music players, internet appliances,
smart cellular phones or any hand-held device that features the
added capability of digital audio decompression. The core-
logic functionality of the device is built around an ARM720T
processor with 8 KB of four-way set-associative unified cache
and a write buffer. Incorporated into the ARM720T is an
enhanced memory management unit (MMU) which allows for
support of sophisticated operating systems like Microsoft
Windows CE and Linux.
