OVERVIEW

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
