The Maverick™ EP7311 is designed for ultra-low-power

applications such as PDAs, smart cellular phones, and

industrial hand held information appliances. 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 Linux
