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
