OVERVIEW

The Cirrus Logic

portable and line-powered applications such as portable

consumer entertainment devices, home and car audio juke box

systems, and general purpose industrial control applications, or

any device that features the added capability of digital audio

compression & decompression. The core-logic functionality of

the device is built around an ARM720T processor with

8 kBytes 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

CE and Linux
