OVERVIEW
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
