OVERVIEW

The Cirrus Logic CL-PS7500FE is designed to be

used in internet appliances such as the network

computer, smart-TV, intranet terminal, screen

phones, DVD players, and so on.

The massively integrated CL-PS7500FE offers a

complete system-on-a-chip solution that includes a

32-bit ARM CPU with cache and MMU, CRT and

LCD controller, memory controller, FPU, CD-quality

sound controller, interface to the Cirrus Logic DSP

device for 56K modem and speakerphone, and a

PC-type I/O bus. To handle streaming of audio and

video data on the Internet, the CL-PS7500FE

includes a double-precision FPU to accelerate

software codecs.
