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.
