More innovation is needed for more functions

PC link? Integrating the DSP with the

MCU for cost saving Sharing the Flash Storage

with other devices (as a Flash disk?)

Flash memory cost becomes the dominated item as longer speech length is needed

Telecom / Wireless Headset 2.4G digital link Gross 1Mbps with effective data rate of

600/700kbps The high data rate will allow for multi-users

using the same channels at the same time without interference

Bluetooth compatible is the current main stream

Non-bluetooth compatible is another alternative choice for a lower cost solution

AV / MP3 Flash-based MP3 Player Multi-lingual, display shows songs

and singer name USB1.1 (12Mbps) PC link for fast MP3

songs download Digital voice recorder mode using the

Flash storage The superior audio quality for voice

provides the opportunity to configure a MP3 player as a Language Learning Centre

More innovation can come out with more ideas

LSI integration is needed
