Plugcomputer

What is a Plugcomputer ?

A plug computer is a tiny, low power server, intended to provide network-based services within the home. It is an always-on system, and can serve data and applications to computing devices within the home. It can also be a bridge between home computing devices and Internet-based services.

The GUI Plug SD card allows SheevaPlug to boot into Debian Squeeze with Gnome Desktop installed and ready to connect your mimo monitor, 4Gb and 8Gb SD cards with GUI Plug preinstalled are available. Connection to the home network is via Gigabit Ethernet, and offers desktop class performance. - From

MOSIS - Affordable Integrated Circuits Fabrication

MOSIS Is An Multi-Project Wafer (MPW) Integrated Circuit (IC) Fabrication Service Provider.

MOSIS - Affordable Integrated Circuits Fabrication

"MOSIS is operated by the Information Sciences Institute at the University of Southern California (USC). MOSIS merges multiple IC designs submitted by both companies and universities onto multi-project wafers (MPW) to share the cost of fabrication among multiple users."

MOSIS - Affordable Integrated Circuits Fabrication

MOSIS - Metal Oxide Semiconductor Implementation Service

MOSIS keeps the cost of fabricating    prototype quantities low by aggregating multiple designs onto one mask set. This allows customers to share overhead costs associated with mask making, wafer fabrication, and assembly.

MOSIS Design Reference

A variety of design flows (digital, analog, mixed-signal) can be used with a number of different CAD tools, technology files, design kits, libraries and IP to create designs for processes accessed by MOSIS.
