PC-based Control, Software and Bus Trends(Table 5-2). The Palm family of hand-held devices uses MotorolaDragonBall EZ chips.Tables 5-2. Device Trends———————————————————————————• Samsung CDMA watch/phone is a small wireless phone• Internet refrigerator from Frigidaire and ICL has Internetaccess and bar-code scanner to track contents• Ericsson R380 mobile phone runs on EPOC OS, withvoice dialing and Internet access————————————————————————————Some low-cost embedded processors compare with Intel Pentiums,except that the embedded processors cost less and consume less power.Stanford University’s School of Engineering believes that embeddedchips may be first to offer multiple processors on a single chip.IBM has a prototype of its cyberphone. This is a combination cellularphone and computer with wireless Web access. It has a small builtindisplay which uses a mirror to enlarge images to the same size as theywould appear on a desktop monitor.IBM is also working on a super-high-resolution wrist watch thatcan provide easy visual access to data. Wrist phones are available fromSamsung with voice-activated dialing.Symbian is a consortium of Ericsson, Motorola, Nokia, and Psionthat developed the EPOC operating system for Internet devices.Symbian is developing secure wireless devices and Web surfing phoneswhich are souped-up cell phones that provide access to the Internet.The Ericsson R380 GSM mobile phone will run on EPOC and includea built-in modem, PDA, touch screen, calendar, address book, e-mail, Internet connection, handwriting recognition, voice dialing andvoice answering.Smarter microprocessors are also being used in refrigerators. Aprototype refrigerator from Frigidaire Home Products and ICL, uses anIntel microprocessor along with 32MB of RAM, an Ethernet connection,flat-panel touch screen, bar-code scanner and Microsoft Windows.
