What if RFID, A minature CPU !?


Of course, Its a CPU based on Radio Frequency IDentification (RFID) Chip. If you still don't believe it, I have a proof. Scientists from University of Massachusetts are working on a Software that enables the computational capability of New RFID Chip. It was named "Memento", in accordance with the film "Memento" released in the year 2000. The Hero of this movie tries to reveal the mystery of his wife's death, with his rebooting brain for every five minutes. The same happens with the RFID. "We are working on software to make it possible to actually compute , given that our power is to be disappearing and reappearing" says Kevin Fu, Assistant Professor of computer science at the University of Massachusetts Amherst.

The new RFID Chip "Memento" carry 16Mhz Microprocessor, 512 Bytes of RAM and 8KBs of flash storage. It was Intel's prototype Wireless Identification and Sensing Platform (WISP), Kevin Fu and his work mates was using to develop their RFID Computing Software. To make it clear, The RFID doesn't carry any software and It was the computer software that makes the RFID to calibrate. So generally, a master computer can share the processing with this RFID Chip. The "Memento" is operated with three varying power stages.

1. Sleep - 0.2 - 2.5microwatts
2. Mid Range - 1.8 - 3.6mW - Performs read and Calibrations.
3. Active Range - 2.2 - 25.2mW - Perform Write operation in Flash memory.

Thinking on the purpose of this design, This new design can perform Cryptographic Calibrations in order to secure the data that it sends and receives in fine time. So what-else we can do with this "Memento" ! Every computer can be connected to network, "Memento" is too a Computer that can be used to perform network operations like PAN with the extension of applications to Smart Cloths, Appliances, etc.. Write me comment, about what we can do with this New Technology.
