Computer Engineers Double Cell Phone Memory with Software
|Computer engineers at Northwestern University and NEC Laboratories America, Inc. are the first to do what many thought impossible; they have developed technology that doubles the usable memory on cell phones and other embedded systems without any changes to hardware or applications. Embedded systems are computers within devices not generally considered to be computers, such as cell phones, cars, iPods, medical devices and digital cameras. The improvement was made in the operating system software alone.|
This innovation, the result of two years of close collaboration between researchers at Northwestern and NEC Labs, is featured in millions of new smartphones, the NEC-manufactured FOMA N904i, which first hit shelves in Japan this summer.
In early 2004, NEC Labs researchers conceived the concept of integrating compression technologies into the operating system itself to provide compression as an operating system service.
The idea was to transparently compress and decompress selected regions of memory (both code and data) to drastically reduce the memory footprint of embedded applications.
NEC Labs entered into a strategic partnership with Northwestern to jointly develop this idea. The team consisted of Dick, his first doctoral student, Lei Yang, and Haris Lekatsas and Srimat Chakradhar from NEC Labs America. (Read more of news report)
