Sony develops "Virtual Mobile EngineTM",
A new reconfigurable circuit technology for much lower power-consumption
Adopted in Network Walkman's LSI
Sony Corporation has developed low-power-consumption
dynamic reconfigurable circuit technology for compact mobile
devices, "Virtual Mobile EngineTM",
and incorporated this technology in a newly developed LSI
"CXR704060" for Network
Dynamic reconfigurable circuit technology does not require
multiple dedicated circuits for each operation. The technology
enables an LSI to function according to each situation by
altering its preset configuration and operation with software
during processing. Previously this technology was considered
only for use in large-scale data processing communications
devices requiring swift specification changes, but concerning
its application in consumer mobile devices, power-consumption
had been an issue.

Sony developed "Virtual Mobile EngineTM"
for audio visual LSIs as a solution to the increasingly
complex LSI design of the multi function consumer mobile
devices. The first product adopting the technology is the
"CXR704060" LSI for Network
Walkman "NW-MS70D", which achieved fourfold energy efficiency
(in playing ATRAC3) in comparison to the current commodity
DSP (Digital Signal Processor)*. In "CXR704060", reconfigurable
circuit technology is applied to energy consuming multiple
processes that decode the original music data from its compressed
form. This is the world's first application of low-power-consumption
dynamic reconfigurable circuit technology in consumer products.
By altering the process of LSI design, "Virtual Mobile EngineTM"
allows the manufacture of more compact, higher quality mobile
devices. In future, Sony will continue the pursuit of even
more distinctive mobile product design through the extensive
application of this "Virtual Mobile EngineTM".
