Sony Virtual Mobile Engine (VME): The Secret of the Network Walkman's Stamina
Ever wonder why your Network Walkman has higher playback time than other DAPs? The huge improvement in battery life is a result of Sony’s VME (Virtual Mobile Engine) technology – an integrated circuitry system that reduces energy consumption by approximately 80%. This technology was integrated since 2003 with the NW-MS70D.
According to Sony, the VME is a new reconfigurable circuit technology for much lower power-consumption adopted in Network Walkman’s LSI. This technology achieves both multifunctional/flexibility and low power consumption by transforming the LSI internal circuit structure repeatedly according to the function (purpose) desired.
The CXR704060 is a low-power LSI that includes a VME and is based on Sony’s SoC (System on a Chip) technology. At the same time as having a major impact, those characteristics have resulted in the device being accepted by the audio market.
The NW-E405 Network Walkman® has attracted much interest since its release on April 21, 2005. While its ability to provide up to 50 hours* of continuous playback has been one reason for its popularity, it is its CXR704060 with an on-chip VME that makes this stamina possible.
The Network Walkman uses software programming to support not only different audio compression formats such as ATRAC3, ATRAC3plus, and MP3, but a wide range of sound effects as well. Furthermore, the CXR704060 achieves an LSI power consumption during audio playback (ATRAC3 playback) of roughly one quarter to one fifth of that of earlier LSIs.
At the same time as aiming for even further evolution of the VME, Sony is also working on concrete business plans for other LSIs that could include the VME. Keep your eye on Sony’s VME, which radically increases flexibility for conceiving of and developing new mobile products.
*When using the internal rechargeable battery, ATRAC3 at 105 kbps, and normal power saving mode.
