6 VME
The VME (Virtual Mobile Engine) is a reconfigurable processor to decode
audio/video. in 2002, Sony developed the Virtual Mobile Engine? as
a method for achieving significant power reductions and miniaturization
in LSIs for audio/visual products. This circuit technology, which
can reduce power consumption by approximately 1/4 over conventional
general-purpose digital signal processors (DSP), was adopted for use
in the CXR704060 LSI used in the Network Walkman "NW-MS70D".
There are minimal system APIs for the VME (disable/enable reset).
It appears the VME software is tied into the ME (Media Engine).
