Coming with nanometer-scale process technology and green-movement of consumer electronics, the methodology of low power-oriented design takes place in the cutting edge implementation needs. Socle's Multi-supply Multi-voltage (MSMV) design approach accommodates multiple power domains and multiple voltage levels, which makes low-power chip design much more complicated than the design of normal chip.

The challenges that MSMV implementation design needs to overcome in advanced process nodes:

• Timing
• Power
• DFT
• PD
• DFM
• DFY

Socle's low power solution, MSMV, has following features:

• ARM standard and PMK library based
• Multiple power domains inside
• Multiple power supplies for chip core cell
• Multi-Vth optimization
• Level shifter implemented
• Isolation cell implemented
• Retention cell implemented
• Power gating cell implemented (internal power shut off)

Socle's MSMV solution meets the most up-to-date demand of ultra low power for consumer electronics, such as:

• Mobile Internet Device (MID)
• Netbook / Smartbook
• Personal Media Player (PMP)
• GPS
• Smart Phone
• MP3 / MP4
• e-Book
• Digital Camera
• Other mobile / handheld devices

Ultra Low Power; Ultra High Performance

Comparing two same SoCs with only one difference, one with MSMV design and the other without it, the power consumption of the SoC with MSMV could be greatly reduced to one-fiftieth (1/50) maximum of the one without MSMV in leakage power. As for dynamic power, it saves up to 70% power consumption in average under regular using situation.
