The research team at the center has led several efforts, including the design and implementation of the 405LP ultra-low power embedded PowerPC processor, and the prototype of the Super Dense Server, an energy-efficient computing cluster.
Called the IBM PowerPC 405LP, the chip's innovations make it ideal for battery-powered portable consumer electronic devices.
The 405LP reduces active power by dynamically scaling processor performance to the level required to support the application.
Using IBM's custom chip-making techniques, additional features can also be added to the PowerPC 405LP to adapt the device to other applications.
