Nvidia's Tegra system-on-chip will allow portable devices to play high-definition video for more than 10 hours, an engineer from the company told the Hot Chips conference on Monday.
Nvidia announced the Tegra series in June, introducing the Tegra 600 and 650 chips and folding the previously announced APX 2500 cell-phone chip into the same line. The chips take Nvidia beyond its base of graphics processors and up against Intel's Atom platform. The 600 and 650 can be used with hard disk drives and are designed partly for MIDs (mobile Internet devices), an emerging category of pocket-sized computers that is also in Intel's sights with Atom.
"Power really is the challenge," said Michael Toksvig, a distinguished engineer at Nvidia, who spoke at the conference taking place this week at Stanford University. Advances in lithium-ion battery technology only extend the amount of power from one charge by about 5 percent per year, so the rest has to be made up with device efficiency and power management, he said. In high-definition video playback, a Tegra chip's power consumption is well below 200 milliwatts, he said. The chips, based on an Arm core, are as small as 12 by 12 millimeters for the APX 2500...........
