LONDON – Foundry Taiwan Semiconductor Manufacturing Co. Ltd. has announced it has made a dual-core ARM Cortex-A9 processor test chip in its 28-nm high-performance mobile CMOS process that it has run at a 3.1-GHz clock frequency under typical operating conditions.
TSMC (Hsinchu, Taiwan) said that this achievement demonstrates that the 28-nm HPM process is ready for use in a broad range of mobile, consumer and enterprise applications.
For mobile application signoff conditions the 28HPM process delivers clock frequencies in the range 1.5-GHz to 2.0-GHz, TSMC said. But for high performance requirements it can be run up to 3.1-GHz the company said. This could either for very short term use or where power consumption is less critical because a system is connected to a main supply of electricity.
The 28HPM implementation runs twice as fast as the 40-nm counterpart made by TSMC under the same operating conditions, according to Cliff Hou, vice president of R&D at TSMC.
Finally, there is real speed in ARM land! I can't wait to see these on the market and on Small Board Computers for use in robotics. If nothing else they would be nice to have for those cpu sucking applications like: FP or Vision.
Any paper that supports your case. I know that at 28nm your static power become a huge issue. The dynamic power is a function of the high freq. That is what you pay for the high speed. Unless you can explain that it is not related to freq but process, I think this product could go into mobile devices.
At 3.1Ghz this consumes more power and is use full with a system connected to power or for a short time usage with batteries. So much also the heat dissipated in this chip.The cooling system got to be efficient and i feel this is more suitable to desk top items rather than handheld appliances at 3.1Ghz.
