The TSMC 28-nm HPM (high performance for mobile applications) process technology that achieved these results addresses applications requiring both high speed and low leakage power. Using various design signoff conditions, ARM A9 at TSMC 28HPM delivers performance speed range from 1.5 GHz to 2.0 GHz, suitable for mobile computing, and up to 3.1 GHz for high-performance uses. With its wide performance-to-leakage coverage, the 28-nm HPM process was developed for devices targeting networking, tablet and mobile consumer product applications.
The ARM Cortex-A9 silicon implementation and validation is part of TSMC's ongoing technology benchmarking effort to demonstrate performance, power and area (PPA) capabilities at the system-on-chip (SoC) level for each process technology node.
"At 3.1 GHz this 28HPM dual-core processor implementation is twice as fast as its counterpart at TSMC 40nm under the same operating conditions," said Cliff Hou, TSMC Vice President, Research & Development.
The Cortex-A9 processor is available for license from ARM and is aimed at mobile, high-performance consumer, and enterprise SoC requiring high performance and low power.
