Optimised SoC developed based on ARM Cortex-A series processors
1 min read
ARM and GlobalFoundries have developed an optimised SoC solution for ARM Cortex-A series processor designs using the former's Artisan advanced physical IP and the latter's process technologies.
The companies have announced the industry's first test chip based on a dual core Cortex-A9 processor operating at frequencies of more than 2.5GHz. In addition, a 20nm tape out using GlobalFoundries' Technology Qualification Vehicle (TQV) has been announced for SoCs based on Cortex-A9 processors.
The two companies have worked together to develop a TQV strategy that enables GlobalFoundries to optimise its advanced process technology for designs based on Cortex-A series processors. Each TQV is designed to emulate a full specification SoC and aims to improve performance, lower power consumption and make it easier to market for foundry customers.
Simon Segars, ARM's executive vice president and general manager, physical IP division, pictured, said: "These milestones are proof that the strategic collaboration involving Cortex-A series processors implemented using Artisan advanced physical IP and GlobalFoundries' 28nm process technology is able to deliver leading high performance, energy efficient solutions. Furthermore, it serves as a foundation for next generation mobile and high end consumer devices using 20nm process technology."
The 2.5GHz performance results are based on multiple wafers running in GlobalFoundries' Fab 1 in Dresden, Germany, on the company's 28nm HP technology. The company says an additional performance increase, compared to 28nm HP, is expected on its 28nm High Performance Plus platform for wired networking applications, with low active power and an operating point of 0.85V.
The 20nm TQV is based on GlobalFoundries' 20nm LPM platform, which it claims improves performance by up to 35% and nearly half the power consumption of 28nm technologies. The goal of the 20nm TQV is to develop process technology that is optimised for Cortex-A series processors. According to GlobalFoudries, the early collaboration between the two companies will help chip designers address the increasing design and manufacturing complexities of 20nm technology, while reducing time to volume production.
GLOBALFOUNDRIES' HPP and LPM SoC design platforms are all based on the company's production-proven 32/28nm HKMG technology and are fully enabled with ARM standard cell libraries, memory compilers and IP from a variety of third party providers.
