Globalfoundries and ARM have revealed a multiyear agreement that aims to deliver optimized SoC solutions for ARM processor designs on Globalfoundries' 20nm and FinFET process technologies. According to them, the agreement extends their previous collaboration to include GPUs, which are becoming an increasingly critical component in mobile devices, the companies added.

As part of the agreement, ARM will develop a full platform of ARM Artisan Physical IP, including standard cell libraries, memory compilers and POP IP solutions. The results will help enable a new level of system performance and power-efficiency for a range of mobile applications, from smartphones to tablets to ultra-thin notebooks.

The companies have been collaborating for several years to jointly optimize ARM Cortex-A series processors, including multiple demonstrations of performance and power-efficiency benefits on 28nm as well as a 20nm test-chip implementation currently running through Globalfoundries fab in Malta, N.Y. This agreement extends the prior efforts by driving production IP platforms that will enable customer designs on 20nm and promote rapid migration to 3D FinFET transistor technology. This joint development will enable a faster time to delivering SoC solutions for customers using next-generation ARM CPUs and GPUs in mobile devices.

Globalfoundries plans to develop optimized implementations and benchmark analysis for next-generation, energy-efficient ARM Cortex processor and ARM Mali graphics processor technologies, accelerating customers' own SoC designs using the respective technologies. The comprehensive platform of ARM Artisan Physical IP for Globalfoundries' 20nm-LPM and FinFET processes and POP IP products provide fundamental building blocks for SoC designers. This platform builds on the existing Artisan physical IP platforms for numerous Globalfoundries' process technologies including 65nm, 55nm, and 28nm, as well as the Cortex-A9 POP technology for 28nm SLP, now available for licensing from ARM.

ARM POP technology accelerates the core hardening for ARM's Cortex-A series CPUs. POP IP products are comprised of three critical elements necessary to achieve an optimized ARM core implementation. First, it contains Artisan physical IP standard cell libraries and memory cache instances that are specifically tuned for a given ARM processor and foundry technology. Second, it includes a comprehensive benchmarking report to document the exact conditions and results ARM achieved for the processor implementation across an envelope of configuration and design targets. Finally, it includes the detailed implementation knowledge including floor plans, scripts, design utilities and a POP Implementation Guide, which enables the end customer to achieve similar results quickly and with lower risk.

The Globalfoundries 20nm-LPM technology is a comprehensive, cost-effective platform, delivering up to 40 percent performance improvement and twice the gate density of 28nm, noted the company. Since it will offer a range of transistor capabilities, 20nm-LPM will serve a broad range of power and performance points across high-volume market segments. By offering a full scaling of the transistor and metal pitch, the resulting 20nm-LPM devices will be highly competitive in cost and area to suit the requirements of next-generation devices.
