ARM and Globalfoundries on Wednesday demonstrated a special test chip based on two ARM Cortex-A9 general-purpose cores operating at whopping 2.50GHz, which is a record clock-speed for ARM. The system-on-chip was made using 28nm HPP [high-performance plus] fabrication process.
In a bid to verify high-performance system-on-chip designs and their elements, ARM and Globalfoundries developed special TQV (technology qualification vehicles) that use Artisan advanced physical IP which is widely used by many developers. Each TQV is designed to emulate a full specification SoC and aims to improve performance, lower power consumption and facilitate a faster path to market for foundry customers. The dual-core Cortex-A9 TQV SoC operating at 2.50GHz is an industry record and a clear demonstration of 28 HPP fabrication process’ capabilities.
