ARM adds that at under 0.65 mm² per core (on a 10nm FinFET process technology) the Cortex-A73 is the smallest and most efficient 'big' ARMv8-A core. Its advanced mobile microarchitecture enables a 30% uplift in sustained performance and power efficiency over the Cortex-A72. Size and efficiency improvements enhance the ability of silicon providers to use the Cortex-A73 in ARM big.LITTLE configurations. These improvements create further opportunities for designers to scale big cores along with the GPU and other IP in a single SoC. Ten partners have licensed the Cortex-A73 so far, including HiSilicon, Marvell and Mediatek.
Cadence Design Systems, in a parallel announcement, is supporting this core release with rapid adoption kits based on a 10nm reference [design] flow. Cadence says the kits (RAKs) are based on the latest digital implementation and signoff technologies optimized to work with ARM Artisan physical IP and ARM POP IP for ARM Cortex-A73 and ARM Mali-G71.
According to Cadence, ARM used its digital and signoff tools to design the ARM Cortex-A73 CPU and the ARM Mali-G71 GPU, resulting in a reference flow from which the RAKs are derived; the collaboration enables designers to achieve overall PPA (power/performance/area) goals with Cadence digital, signoff, and system and verification tools optimized for Cortex-A73 based designs.
