ARM A73 processor optimised for ‘immersive mobile experience’
In its latest release, ARM has announced mobile processor and graphics-unit technologies that it has optimised for applications tasks such as virtual reality (VR) and augmented reality (AR) on forthcoming high-end mobile devices. The ARM Cortex-A73 processor and the ARM Mali-G71 graphics processor offer sustained performance and efficiency gains that will lead to new products with enhanced contextual and visual capabilities. This will allow devices to run high resolution content for longer periods while staying within strict mobile power budgets.

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.
