ARM Introduces 64-Bit Processor Series, With Support For 32-Bit

A new 64-bit processor series that will also be capable of handling 32-bit operations has been announced by ARM. The new Cortex A50 processor series currently consists of the Cortex-A57 processor and the less powerful Cortex A53 processor, which will let ARM partners create system-on-chips that are capable of operating a wide range of devices including traditional mobile devices and even servers.

The new Cortex A50 series of chips are based on the ARMv8 architecture, which allows them to tackle both 64-bit and 32-bit ecosystems. At the same time adaptability is further improved with the use of a technique that ARM calls “big.LITTLE.” This technique is a way of setting up the SoC where in both the Cortex A57 chip and the Cortex A53 are combined. Cortex A57 is more powerful and is suited to be used on servers but naturally it also requires more power. Cortex A53 is more suited to handle low intensity workload and is also a lot more power efficient. With these two chips combined in a single package a hybrid processing unit is produced that is power efficient and which can handle high intensity processing.

Major players in the chip industry have already licensed the new ARM product. These include AMD, Broadcom, Calxeda, HiSilicon, Samsung and STMicroelectronics. However, these new chips are at least a couple of years away from powering smartphones and tablets.

ARM Cortex-A50 processor series:

  • Currently includes the Cortex-A57 and Cortex-A53 processors
  • Optional cryptographic acceleration that can speed up authentication software up to x10
  • Interoperability with ARM Mali™ graphics processor family for GPU compute applications
  • Features AMBA® system coherency to extend to many-core coherence with ARM CoreLink cache coherent fabric components, including the CCI-400 and CCN-504

ARM Cortex-A57 processor:

  • The most advanced, highest single-thread performance ARM application processor
  • Delivers the enhanced performance required for smartphones as they continue to transition from content-consumption devices to content-creation devices, with up to three times that of today’s superphones in the same power budget
  • Provides computer performance comparable to a legacy PC, while operating in a mobile power budget, enabling cost and power efficiency benefits for both enterprise users and consumers
  • Extended reliability and scalability features for high-performance enterprise applications

ARM Cortex-A53 processor:

  • The most efficient ARM application processor ever, delivering today’s superphone experience while using a quarter of the power
  • Incorporates reliability features that enable scalable dataplane applications to maximize performance per mm2 and performance per mW
  • Optimized for throughput processing for modest per thread compute applications
  • The Cortex-A53 processor combined with the Cortex-A57 and big.LITTLE processing technology will enable platforms with extreme performance range while radically reducing the energy consumption
