The ARM Cortex-A5 is a 32-bit processor core licensed by ARM Holdings implementing the ARMv7-A architecture announced in 2009. [1]
The Cortex-A5 is intended to replace the ARM9 and ARM11 cores for use in low-end devices. [1] The Cortex-A5 offers features of the ARMv7 architecture focusing on internet applications e.g. VFPv4 and NEON advanced SIMD. [2]
Key features of the Cortex-A5 core are:
Several system-on-chips (SoC) have implemented the Cortex-A5 core, including:

ARM is a family of RISC instruction set architectures for computer processors, configured for various environments. Arm Ltd. develops the architectures and licenses them to other companies, who design their own products that implement one or more of those architectures, including system on a chip (SoC) and system on module (SOM) designs, that incorporate different components such as memory, interfaces, and radios. It also designs cores that implement these instruction set architectures and licenses these designs to many companies that incorporate those core designs into their own products.
ARM11 is a group of 32-bit RISC ARM processor cores licensed by ARM Holdings. The ARM11 core family consists of ARM1136J(F)-S, ARM1156T2(F)-S, ARM1176JZ(F)-S, and ARM11MPCore. Since ARM11 cores were released from 2002 to 2005, they are no longer recommended for new IC designs, instead ARM Cortex-A and ARM Cortex-R cores are preferred.
The ARM Cortex-A15 MPCore is a 32-bit processor core licensed by ARM Holdings implementing the ARMv7-A architecture. It is a multicore processor with out-of-order superscalar pipeline running at up to 2.5 GHz.
The ARM Cortex-A8 is a 32-bit processor core licensed by ARM Holdings implementing the ARMv7-A architecture.
Exynos, formerly Hummingbird (Korean: 엑시노스), is a series of ARM-based system-on-chips developed by Samsung Electronics' System LSI division and manufactured by Samsung Foundry. It is a continuation of Samsung's earlier S3C, S5L and S5P line of SoCs.
The ARM Cortex-A7 MPCore is a 32-bit microprocessor core licensed by ARM Holdings implementing the ARMv7-A architecture announced in 2011.
Scorpion is a central processing unit (CPU) core designed by Qualcomm for use in their Snapdragon mobile systems on chips (SoCs). It was released in 2008. It was designed in-house, but has many architectural similarities with the ARM Cortex-A8 and Cortex-A9 CPU cores.
Qualcomm Krait is an ARM-based central processing unit included in the Snapdragon S4 and earlier models of Snapdragon 400/600/800 series SoCs. It was introduced in 2012 as a successor to the Scorpion CPU and although it has architectural similarities, Krait is not a Cortex-A15 core, but it was designed in-house. In 2015, Krait was superseded by the 64-bit Kryo architecture, first introduced in Snapdragon 820 SoC.
The ARM Cortex-A57 is a central processing unit implementing the ARMv8-A 64-bit instruction set designed by ARM Holdings. The Cortex-A57 is an out-of-order superscalar pipeline. It is available as SIP core to licensees, and its design makes it suitable for integration with other SIP cores into one die constituting a system on a chip (SoC).
The ARM Cortex-A53 is one of the first two central processing units implementing the ARMv8-A 64-bit instruction set designed by ARM Holdings' Cambridge design centre, along with the Cortex-A57. The Cortex-A53 is a 2-wide decode superscalar processor, capable of dual-issuing some instructions. It was announced October 30, 2012 and is marketed by ARM as either a stand-alone, more energy-efficient alternative to the more powerful Cortex-A57 microarchitecture, or to be used alongside a more powerful microarchitecture in a big.LITTLE configuration. It is available as an IP core to licensees, like other ARM intellectual property and processor designs.
This is a comparison of processors based on the ARM family of instruction sets designed by ARM Holdings and 3rd parties, sorted by version of the ARM instruction set, release and name.
Qualcomm Kryo is a series of custom or semi-custom ARM-based CPUs included in the Snapdragon line of SoCs.
The ARM Cortex-A73 is a central processing unit implementing the ARMv8-A 64-bit instruction set designed by ARM Holdings' Sophia design centre.
