Cortex-A15
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. Overview ARM has claimed that the Cortex-A15 core is 40 percent more powerful than the Cortex-A9 core with the same number of cores at the same speed. The first A15 designs came out in the autumn of 2011, but products based on the chip did not reach the market until 2012. Key features of the Cortex-A15 core are: * 40-bit Large Physical Address Extensions (LPAE) addressing up to 1 TB of RAM. As per the x86 Physical Address Extension, virtual address space remains 32 bit. * 15 stage integer/17–25 stage floating point pipeline, with out-of-order speculative issue 3-way superscalar execution pipeline * 4 cores per cluster, up to 2 clusters per chip with CoreLink 400 (CCI-400, an AMBA-4 coherent interconnect) and 4 clusters per chip with CCN-504.

Exynos
Exynos, formerly Hummingbird (), 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. Exynos is mostly based on the ARM Cortex cores with the exception of some high end SoCs which featured Samsung's proprietary "M" series core design; though from 2021 onwards even the flagship high-end SoC's will be featuring ARM Cortex cores. History In 2010, Samsung launched the Hummingbird S5PC110 (now Exynos 3 Single) in its Samsung Galaxy S smartphone, which featured a licensed ARM Cortex-A8 CPU. This ARM Cortex-A8 was code-named Hummingbird. It was developed in partnership with Intrinsity using their FastCore and Fast14 technology. In early 2011, Samsung first launched the Exynos 4210 SoC in its Samsung Galaxy S II mobile smartphone. The driver code for the Exynos 4210 was made available in the Linux kernel and support was ...
