The ARM Cortex-A17 is a 32-bit processor core implementing the ARMv7-A architecture, licensed by ARM Holdings. Providing up to four cache-coherent cores, it serves as the successor to the Cortex-A9 and replaces the previous ARM Cortex-A12 specifications. ARM claims that the Cortex-A17 core is 60% more powerful than the Cortex-A9 core, providing 3.3 DMIPS/MHz/core vs. 2.5 DMIPS/MHz/core.
ARM renamed A12 to a variant of Cortex-A17 since second revision of the core in early 2014, because they were indistinguishable in performance and all features of the A17 were used to upgrade A12.
New features not found in the Cortex-A9 are all from the third-generation ARM Cortex-A (including Cortex-A7 and Cortex-A15 as well):
- Hardware virtualization and 40-bit Large Physical Address Extensions (LPAE) addressing
- Support of big.LITTLE architecture
- Floating point and SIMD unit NEON, VFPv4 replaces VFP3
- 10-12 stage integer pipeline
- Full out-of-order execution design with load/store units
