  • 32 KiB data
L2 cache 256 KiB–8 MiB (configurable with L2 cache controller)

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.[1] 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.[2][3]

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):
