Analysis of program support at the level of Chip-Abstraction-Layer firmware and drivers SoC Samsung Exynos 5433 on 64-bit cores from ARM showed that core ARM Cortex A57 and A53 work in 32-bit mode. Yes, they support improved 32-bit instructions set out AArch32, but the regime AArch64 seems not available for them.
Support for this 64-bit is expected with the arrival of the seventh generation SoC company Samsung - it will probably chip Exynos 7420. This 20-nm processor at this stage may be one of the most interesting and innovative solutions. The performance of the Exynos 5433 can yield only NVIDIA Tegra K1, and devices of it has already begun to appear. For example, the smartphone Galaxy Note 4 , has claimed to supply in some regions of the world. A similar solution in the face of Qualcomm SoC Snapdragon 810 will be released only after six months.
Add officially specification SoC Exynos 5433 is not yet published. From what is expected, it is known that it is a combination of four big.LITTLE 1.3 GHz Cortex A53 cores and four 1.9 GHz cores Cortex A57. The graphics core solutions - is Mali T760MPh with a frequency of 700 MHz. Dual-channel memory controller with 32-bit capacity of up to 13.2 Gbit / s.
