Project Denver SoC will be the first 64-bit ARM processor for Android

NVIDIA Tegra K1 versions

NVIDIA has revealed architectural details of the 64-bit version of the Tegra K1 System-on-Chip (SoC). Being developed under the Project Denver code name, it will be the first 64-bit ARM SoC for Android.

The 32-bit version of Tegra K1 already powers several notable mobile devices, including the NVIDIA Shield tablet and the just announced Acer Chromebook 13.

From the official announcement:

This new version of Tegra K1 pairs our 192-core Kepler architecture-based GPU with our own custom-designed, 64-bit, dual-core “Project Denver” CPU, which is fully ARMv8 architecture compatible. Further, Denver is fully pin compatible with the 32-bit Tegra K1 for ease of implementation and faster time to market

Denver is designed for the highest single-core CPU throughput, and also delivers industry-leading dual-core performance. Each of the two Denver cores implements a 7-way superscalar microarchitecture (up to 7 concurrent micro-ops can be executed per clock), and includes a 128KB 4-way L1 instruction cache, a 64KB 4-way L1 data cache, and a 2MB 16-way L2 cache, which services both cores.

Denver implements an innovative process called Dynamic Code Optimization, which optimizes frequently used software routines at runtime into dense, highly tuned microcode-equivalent routines. These are stored in a dedicated, 128MB main-memory-based optimization cache. After being read into the instruction cache, the optimized micro-ops are executed, re-fetched and executed from the instruction cache as long as needed and capacity allows.

Devices powered by the 64-bit version of Tegra K1 should be on the market later this year. For more on what this means for those devices, read the official design and performance description here.
