Project Denver is the codename of a CPU/GPU-microarchitecture designed by Nvidia and based on the ARM instruction set. Project Denver is targeted at personal computers, servers, and supercomputers. The CPU package will include an Nvidia GPU on-chip.
The existence of Project Denver was revealed at the 2011 Consumer Electronics Show. In a March 4, 2011 Q&A article CEO Jen-Hsun Huang revealed that Project Denver is a five year 64-bit ARM architecture CPU development on which hundreds of engineers had already worked for three and half years and which also has 32-bit ARM architecture backward compatibility. Project Denver was started in Stexar company (Colorado) as an x86-compatible processor using binary translation like in Transmeta's projects. Stexar was acquired by Nvidia in 2006.
According to Tom's Hardware, there are engineers from Intel, AMD, HP, Sun and Transmeta on the Denver team, and they have extensive experience in designing superscalar CPUs with out-of-order execution, very long instruction words (VLIW) and simultaneous multithreading (SMT).
According to Charlie Demerjian, the Project Denver CPU may internally translate the ARM instructions to an internal instruction set, using firmware in the CPU. Also according to Demerjian, Project Denver was originally intended to support both ARM and x86 code using code morphing technology from Transmeta, but was changed to the ARMv8-A 64-bit instruction set because Nvidia could not obtain a license to Intel's patents.
A dual-core Denver-based Tegra chip, 64-bit variant of SoCs from Tegra K1 family, is expected to be released in the second half of 2014 It will be able to execute 64-bit ARMv8 code. Each CPU will be 7-way superscalar with 128 KiB + 64 KiB of L1 cache and running at up to 2.5 GHz.
A Denver-based CPU will be integrated into an SoC with a GPU core based on Nvidia's upcoming architecture (codenamed Maxwell).
