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-bitARM architectureCPU development on which hundreds of engineers had already worked for three and half years and which also has 32-bitARM architecture backward compatibility. Project was started in Stexar company (Colorado) as x86-compatible processor using binary translation like in Transmeta's projects. Stexar was acquired by Nvidia in 2006.
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 Denver-based Tegra chip (codenamed Parker, probably Tegra 6) is expected to be released in 2015 or in 2014.
A Denver-based CPU will be integrated into an SoC with a GPU core based on Nvidia's upcoming architecture (codenamed Maxwell).
