DirectX 11 is a set of APIs (application programming interfaces) that are capable of bringing more realistic images to Microsoft's Windows 7 OS, which is used on PCs. But Windows 7 works on Intel processors and does not work with Arm processors, while Microsoft's smartphone OS -- Windows Phone 7 -- does not include full DirectX 11 compatibility. Arm's Smythe declined to comment whether Microsoft's smartphone OS would eventually build in full DirectX 11 capabilities.
The company is providing support for the DirectX 11 framework in case Arm licensees need it, Smythe said.
"We really can't comment on Microsoft's roadmap," Smythe said. "We see it as a requirement from our semiconductor customers to have the capability to support DX."
Microsoft did not immediately respond to request for comment.
The OpenCL standard includes a C-like programming language with APIs to enable parallel task execution. IBM, Apple, Intel, Nvidia and Advanced Micro Devices are among the backers of OpenCL.
