Google confirmed the deal but declined to disclose financial terms. The acquisition was first reported Tuesday by The Register and The Wall Street Journal.
Newer computers contain advanced processors, but it's often a challenge to write software that can unlock that power.
Software is most often designed to run in a linear fashion on a single processing core, but multicore chips can handle two or more tasks simultaneously. At the same time, graphics chips are increasingly suited not just for drawing elaborate videogame scenes or architectural renderings, but also general-purpose programming as well.
And ordinary computers can be spruced up with gaming chips such as the. Such programming tasks are difficult; to try to make programming Cell easier, for example.
Google's interest in such technology is logical. The company runs thousands of servers and is concerned about getting the maximum use out of each one., for example. Google also employs numerous programmers who have an interest in such matters as the compilers that convert the source code written by humans into the binary instructions a computer understands.
PeakStream Chief Executive Neil Knox formerly ran Sun Microsystems' x86 and low-end Sparc server business.
Like Google and Sun, PeakStream also has Stanford University roots. Its software began as the Brook Project at Stanford by professor Pat Hanrahan, the company's co-founder and chief scientist. The other company co-founder is Chief Technology Officer Matt Papakipos, who was lead architect for Nvidia's GeForce 6 series of graphics chips, also known as the NV4X products. Varun Mehta, formerly of Network Appliance, is vice president of engineering.
