Rambus In Cell

Rambus just proudly announced that their XDR memory interface would be used in the elusive Cell processor, being announced today at the International Solid State Circuits Society conference (ISSCC) in San Francisco.
There's not much surprise that Rambus was selected to be involved with the Cell project, given their previous history with Sony and the Playstation 2, as well as their ability to deliver extremely high bandwidth memory devices on very low pincounts. Sony and Toshiba also signed a licensing agreement back at the start of 2003 to work on the Cell project.

For years Rambus has been telling us that they've been working with GPU manufacturers on getting their high-bandwidth designs into future GPU architectures, and their design win with Sony may just be the key to getting XDR on PC graphics cards as well - especially since NVIDIA handled GPU design for the Playstation 3.

The other interesting part of Rambus' announcement is that they are also responsible for the Cell processor interfaces - it's connection to the outside world (or to other Cell processors). Rambus has had a serial processor bus interface in their IP repertoire for quite some time now, called FlexIO. FlexIO is being used as the processor interface standard for Cell.

    bout time they announced that... IBM/Sony have been saying that for quite a while (their patents have been anyways)

    XDR isn't used for the GPU on the PS3 though, it's attached to the Cells (high speed superscalar vector processors).

    ...as stated above in the summary, like i said
