Huh? If I'm not mistaken, Ambit is not a new development. I remember reading about it. (or at least some other commodity DRAM bitwise accelerator)

- puzzle 9y agoTwenty years ago, Sun had special RAM in their Elite3D cards to do write-only alpha blending and z-buffering (saturated updates), instead of the much slower read-modify-write: one PCI write instead of one read + CPU computation + one write. That might have been UPA or even Sbus instead of PCI, but you get the idea. ATI and E&S later used it, too. http://www.michaelfrankdeering.com/Projects/HardWare/p3DRAM/p3DRAM.html http://www.michaelfrankdeering.com/Projects/HardWare/p3DRAM/... This looks like a variant of the Sun/Mitsubishi work, after a quick skim.
