While Intel’s platform engineers devised more and more creative ways to improve multiprocessor performance using the front-side bus, a highly scalable next generation interconnect was being jointly designed by engineers from teams across Intel and some of the former Alpha designers acquired from Compaq. This new interconnect, known internally as the Common System Interface (CSI), is explicitly designed to accommodate integrated memory controllers and distributed shared memory. CSI will be used as the internal fabric for almost all future Intel systems starting with Tukwila, an Itanium processor and Nehalem, an enhanced derivative of the Core microarchitecture, slated for 2008. Not only will CSI be the cache coherent fabric between processors, but versions will be used to connect I/O chips and other devices in Intel based systems..Check it out over here.
