Intel Programmable Systems Group takes step towards FPGA based system in package

I'm a newbie so pls excuse my ignorance .. Cypress has these had these things for a bit .. they call them PSOC. Basically, an ARM core plus some programmable logic. Is the difference here that the processor and PLD are both beefier? I'm generally confused about the difference between PLD vs FPGA vs CPLD. It seems there is no precise definition and it changes based on who is talking.

Hmm this made me wonder: what would happen if you made a system that supported multiple architectures (ARC, PPC, x86, FPGA, ...) at the same time ?

This can be a real breakthrough in computing technology. Just in time, as the improvement of desktop and server CPUs has stalled almost completely.

Site seems down. I tried to find an alternative source but didn't come up with much.
