@tb100: "You would almost think that Intel was up to something!"
Very impressive!! You really manage to stay on top of things!!
But I would add one more deal: Intel funded Silistix, a Manchester Unversity start-up leaded by Steve Furber (one of the original ARM architects) and which focused in the development of an asynchronous On-Chip core interconnect.
You can find more info in the next Silistix Limited website -- where references to Intel has been convenently suppressed, of course ;-)
Intel has been involved with a number of asynchronous logic companies. They bought Fulcrum, which has a number of chips, including Ethernet switches, that use asynchronous logic inside. And they partner with Achronix, which makes FPGAs that utilize asynchronous techniques for internal data pipelining.
You would almost think that Intel was up to something!
Clock gating is also supported in most of the clock buffers in Xilinx 7 Series devices, e.g. in global clock buffers (BUFG) and horizontal clock buffers -- a regional clock distribution network -- (BUFH).
You can also select a lot of different clock inputs for each different clock distribution network, including internally generated clocks.
Ther is more info about this in the next user guide:
@Max: "I remember a time when I thought Sun Microsystems would be around for ever ... it's like the old saying goes: "The bigger they are, the harder they fall" -- it was a sad day when they disappeared :-("
Yes, a very sad day. I really loved SUN Microsystem: its technology, both hardware and software, its openness, its advanced research... Some people think that they were too smart, commited and professional for staying alive in these weird days we are living now.
Max, what a cool collection of 3D ICs related blogs. They suppose a pretty nice reading before going to sleep for me now ;-)
By the way, back in 2007, I was trying to launch a project with a big company in order to build a new asynchronous 3D FPGA architecture. The project was really interesting and very smart planned. Unfortunately, those were bad times for the company, and there were rumours about IBM going to buy it -- finally, Oracle was the one which absorbed the company I was dealing with: SUN Microsystems :-(
