Yes, it's really not well thought through. Computational intensive tasks usually also are memory intensive. You need data to crunch? It's probably a lot of data then. Look at the competition. There's, on the one side: FPGAs. The Cyclone V 5CEA4 is a relatively low cost device, and has 144 18x19 multipliers (all single cycle, the GA144 multiplier are 1x18 multipliers, and AFAIK need two cycles per bit, because the carry propagation has to be taken into account - granted, the cycles are smaller, but propbably only by a factor of 3), 30 kB of on-chip memory (the GA144 has 18kB, and these 64 words per CPU are shared between program and data), 400MHz DDR2-RAM IOs to really have fast access to other memory, etc. Handling a GB Ethernet device in such a Cyclone 5 is not all that complicated - you need your external phy device. The other competition are GPGPUs. They have such an abundance of computation resources that they are rated in teraflops now (single precision). Chuck doesn't like the ultra-complex design software for current chips. He thinks his simplistic approach yields faster chips. I'm not convinced. I've done similar CPUs (b16) with similar technology, and ended up at comparable clock speeds, and I don't need to spend years tuning the thing for a particular technology - I can jump to the latest available or my sweet spot for affordability; even if I'm 30% slower than Chuck for a given technology, I can be 10 times faster by using the most recent technology, and pack 100 times as many cores on one die. If that would actually be a good idea. IMHO, Chuck is something like a one-man research institute. He has wonderful ideas, but it's research work, not actual product development. -- Bernd Paysan "If you want it done right, you have to do it yourself" http://bernd-paysan.de/
