How to compile Haskell to Reduceron code? I don't know answers to most of your questions. But colleague of mine said that reduceron could be programmed into FPGA part of upcoming Atom E600 - the one with Altera FPGA nearby. ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
[Haskell-cafe] Reduceron: reduced to numbers.
I decided to calculate Reduceron's number of transistors (I had to, we have some argument here;). Reduceron allocate 14% of 17300 slices of Virtex-5 FPGA. If we assume that each slice correspond to 8 4-input NAND-NOT elements, we will get 2 4-input NAND. Each 4-input NAND contains 8 transistors, so the count of logic transistors is about 16. Reduceron use 90% of 1.5Kbyte RAM blocks. Using 6 transistors per RAM bit, we get 66K transistors more. So Reduceron should contain about 230K transistors if someone decides to go ASIC. It's 3 orders of magnitude less than x86, on par with most late chips of Chuck Moore (inventor of Forth, MISC concept and the one who develops some strange chips in GreenArrays http://greenarraychips.com/ now). The difference between Reduceron and GA144 of Chuck Moore is that Reduceron could be programmed much more easily, and that rocks. Clock frequency of 96MHz should go up too. My experience suggest numbers between 5 and 8 times. So single Reduceron should be of equal performance to Core2 Duo, at least. PS Of course, Reduceron in ASIC will require some cache memory, some controllers, etc. So it won't be that small, like 230K transistors. But, mzke it 2.3M transistors and it still be 2 orders of magnitude less than Core2 Duo... ;) ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
