Perhaps you should try the very similar, open, and proven b16 processor core? You could get eight into a X02-7000 FPGA for example, with about 3kB RAM each, and space left for some custom peripherals. (But nine cores might be better for symmetry) I've half finished a wrapper for the b16 which adds interprocessor links, and modified the core so that it can execute code and boot from an interprocessor link. If you really need the 18b data width, then we could also increase the number of instructions in each b16 fetch from three and a bit to three and a half. Would you like me to finish it, or would you be interested in taking over this project? Jan Coombs. -- email valid, else fix dots and hyphen jan4clf2014@murrayhyphenmicroftdotcodotuk
