Ultra Technology Inc. has licensed the F21 design from Charles Moore's company Computer Cowboys. F21 contains a Forth Engine CPU and coprocessors for multimedia, parallel processing, and artificial intelligence applications.
F*F is a parallel processing extension for F21 ANS Forth compilers. F*F provides support for symetric multiprocessing using the on chip network interface on the F21 chip. Easier than OCCAM or Linda, F*F provides a very simple but powerful scalable multiprocessing environment where parallel execution is dynamically ballanced at runtime.
