• - Goal: dominate very low cost, low power, single core CPU market, and have the only ultra-high-end supercomputer on-a-chip system. Because the CPU core is so small, it is possible to put 1000s of cores and memory in one IC chip package.
  
• - Research project for high performance, low cost computing. Uses stack based instructions for a 4-way VLIW processor. Implemented in current technology, it would outrun high-end DSPs (TMS 320C6x, TigerSHARC), and let the full application run on one process
  
• - Philip J. Koopman, Jr., CMU page. Many reports, studies, links. Compares: CISC, RISC, Stack systems; 2 & 3 stack systems. Excellent resource.
  
• - Course on minimal processors: Guided Exploration of two FPGA-based CPU Designs, led by John Rible.
  
• - JOP is the implementation of a small java processor with the JVM fitting in a FPGA.
  
• - Small, powerful Forth embedded computers: let you quickly design applications: controls, portable instruments, terminals, data loggers, GPS, CAN bus, multitasking, LCD and keyboard systems. High level language makes development simple and fast; needs no P
  
• - Makes IGNITE I ROSC (Removed Operand Set Computer), PSC1000 32-bit embedded shBoom-based microprocessor line, many ISDN interface products, sophisticated antenna/radar technologies.
  
• - Designs, builds: single board computers (SBC), peripherals, embedded systems, PCB design/layout, high level programming (industry leaders in Forth), custom design work; large line of stock products: from full handheld computers to development packages. Si
  
• - Minimal instruction set, small, low power 16-bit CPU optimized to run Forth on a Xilinx FPGA. When system is stable, VHDL source code for CPU and all other code will be released to make a full open source public domain CPU.
  
• - Small, fast stack-based processor for FPGAs. CPU prototyped and debugged in ANS Forth. A simple RTL-specific language extension provides discrete event simulation for structural model of CPU and allows concise architecture representation.
  
• - 1987 Rochester Forth Conference Proceedings. Four abstracts of Forth processor systems. This was the same conference at which the S.N. Baranoff papers were first publicized in the West.
  
• - References, links to Forth and stack machines in various technologies.
  
• - Free on-line book by Philip J. Koopman, Jr. Read it on-line, or download it in several formats including 700k zip file. Published in 1989, the first book to explore a new breed of stack computers led by introduction of Novix NC4016.
  
• - Stack-based processors, 5-bit words, 25 instructions, 7000 transistors, 80 MIPS, 50 milliwatts, low cost; designed by Chuck Moore, creator of Forth programming language.
  
• - Uses of Forth microprocessors and programming language: controllers for spacecraft flight systems, on-board payload experiments, ground support; hardware or software to build or test flight or ground systems.
  
• - Embedded systems consultant for small (8/16-bit) and distributed microprocessor systems. Contract hardware and software development for most microcontrollers. Specialist: Forth, Assembly, C. By Bradford J. Rodriguez, Ph.D.
