JFAR: Journal of Forth Application and Research: v5
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.

Overview of the E16 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.

New Micros, Inc.
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. Since 1980.

4stack Processor
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 processor, with no further RISC core.

Enumera, Inc.
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.
