EP32 - a 32-bit Foth Micorprocessor
Edvin Hjrtland, Li Chen · 2007
This paper introduces a design of a 32-bit Forth microprocessor - EP32. It is a stack based processor, well suited for the Forth programming language. The instruction set includes 35 RISC-like instructions. The EP32 processor has two stacks: the data stack and the return stack which are 256 levels deep. The 32-bit Forth processor is designed in VHDL, and synthesized with a 0.18 mum standard CMOS library. The processor will be synthesized with a radiation-hard-by-design digital library in the future for space applications.
