碩士 === 中華大學 === 電機工程學系碩士班 === 88 === Forth is a language that was invented by Dr. Charles Moore in 1979 for direct communication between human beings and machines. Less than 16K byte memory Forth OS can provide both interpreter and compiler. Forth may allow user to access the lowest level of hardware resources as well as supports high level of instructions. The compiler poses the ability to extend the language itself where this feature seldom appears in the other one. In this paper we discuss how to fit a Forth Engine (CPU) into design. It begins to define the instruction set by extracting eForth primitive command. Step by step creation of Forth Engine hardware architecture is introduced. This architecture is easy to be implemented by VHDL language and to be realized by using FPGA. Finally we will explain the format of the Forth Engine OS binary code, which is translated from a PC program, for installing into the FPGA’s configuration and cell array memory. This paper can also be as a reference for Forth user to be used in research.
