A 16-bit single cycle stack processor based on Forth programming language is proposed in this paper

the processor has a data stack and a return stack of 32 elements deep

and a Harvard structure storage system.The instruction set of it includes 29 instructions

all of which could be completed within single cycle.When implemented on Xilinxs XC5VLX110T FPGA

The processor could run up to 162.7M Hz.The paper first introduces the design principle

architecture and instruction set of the processor and then analyses the strategy of instruction single cycle execution.Finally

it presents the result of hardware synthesizing and software simulation and analysis of it.
