This directory contains assembler and primitives for the 4stack
processor. Create an gforth image for the misc simulator with
make kernl-4stack.fi
This also creates a file for the simulator in the directory ../4stack.
Load this image into the simulator and run the simulator with
cd ../4stack; 4stack kernl-4stack.4o
Additonally, there are two more complex examples (two terminal games,
Sokoban and Tetris). To create the image games-misc.fi, do the
following:
Add
include arch/misc/sokoban.fs
include arch/misc/tt.fs
in main.fs just before "include special.fs". Perform a make
kernl-4stack.fi like above. Move the resulting kernl-4stack.4o to
games-4stack.4o, and start the simulator:
cd ../4stack
mv kernl-4stack.4o games-4stack.4o
4stack games-4stack.4o
Now type in "sokoban" <return> or "tt" <return> to play sokoban or
tetris (both run at reasonable speed on a Pentium 133). To stop either
game, type "q".
More informations about the 4stack processor, including a description
of the architecture, a user manual, a simulator, and a description of
a sample implementation in Verilog can be found in
