1: This directory contains assembler and primitives for the 4stack
2: processor. Create an gforth image for the misc simulator with
3:
4: make kernl-4stack.fi
5:
6: This also creates the file gforth.4o for the simulator in the directory
7: ../4stack.
8:
9: Load this image into the simulator and run the simulator with
10:
11: cd ../4stack; 4stack gforth.4o
12:
13: Additonally, there are two more complex examples (two terminal games,
14: Sokoban and Tetris). To create the image, do the following:
15:
16: Add
17:
18: include arch/misc/sokoban.fs
19: include arch/misc/tt.fs
20:
21: in main.fs just before "include special.fs". Perform a make
22: kernl-4stack.fi like above. Move the resulting gforth.4o to
23: gforth-games.4o, and start the simulator:
24:
25: cd ../4stack
26: mv gforth.4o gforth-games.4o
27: 4stack gforth-games.4o
28:
29: Now type in "sokoban" <return> or "tt" <return> to play sokoban or
30: tetris (both run at reasonable speed on a Pentium 133). To stop either
31: game, type "q".
32:
33: More informations about the 4stack processor, including a description
34: of the architecture, a user manual, a simulator, and a description of
35: a sample implementation in Verilog can be found in
