8-bit programmable computer is an implementation of an 8-bit computer in Conway's Game of Life designed and built in 2016 by Nicolas Loizeau.[1]
An improved version of the design with optimized circuitry, a 32x32 display, and instructions to handle arrays was created in 2021.[2]
Architecture
The computer supports eight variables and 13 instructions -- write, goto, move, jumpif, print, add, or, and, xor, not, flat, sign, and increment. The computer is programmed by changing the arrangement of structures in its Program area.
The improved version possesses two more instructions, shift and rotate.
Comparison with other computer patterns
- The 8-bit programmable computer is considerably simpler than the Spartan universal computer-constructor, in large part because it does not contain a universal-construction component.
- It is easy to program with the help of the associated Python utility script, assembly.py, and associated resources which can be found in the project's GitHub repository.[3][4]
- It is capable of performing standard 8-bit AND, OR, XOR, and NOT operations using any of its eight variables. The improved version can process up to 128 variables, each of which can be 8-bit, 16-bit, or 32-bit. Additionally, the improved version can use its variables as addresses that can be read from or written to.
