Engineer Implements Reversible 1D Cellular Automata Using Bitwise Operations
2024-12-12
Richard Palethorpe, an engineer, created a demo using the GFXPrim library showcasing a one-dimensional binary cellular automaton and its reversible counterpart. The automaton evolves based on rules where each cell's state is determined by its own state and those of its left and right neighbors. The article details bitwise operation optimizations, such as parallel processing of multiple cells using 64-bit integers and bit rotation to simulate neighbor interaction. Reversible implementation is achieved by XORing with the previous state. The author explores compiler optimization and vectorization impacts on performance and ultimately implements an efficient rendering method.
