A Cornell ECE4760 course project demonstrates that the RP2040 microcontroller's DMA subsystem is Turing complete, building a functional fetch-execute CPU entirely out of DMA channel operations without involving the ARM cores.
An in-depth technical blog post explaining how to efficiently transpose matrices using SIMD instructions on modern x86_64 CPUs, focusing on AVX2 intrinsics like _mm256_shuffle_epi8.
A detailed write-up of a 16-byte x86 real-mode DOS demo that generates an infinite Sierpinski fractal in video memory while simultaneously producing audio output, showcasing extreme algorithmic density in the demoscene tradition.
A tutorial guide that walks through setting up a Rust project to build a ROM that runs on the Game Boy Advance, covering project setup and pixel rendering.
The author details the third iteration of the bx library's cross-platform SIMD abstraction, advocating for a typeless approach and SSA-style coding to simplify low-level performance optimization across different CPU architectures.
The article discusses the complexities of VGA memory access and the challenges of emulating old hardware due to inadequate documentation.
