A homebrew video suite for game consoles
A homebrew software suite for video game consoles developed to help in the evaluation of upscalers, upscan converters, line doublers and of course TV processing of 240p video. The Wii and Dreamcast versions have modes for 480i and 480p evaluation as well. It has tests designed with the processing of 240p signals in mind, although when possible it includes other video modes and specific tests for them. These have been tested with video processors on real hardware and a variety of displays, including CRTs and Arcade monitors via RGB. As a secondary target, the suite aims to provide tools for calibrating colors, black and white levels for specific console outputs and setups. Current platforms are: Sega Genesis (Mega Drive), Sega CD (Mega CD), PC Engine/Turbografx-16, Super CD-ROM2/CD-ROM2, NES/Famicom, Super Nintendo/Super Famicom, Sega Dreamcast, Nintendo Wii and GameCube.
ASAP (Another Slight Atari Player) plays and converts 8-bit Atari music (*.sap, *.cmc, *.mpt, *.rmt, *.tmc, ...) on modern computers and mobile devices.
Building and running ancient Linux on Windows
While I may have started with Linux 0.11, I've expanded this to include several older relases of the Linux kernel that you can cross compile from Windows, and run on Qemu. I've managed to get the older versions of the software tools running on Windows, so that there is no major invasive source changes, outside of either broken drivers, or massaging the makefiles to find things in the new paths, and calling the appropriate tools where needed. Linux 0.10 is the first oldest version of Linux that is somewhat usable. While it lacks things like TCP/IP, and robust filesystems, it does offer a small kernel size, perfect for playing around with. You can comfortably make changes on Windows, re-compile and test all from a 'normal' desktop.
FreeDOS is a free DOS-compatible operating system.
FreeDOS is a complete, free, DOS-compatible operating system that you can use to play classic DOS games, run legacy business software, or develop embedded systems. Any program that works on MS-DOS should also run on FreeDOS. It doesn’t cost anything to download and use FreeDOS. You can also share FreeDOS for others to enjoy! And you can view and edit our source code, because all FreeDOS programs are distributed under the GNU General Public License or a similar open source software license.

Realtime raytracer using SIMD on ARM, MIPS, PPC and x86
QuadRay engine is a realtime raytracing project aimed at full SIMD utilization on ARM, MIPS, Power and x86 architectures. The efficient use of SIMD is achieved by processing four rays at a time to match SIMD register width (hence the name). The rendering core of the engine is written on a unified SIMD assembler allowing single assembler code to be compatible with different processor architectures, thus reducing the need to maintain multiple parallel versions. At present, Intel SSE/SSE2/SSE4 and AVX/AVX2/AVX-512 (32/64-bit x86 ISAs), ARMv7 NEON/NEONv2, ARMv8 AArch32/AArch64 NEON (32/64-bit ARM ISAs), MIPS 32/64-bit r5/r6 MSA and Power 32/64-bit VMX/VSX (little/big-endian ISAs) are mostly implemented, although scalar improvements, horizontal reductions, wider SIMD vectors with zeroing/merging predicates in 3/4-operand instructions, are planned as extensions to current 2/3-operand SPMD-driven vertical SIMD ISA. See README file.
SIMD macro assembler unified for ARM, MIPS, PPC and x86
UniSIMD assembler is a high-level C/C++ macro assembler framework unified across ARM, MIPS, Power and x86 architectures. It establishes a subset of both BASE and SIMD instruction sets with clearly defined common API, so that application logic can be written and maintained in one place without code replication. The assembler itself isn't a separate tool, but rather a collection of C/C++ header files, which applications need to include directly in order to use. At present, Intel SSE/SSE2/SSE4 and AVX/AVX2/AVX-512 (32/64-bit x86 ISAs), ARMv7 NEON/NEONv2, ARMv8 AArch32/AArch64 NEON (32/64-bit ARM ISAs), MIPS 32/64-bit r5/r6 MSA and Power 32/64-bit VMX/VSX (little/big-endian ISAs) are mostly implemented, although scalar improvements, horizontal reductions, wider SIMD vectors with zeroing/merging predicates in 3/4-operand instructions, are planned as extensions to current 2/3-operand SPMD-driven vertical SIMD ISA. See README file.
Pattern-based multi/many-core parallel programming framework
FastFlow is a C/C++ programming framework supporting the development of pattern-based parallel programs on multi/many-core and distributed platforms. FastFlow run-time is built upon non-blocking threads and lock-free queues. Thanks to its very efficient CAS-free communication/synchronization support (e.g. few clock cycles core-to-core latency), FastFlow effectively supports the exploitation of fine grain parallelism, e.g. parallel codes managing very high frequency streams on commodity multi-core. FastFlow works on x86, x86_64, PPC, ARM, and Linux, Mac and Win XP/7. Latest version can be downloaded from the SVN using the following command: svn co https://svn.code.sf.net/p/mc-fastflow/code/ fastflow
