Alpaca is a multitasking operating system for Z-80 based arcade hardware. It has been designed to run on both Pac-Man and Pengo based arcade machines, but can easily be ported to other machines with similar architectures. It supports four concurrently running processes, task switching, simple inter-process messaging, semaphores, and a basic window-based graphical interface.
The Torque Network Library is a robust, secure, and easy-to-use cross-platform C++ networking API designed for high performance simulations and games. It features a UDP- based connection architecture with DoS prevention functionality, different types of data guarantee, bit stream compression, server object replication and updating, and a simple, highly space efficient RPC mechanism. It includes a deterministic application journaling replay function for eliminating hard to find networking bugs.
Java Grinder takes Java byte-code from a class file and compiles it into an assembly code text file that can be assembled and run on microcontrollers and CPUs including MSP430, dsPIC, 6502 (Commodore 64), 68000, ARM, and MIPS. A Java API is provided for dealing with SPI, GPIO, Commodore 64 hardware, and more.
cpuinfo consists of an API/library used by programs to get information about the underlying CPU. Such information includes CPU vendor, model name, cache hierarchy, and supported features (e.g. CMP, SMT, and SIMD). cpuinfo is also a standalone program to demonstrate the use of this API.
