Open Source Java Software Development Software

libjpeg-turbo is a JPEG image codec that uses SIMD instructions (MMX, SSE2, NEON, AltiVec) to accelerate baseline JPEG compression and decompression on x86, x86-64, ARM, and PowerPC systems. On such systems, libjpeg-turbo is generally 2-6x as fast as libjpeg, all else being equal. On other types of systems, libjpeg-turbo can still outperform libjpeg by a significant amount, by virtue of its highly-optimized Huffman coding routines. In many cases, the performance of libjpeg-turbo rivals that of proprietary high-speed JPEG codecs. libjpeg-turbo implements both the traditional libjpeg API as well as the less powerful but more straightforward TurboJPEG API. libjpeg-turbo also features colorspace extensions that allow it to compress from/decompress to 32-bit and big-endian pixel buffers (RGBX, XBGR, etc.), as well as a full-featured Java interface.

z390 Portable Mainframe Assembler and Emulator

This library allows developers to access native libraries (DLL and lib.so) from java. You do NOT need to compile a line of C/C++ to use it: it's dynamic !! Now Win32 DLL and shared libraries are usable with Java ;)

This project is for the portable computer "Cambridge Z88", produced by Sir Clive Sinclair (of ZX Spectrum fame). We continue to support software development (ROM, 3rd party apps on memory cards and desktop applications). We have moved to https://cambridgez88.jira.com/wiki (development, source code and documentation). However, we continue to publish files for download here.

Processor Expert components and Eclipse examples and plugins.

Jasmin is an interpreter for the x86 assembly language with a full-featured development environment aimed for educational purposes.

basE91 is an advanced method for encoding binary data as ASCII characters. It is similar to UUencode or base64, but is more efficient. The overhead produced by basE91 depends on the input data. It amounts at most to 23% and can range down to 14%.

SuperWaba is a Virtual Machine for handhelds. Runs in PalmOS, Windows CE, Win32, and is fully emulated under JDK/browser. Supports Exceptions, has a complete set of UI controls (Palm/WinCE), double and long, grayscale/color, sockets/serial/IR/Bluetooth

JBit is small java application for mobile phones (MIDlet) that gives you a programmable 8-bit microcomputer. With JBit, you can edit, save, run and debug assembly (6502) programs directly on your phone.

Vector Pascal is a language targeted at SIMD multi-core instruction-sets such as the AVX and SSE2 or x86-64-v3. It has a SIMD compiler which supports parallel vector operations, loop unrolling, common sub expression removal etc. It is implemented in Java.

A Java 2 (JDK 1.3/1.4) compatible virtual machine. joeq is unique in that it is almost entirely implemented in Java, making it reliable and efficient. It is also language-independent, so code from any language can be seamlessly and dynamically compiled.

ATmon is a bootloader and monitor tool for the Atmel ATmega32 microcontroller.

Compiler for java assembly to class file. This compiler contains dead code detection and allow creating method, field and constructor from a java assembly file

It moves by itself inside networks like virus infection & plagues, it is being written to solve computer virus problem drastically and responsibly. It is legal, free and open for public domain to improve W3 ICT Security.

ByteCode IDE is a C++ , Java, Python, Assembly, HTML, CSS development environment. Features : 1. Syntax Highlighting 2. Debugger 3. Sample Code Template 4. Runnable on both Linux & Windows 5. One Click Paste & Github push And many more....

This is a student project designed to compete in the 2010 IEEE Computer Society Student Competition: http://www.computer.org/portal/web/competition/2010competition The Code Red architecture is designed for extremely lower power environments, like distributed sensor networks. Included is a design of that architecture, a Java-based simulator, an implementation (without vector instructions) designed as a Logisim circuit (http://ozark.hendrix.edu/~burch/logisim/), and more. The name "Code Red" comes from our team name, the Red Team. Since the competition dictated a small team size, our professor split the class and gave each group a color. We liked the name "Code Red" and chose it to represent our team and school's color (UMass' official color is Maroon.) Only later did we realize that "Code Red" was the name of an unrelated computer worm from 2001.

Course Compiler Design I at the ETH Zuerich (Switzerland). The course program is to write a simple compiler for educational language J01 (similar to Java, with restrictions) for a target platform (either DLX, SPARC or x86).

This is meant to be a powerful, but easy to use math software. It's by the user and for the users.

A sub-C cross compiler for EduMIPS64 simulator. EduXcomp is a java project built using the antlr tool, and a grammar written by Monty Zukowski hardly modified by Elena Carobene, Massimo Trubia, and Alessio Tognazzolo.

FAIN SNAP provides an active network programming language and interpreter. It allows finite state machines to be operated over a number of network elements. Its main use is to program firewalls and raise alerts. It is a native Debian distribution.

This was originally an OSdev group, but since as members disbanded, I'm continuing to provide various implemenatitions of software, hardware, operating systems, libraries, and some stuff related to math and physics.
