The fast x86 PC emulator in 100% pure Java

Rifidi is a middleware and development platform for RFID. With Rifidi you can prototype an RFID application down to the core RFID Hardware and using Rifidi Edge you can easily develop business rules to turn RFID events into real business applications.

BT-Sim is a BlueTooth simulator on a HCI level. The project alows to develop and test BT applications without using real BT hardware. It works in particular with PalmSource's Palm OS Simulator.

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.

GNUDE is a complete suite of GNU C, C++, Fortran, and Java Cross Compilers, and the GDB CPU Simulator and Debugger for embedded microprocessor applications development. Targets development for ARM7, ARM9, and XScale applications.

Emulator of the ancient 8 bit microprocessor ISP-8A 500D/600D or more common "SC/MP" from National Semiconductor. The download contains all sources plus an executable Java Jar file to start right away. Some SC/MP hex dump examples are provided in directory "/etc" as well. The download also contains unit tests and some helping documentation (also in /etc). You may slow down the CPU operations, displaying the CPUs status register as LEDs, to watch the CPU working with its registers. The emulator also contains a VDU (video display unit) output / ASCII input simulation. There are some demos in /etc. And have a look to the NIBL / TINY BASIC interpreter in the TINYBASIC folder, most of the code is over 40 years old. Have fun, Theo Heinrichs

AdaptiveCells J2EE generates test-beds for benchmarking J2EE performance. They consists of highly customizable EJB cells that can emulate CPU load, memory usage, memory leaks and exceptions. The behaviour of the cells is coordinated from a web front-end.

A Java emulator for 80x86

Alchemy OS is a software development and distribution platform for mobile phones with Java support. Although this is not an operating system in the full sense, it provides rich platform to develop, compile and run applications directly in the phone, as well as install already written applications.

Avrora is a suite of tools for analyzing and debugging programs for AVR microcontrollers. It has support for a sensor platforms such as Mica2 and MicaZ, allowing wireless network simulation and allows dynamic instrumentation and static analysis.

Blubber system is an Eclipse RCP application for distributed systems modeling. Designed for university researches and inlcudes: task graph editor; graph transformation tools; graph modelling on distributed system; real-time modelling on GerdaFramework.

Castadiva is a test bed based on low-cost off-the-shelf devices, which is used to test protocols developed for MANETs. Castadiva is completely compatible with the file format used by the ns-2 simulator.

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.

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

Emutils are a collection of utilities for dealing with files which are in formats most commonly used by Commodore 64 emulators (D64, D71, D81, etc). These include search tools, extractors, converters, archive tools, etc. especially for batch operations.

It is a lejos emulator for the lego RCX. It can be used to test your code without having to go through the painful process of continuously uploading the code to the RCX. It does this by providing a emulation of the major parts of the lejos library.

Java Runtime Environment (JRE) 1.4.1 implementation for the Amiga Platform (OS 3.9 & 4.0)

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.

An Open Source Java Emulation platform for emulating micro computers

The Java Framework for Computer Emulation (JFraCE) is a framework written completely in Java for emulating (old) computer systems on the software level. Currently only an emulator of a Z80-based CP/M machine is implemented.

JSim8086 is platform-independent Assembly Language Simulator of the Intel 8086 CPU. It was designed to be a learning tool (CAL) for first year Computing students who are learning Computer Systems Organisation and Assembly Programming.

A bridge to the Java virtual machine via JNI for Haskell (and perhaps later other functional lanaguages).
