Simplify virtually executes an app to understand its behavior and then tries to optimize the code so that it behaves identically but is easier for a human to understand. Each optimization type is simple and generic, so it doesn't matter what specific type of obfuscation is used. Provides a virtual machine sandbox for executing Dalvik methods. After executing a method, it returns a graph containing all possible register and class values for every execution path. It works even if some values are unknown, such as file and network I/O. For example, any if or switch conditional with an unknown value results in both branches being taken. Analyzes the execution graphs from smalivm and applies optimizations such as constant propagation, dead code removal, unreflection, and some peephole optimizations. These are fairly simple, but when applied together repeatedly, they'll decrypt strings, remove reflection, and greatly simplify code. It does not rename methods and classes.

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.

z390 Portable Mainframe Assembler and Emulator

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.

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 aims to implement an LC2/LC3 assembler and simulator for the Linux and Windows platforms.

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.

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.

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.

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.

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.

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

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 Java based simulator for the LC-3 16bit processor used in several CSS classes. (specifically in the book "Introduction to Computing Systems: From Bits and Gates to C and Beyond" (2nd Ed) Moved to GitHub

MEM Net - Mote EMulator Network. This project will focus on: 1) MEM - Wireless Sensor Node (mote) emulator 2) MEM Net - network of emulated motes So far, the only released package is “visual-sim-slides”. More comming next !

Mahatma68k is a free/Open Source emulator library for the legendary Motorola 68000 CPU written for the Java virtual machine.

Mesya is a Java framework for multiple entertainment systems emulation

Ellipsis is a modular, agent-oriented, and extendable toolkit to execute stationary and mobile software agents written in the Java programming language. Ellipsis uses the standard application server JBoss (version 4.2.3 GA) without any modifications. In contrast to existing mobile agent toolkits, Ellipsis has an agent- and message-oriented architecture. Ellipsis is built on top of the JMX architecture. Core Ellipsis components are implemented as MBeans which provides for basic ser-vices to execute agents and control their life-cycle. One of the core components is a special MBean (AgentModul) that makes it possible to load an agent powered by agent engines. Agent engines can execute one type of agent. Based on this mechanism, agents can be added dynamically to a running system, can be stopped (for example in case of an error) and restarted later. Ellipsis already comes with a predefined set of agents, offering basic services like agency, loader, holdingarea and migration.
