CPU Sim is a software development environment for the simulation of simple computers. It was developed by Dale Skrien to help students understand computer architectures . With this application the user is able to simulate new or existing simple CPUs.
Free and open-source software portal; The gem5 simulator is an open source discrete-event computer architecture simulator. [1] It combines system-level and microarchitectural simulation, allowing users to analyze and test a multiplicity of hardware configurations, architectures, and software environments, without access or development of any hardware.
Simics is a full-system simulator or virtual platform used to run unchanged production binaries of the target hardware. Simics was originally developed by the Swedish Institute of Computer Science (SICS), and then spun off to Virtutech for commercial development in 1998.
a CPU emulator or CPU simulator (the two terms are mostly interchangeable in this case), unless the target being emulated has the same CPU architecture as the host, in which case a virtual machine layer may be used instead; a memory subsystem module; various input/output (I/O) device emulators
VisSim - system simulation and optional C-code generation of electrical, process, control, bio-medical, mechanical and UML State chart systems. Vortex (software) - a complete simulation platform featuring a realtime physics engine for rigid body dynamics, an image generator, desktop tools (Editor and Player) and more. Also available as Vortex ...
ARMulator - CPU simulators for the ARM architecture, provided by ARM itself as both a reference and software development vehicle. Computer architecture simulator; CPU Sim - Java-based program that allows the user to design and create an instruction set and then run programs of instructions from the set through simulation
There is a freely available MIPS32 simulator (earlier versions simulated only the R2000/R3000) called SPIM for use in education. EduMIPS64 [50] is a GPL graphical cross-platform MIPS64 CPU simulator, written in Java/Swing. It supports a wide subset of the MIPS64 ISA and allows the user to graphically see what happens in the pipeline when an ...
A cycle-accurate simulator is a computer program that simulates a microarchitecture on a cycle-by-cycle basis. In contrast an instruction set simulator simulates an instruction set architecture usually faster but not cycle-accurate to a specific implementation of this architecture; they are often used when emulating older hardware, where time precision is important for legacy reasons.
