List of emulators

List of emulators is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand List of emulators rather than just read about it. In short: This article lists software emulators. Central processing units ARM ARMulator Aemulor QEMU MIPS SPIM: The OVPsim 500 mips MIPS32 emulator, can be used to develop software using virtual platforms, emulators including MIPS processors running at up to 500 MIPS, the processor is capable of running many OSes including Linux.

Key takeaways

List of emulators belongs to computer science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect List of emulators to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of List of emulators from memory before moving on to harder problems.

Reference excerpt

This article lists software emulators.

Central processing units

ARM ARMulator Aemulor QEMU

MIPS SPIM: The OVPsim 500 mips MIPS32 emulator, can be used to develop software using virtual platforms, emulators including MIPS processors running at up to 500 MIPS, the processor is capable of running many OSes including Linux. OVP is used to build emulators of single MIPS processors or multiple - homogeneous MP or heterogenous MP.

Multi-system emulators blueMSX: Emulates Z80 based computers and consoles MAME: Emulates multiple arcade machines, video game consoles and computers DAPHNE is an arcade emulator application that emulates a variety of laserdisc video games with the intent of preserving these games and making the play experience as faithful to the originals as possible. The developer calls DAPHNE the "First Ever Multiple Arcade Laserdisc Emulator" ("FEMALE"). It derives its name from Princess Daphne, the heroine of Dragon's Lair. HYPSEUS is a modern SDL2 update to the DAPHNE emulator, named after a sibling to Daphne.

Operating system emulators

Unix Cygwin: For Microsoft Windows, provides a POSIX environment and system libraries (contained in cygwin.dll). This does not allow running unaltered Unix or Linux binary files (binaries). However, it allows use of the GNU compiler collection (gcc) to compile software written for these operating systems from source code. In addition to the POSIX system, Cygwin includes a package manager that connects to a repository with 9000+ software packages. Users can optionally use Cygwin ports repository which includes >2300 (86x64) to >2700 (86x32) more software packages not included in the RedHat-hosted repository, including many graphical user interface (GUI) applications. The repository contains a wide range of software, including Bash (command shell and scripting environment comparable to the Windows PowerShell), the GNU compiler collection with the complete tool chain. Further, the 'usual and customary' programming languages installed with a Linux distribution, including C, C++, Python, PHP, Perl, Tcl/Tk, and Lua are available, along with multiple development libraries. In addition to Bash, the GNU Utilities (e.g., find utilities, such as locate, find, grep) are installed by default. Hundreds of other software packages are included, many with non-POSIX Windows implementation, such as database management systems (PostgreSQL, MySQL), web servers (e.g., Apache HTTP Server), firewalls, text processing utilities, and console mode applications. Further, a (reasonably stable) X.Org Server X Window System (X11) implementation exists with GTK and Qt libraries. Based on these, graphic desktop managers, including GNOME, LXDE, LXQt, KDE, and others (e.g., x2go) with associated graphic user applications with variable stability and function.

Windows Wine: Available for most POSIX compliant (Unix-like) operating systems, such as Linux, Berkeley Software Distribution (BSD), and macOS (Darling and Darwine projects). It provides a Win32 API and cleanroom implementation of the associated functions. In contrast to Cygwin, Wine enables the installation and use of unaltered Windows software. Considerable effort has been put into support for video games, including third-party extensions (e.g., PlayOnLinux) which provide custom Windows configurations known to work with a very large list of video games. Further, office productivity software, including Microsoft Office, is supported. Because of the lack of dependence on the Windows registry, inclusion of statically linked libraries, and (at least in part) historic development from open source projects, portable application, such as the PortableApps platform and the 300+ available software applications which can be downloaded with it, work with little or no issues.

Worked examples

Example 1 — a first encounter with List of emulators

Start with the simplest possible case. Write down what List of emulators claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to List of emulators before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about List of emulators ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of List of emulators

In research: List of emulators appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses List of emulators in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: List of emulators is common in secondary-school and first-year university syllabi. It links to neighbouring topics Emulation software, Lists of software, so understanding it makes those chapters shorter.
In everyday life: Look for List of emulators outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
