The Quick Emulator (QEMU) [4] is a free and open-source emulator that uses dynamic binary translation to emulate a computer's processor; that is, it translates the emulated binary codes to an equivalent binary format which is executed by the machine.
The host in this article is the system running the emulator, and the guest is the system being emulated. The list is organized by guest operating system (the system being emulated), grouped by word length. Each section contains a list of emulators capable of emulating the specified guest, details of the range of guest systems able to be ...
Some other products such as VMware and Virtual PC use similar approaches to Bochs and QEMU, however they use a number of advanced techniques to shortcut most of the calls directly to the CPU (similar to the process that JIT compiler uses) to bring the speed to near native in most cases.
In December of 2022, Internet user Martijn de Vos, also known as devos50 has reverse engineered this device to successfully create a QEMU emulation of this device, running iPhone OS 1.0. [10] touchHLE is a compatibility layer (referred to as a “high-level emulator”) for Windows and macOS made by Andrea "hikari_no_yume" in early 2023.
SeaBIOS also runs inside an emulator; it is the default BIOS for the QEMU and KVM virtualization environments, and can be used with the Bochs emulator. It is also included in some Chromebooks , although it is not used by ChromeOS .
In computer science, dynamic recompilation is a feature of some emulators and virtual machines, where the system may recompile some part of a program during execution. By compiling during execution, the system can tailor the generated code to reflect the program's run-time environment, and potentially produce more efficient code by exploiting information that is not available to a traditional ...
ARM Fastsim, an instruction-set simulator and set of system models for ARM IP.; Gem5, an open source full-system and ISA simulator and framework.; OVPsim, a full-system simulation framework which is free for non-commercial use, and which comes with over 100 open source models and platforms that run Linux, Android, and many other operating systems.
The QEMU PC emulator version 0.9.1 can emulate the MIPS Magnum (and Acer Pica 61) using the "-M" parameter ("-M magnum" or "-M pica61"). QEMU can run the MIPS-compiled version of Debian Linux on an x86 platform, along with Windows NT 3.5, 3.51 and 4.0.
