For user-mode emulation, QEMU maps emulated threads to host threads. QEMU can run a host thread for each emulated virtual CPU (vCPU) for full system emulation. This depends on the guest being updated to support parallel system emulation, currently ARM, Alpha, HP-PA, PowerPC, RISC-V, s390x, x86, and Xtensa.
Bochs (pronounced "box") is a portable IA-32 and x86-64 IBM PC compatible emulator and debugger mostly written in C++ and distributed as free software under the GNU Lesser General Public License. It supports emulation of the processor(s) (including protected mode ), memory, disks, display, Ethernet , BIOS and common hardware peripherals of PCs .
Full system simulation with optional component virtualization Software development (early, embedded), advanced debug for single and multicore software, compiler and other tool development, computer architecture research, hobbyist Depends on target architecture (full and slow hardware emulation for guests incompatible with host) [citation needed]
Mednafen (My Emulator Doesn't Need A Frickin' Excellent Name), formerly known as Nintencer, is an OpenGL and SDL multi-system free software wrapper that bundles various original and third-party emulation cores into a single package, and is driven by command-line input. [2] [3] It is distributed under the terms of the GPL-2.0-or-later license. [4]
SIMH was based on a much older systems emulator called MIMIC, which was written in the late 1960s at Applied Data Research. [1] SIMH was started in 1993 with the purpose of preserving minicomputer hardware and software that was fading into obscurity.
Gavare's eXperimental Emulator (formerly known as mips64emul) is a computer architecture emulator being developed by Anders Gavare. It is available as free software under a revised BSD-style license. In 2005, Gavare changed the name of the software project from mips64emul to GXemul.
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.
