Unicorn Engine was created and released more than 7 years ago to the public. We launched Unicorn Engine under an open-source license with the goal of contributing to the community and helping as many people as possible with our code. Our team has worked hard to maintain and develop the project to its fullest potential. We are pleased to see Unicorn Engine becoming a de facto emulator and laying the foundation for various innovative works in academia and industry.
Mupen64Plus is a cross-platform plugin-based N64 emulator which is capable of accurately playing many games. Included are four MIPS R4300 CPU emulators, with dynamic recompilers for 32-bit x86 and 64-bit amd64 systems, and necessary plugins for audio, graphical rendering (RDP), signal co-processor (RSP), and input. There is 1 included OpenGL video plugin, called RiceVideo. There are 3 other excellent video plugins being maintained by wahrhaft, called Arachnoid, Glide64, and Z64.

QEMU is a generic and open source processor emulator which can emulate i386, x86_64, MIPS, MIPSEL, PowerPC and SPARC systems. In case of MIPS or MIPSEL, it can emulate a platform with an IDE controller, and IDE hard disk, an Ethernet card and a serial port. It still lacks a graphic card and screen support, so the installation is done through the emulated serial port.
This howto has been written for a Debian host system, but could be easily adapted for other distributions. It also has been written for a MIPS emulated system, but there are very few differences compared to a MIPSEL emulated system. They simply differ by the endianess (MIPS is big endian, MIPSEL is little endian). When not explicitely specified in this howto, just replace mips by mipsel.
There are many other sites that talk about how much CPU and Memory you need to run GNS3. But using Dynagen V0.11 and GNS3 V3.5 will use 100% of CPU. This is because the configuration file will spawn multiple dynamips hypervisors. I presumse that this allows better use of multicore processors,and is probably best for for MS Windows. For the following network layout:
Because each dynamips process seems to burn up 100% of CPU. I have been able to reduce this. Having four dynamips instances trying to grab CPU resources stoped me from using web browsing. By reducing the number of hypervisors to two, it works a lot more efficiently.
For this exercise we need to use a program called mips-gcc (a cross-compiler for MIPS) that allows us to compile programs for the MIPS architecture on our x86 machines. If you are doing this lab remotely, you should SSH into one of the hive machines.
A: The goal of my page here is to allow for testing on various CPUarchitectures. I realise that not all sub-architectures are covered (e.g.,armv4, sparc millennium, mips r6). Also, the machine type is largely ignored.I don't currently have plans to try to make it much more complete, as thatwould be hard to maintain in the long run. So, I'm afraid I can only wish youluck with machine M emulation.
A processor's architecture is a logical description of itscomponents and its basic operations.This says nothing about how the architecture is implemented.The operations need not be done in electronics.They can be done with software.A program that implements a processor'sarchitecture is the logical equivalent of an implementation in silicon.Such a program is called an emulator.Any computer can run an emulator of any kind of computer.Of course, somebody has to write the emulator, and that isdifficult.
The basic flow chart of an emulator programis the machine cycle ofthe emulated processor.But now the steps are implemented in software,not in silicon.The emulated machine cycle involves perhaps thousands of program statements.When the emulator is running, each simulated machinecycle requires the execution of many instructionson the host processor.So emulators run much slower than the processor they are emulating.
This course uses an emulator for the MIPS architecture.Using an emulator has many advantages over using theactual hardware.The biggest advantage is that the architecture describedin these notes will exactly match the architecture implementedby the emulator.You can download exactly what you need to use to follow thesenotes.The emulator runs on most common desktop computers;PC, Mac, or even ... MIPS.
However to test it, you will need to actually run it on a physical machine or use an emulator. I remember back in college, I write MIPS assembly on my x86 Linux laptop and it runs/debugs inside an emulator that emulates the mips cpu so again look towards what tool you are using. If you are writing anything higher than assembly, it is as simple as getting a cross compiler, avoid architecture and operating system specific(including avoiding any embedded assembly) and test the code on your native machine before cross compiling for other systems
If you are using a PowerPC-based system, applications will run at native speeds (i.e., without any emulation involved). On other systems, SheepShaver provides the first PowerPC G4 emulator, though without MMU, to enable the execution of Mac OS Classic. Performance with the current CPU emulator using basic just-in-time (JIT) translation techniques is roughly 1/8-th of native speeds.
I am new to Mac and I am looking for a Windows emulator for Mac OS X. I want to use an application which is not available for Mac.Please recommend the strengths and weaknesses (including cost) of the various options available.
When using the term "emulator", it is important to distinguish between something that acts like Windows to applications (like Wine/Crossover) and something that acts like a PC to Windows (most of the other solutions) so that Windows can be installed.
Q is a great lightweight CPU emulator for OS X. Oddly enough, it runs on PPC Macs, in addition to Intel Macs. It supports emulating x86, x86-64bit, PPC PowerMac, PPC PREP, SPARC32, MIPS, and ARM processors.
Thankfully QEMU has us covered. It's an open-source emulator that unlike regular virtualization tools is quite capable of emulating completely different CPU architectures from ARM through to MIPS, PowerPC, RISC-V, Sparc and even IBM's big s390x z/Architecture.
It's also nice to see an old friend again. Despite regularly finding myself on retro machines and emulators spanning 8 and 16 bit machines I don't have (or have the space for) a classic Mac and emulation has been difficult. I think I last used Mac OS 9 in 2000 on an iMac at work before we put the Mac OS X Public Beta on it (I was a bit NeXT/OpenStep fan and wanted to see what they had done to it!)
Gary Davidson, an expert in emulation, wrote an emulator for every new processor that was adopted. His software was based on the 90/10 theory of emulation. The theory centered around the observation that 10% of the software was being used 90% of the time, which meant that only a small portion of a program had to be run at a time. As a result, the emulators he created were very fast, typically as fast as a Mac IIci running 68k software.
Cognac had its breakthrough during the Christmas holiday (while the Tesseracht team was on vacation) when Gary Davidson completed the 68k emulator for the PowerPC (PPC) and ran the Mac OS in emulation on the prototype (housed in an LC case, it was named the RISC LC or RLC). 2ff7e9595c
