QEMU

QEMU is an exceptional processor emulator that gives a high level of performance by using dynamic translation. Aside from, it is easy to port to new host CPUs, making it an ideal choice for a broad range of applications.

In user mode emulation, QEMU launches Linux processes compiled for one CPU on another CPU. Notably, it converts Linux system calls because of endianness and 32/64 bit mismatches. This helps to create a more seamless experience for the user.

Moreover, QEMU has a full system emulation mode that emulates an entire system, including a processor and various peripherals. This feature makes it possible to create virtual machines that provide a complete computing environment for applications, operating systems, and hardware platforms.

Overall, QEMU is a versatile and powerful software that comes in handy for developers, hobbyists, and organizations that require a highly customizable and efficient processor emulator. Its user mode emulation and full system emulation modes make it a top choice among professionals who prioritize performance, flexibility, and scalability.
