86Box is a low level x86 emulator that runs older operating systems and software designed for IBM PC systems and compatibles from 1981 through fairly recent system designs based on the PCI bus. Easy to use interface inspired by mainstream hypervisor software. Low level emulation of 8086-based processors up to the Pentium with focus on accuracy. Great range of customizability of virtual machines. Many available systems, such as the very first IBM PC 5150 from 1981, or the more obscure IBM PS/2 line of systems based on the Micro Channel Architecture. ...

...The project emulates key components of the PS1 architecture, including the MIPS R3000A CPU, GPU, DMA controller, and CD-ROM subsystem, all interconnected through a custom bus system. Unlike production-grade emulators, ProjectPSX is intentionally designed as a transparent and educational codebase, prioritizing simplicity and readability over full compatibility or performance optimization. It includes a software-based rasterizer for rendering 3D graphics and supports features such as memory cards, basic BIOS functionality, and controller input mapping. ...

...By each memory access during the instruction you have knowledge about how many cycles have passed so far. So you could sync up your other concurrent tasks before accessing system bus portable68k will no longer be continued as an individual project due to time constraints. This does not mean that there is no further development. I am constantly developing the 68k emulation as part of the project "Denise (C64/Amiga emulator)". The programming is independent of the parent project "Denise" and can be transferred to a completely different project without additional programming effort. ...

MQNIC ( Message Queue NIC ) Virtual Link Layer The Message Queue NIC project provides a virtual link layer for qemu/kvm based virtual machines. The virtual link layer provides transport using the Apache ActiveMQ message server or other message bus and eliminates the need for external IP infrastructure to support VM deployments. Based on the ivshmem technology originally developed by Cam Macdonell the mqnic drivers use zero copy vm<->host data transfers and the apache message server to provide low latency, high bandwidth IP support for virtual data centers while simplifying the provisioning of hosted IP. ...
