Emulator Development
Compute Express Link in QEMU
Driver Development for Fashionably Late Hardware
For years now, driver development has been starting earlier in the product life-cycle. Using QEMU for liberating driver developers from being bound to hardware schedules isn't new. Not so common however, is adding support for new hardware to QEMU while the spec is still being revised. The coupling of driver development and emulation development helped find spec issues early, and allowed us to submit patches for a basic driver on the day that the specification wasreleased.
This talk will discuss how we used QEMU to meet our goals, the challenges in enabling CXL 2.0 for QEMU, an review of what CXL is, an overview of the architecture and implementation, and ways in which we'd love to get help.

The open source emulation landscape is littered with abandoned projects. MAME has survived stock market crashes, a pandemic, major internal refactoring, half a dozen leadership changes, and persistent rumours of the project’s imminent death. Why is MAME still here? How does MAME continue to attract contributors? What are some of the issues a project this size faces?

The PlayStation 2, being the best-selling game console of all time, is a surprisingly complex beast. So, isn't it only fitting that its emulation in software is equally complicated? With PCSX2 developer GovanifY, we carefully peel back the layers of the world's most popular game console, and its most popular emulator. See why, twenty years later, it's now easier than ever to ＰＬ△︎Ｙ ＩＮ Ｙ◯︎ＵＲ Ｗ╳︎ＲＬ□.

Ever wanted to write an emulator? Or understand how they work? In this talk you learn how to start writing your own emulator from the ground up. You'll see the basic methods used to emulate CPUs, memory, and graphics cards. For the keen, we'll also cover advanced emulation techniques, licensing issues, and history.

Even to this day, there's something utterly captivating about bringing to life a piece of software effectively frozen in time, designed to run on what was originally a black box, by means of a device that one uses to check up on cat facts. Adding to this, it can even be enhanced and possibly perform better than its developers ever hoped for. If you also got to play around with your first computer in the early 2000s, chances are that console emulators were amongst the first pieces of software ...

Many emulators offer a CRT filter, an artist's rendition of classic video. This presentation describes emulation of the an entire NTSC or PAL video device, to produce an engineer's rendition — starting from sync discrimination and separation, through PLLs into scan placement and via QAM to extracting colour.

RetroArch is a free, open-source and cross-platform frontend for emulators, game engines, video games, media players and other applications. The libretro API is designed to be fast, lightweight, portable, and without dependencies. Due to the number of systems and games it can play under a single user interface, RetroArch has grown immensely over the years, and has been well adopted by the emulation scene.

I will demonstrate how to write a vectorized (parallel) Caesar cipher in RISC-V (in assembler) using the project's emulator. Using the emulator is necessary at this point for such an application because the vectorized extension to the RISC-V ISA is not standardized. I will further demonstrate how the emulator itself is able to emulate the execution of a single user-space application when it is actually designed to emulate an entire system. This will involve a demonstration and explanation of ...
