UTM (software)
UTM is an open-source virtual machine application for macOS and iOS. A version called UTM SE was released on the iOS App Store, which is noted for its slow performance compared to the regular version. UTM has been praised for its ability to run a large number of operating systems for free. Features UTM functions as either a virtualizer or an emulator. As a virtualizer, UTM runs operating systems that have an underlying architecture compatible with the physical device by directly running the virtual machine code on the host CPU. As an emulator, UTM can run operating systems with a different underlying architecture by running just-in-time compilation on the guest code. UTM can integrate with the built-in hypervisor on macOS for virtualization, and it also supports QEMU as a back-end for both virtualization and emulation. QEMU allows UTM to emulate a wide variety of operating systems. When connected to Apple's built-in hypervisor, UTM can use macOS's Rosetta software to efficientl ...

ARM Processor
ARM (stylised in lowercase as arm, formerly an acronym for Advanced RISC Machines and originally Acorn RISC Machine) is a family of RISC instruction set architectures (ISAs) for computer processors. Arm Holdings develops the ISAs and licenses them to other companies, who build the physical devices that use the instruction set. It also designs and licenses cores that implement these ISAs. Due to their low costs, low power consumption, and low heat generation, ARM processors are useful for light, portable, battery-powered devices, including smartphones, laptops, and tablet computers, as well as embedded systems. However, ARM processors are also used for desktops and servers, including Fugaku, the world's fastest supercomputer from 2020 to 2022. With over 230 billion ARM chips produced, , ARM is the most widely used family of instruction set architectures. There have been several generations of the ARM design. The original ARM1 used a 32-bit internal structure but had a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Interpreter (computing)
In computer science, an interpreter is a computer program that directly executes instructions written in a programming or scripting language, without requiring them previously to have been compiled into a machine language program. An interpreter generally uses one of the following strategies for program execution: # Parse the source code and perform its behavior directly; # Translate source code into some efficient intermediate representation or object code and immediately execute that; # Explicitly execute stored precompiled bytecode made by a compiler and matched with the interpreter's virtual machine. Early versions of Lisp programming language and minicomputer and microcomputer BASIC dialects would be examples of the first type. Perl, Raku, Python, MATLAB, and Ruby are examples of the second, while UCSD Pascal is an example of the third type. Source programs are compiled ahead of time and stored as machine independent code, which is then linked at run-ti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Delta (emulator)
Delta is a video game console emulator created by Riley Testut for iOS and iPadOS. It supports games for the Super Nintendo Entertainment System, Nintendo Entertainment System, Nintendo 64, Nintendo DS, Game Boy, Game Boy Color, and Game Boy Advance. A paid version of the emulator also supports Sega Genesis games. Development of Delta started prior to Testut entering university, with it being a successor to the earlier GBA4iOS application. Prior to the application's release on the App Store, iOS users had to download Delta via AltStore, Testut's app store for the iOS and iPadOS operating systems. Upon release onto the App Store in April 2024, the app reached the top of the App Store rankings for about two weeks. Background Riley Testut started developing GBA4iOS, the predecessor of Delta, during his senior year at Richardson High School along with his friend Paul Thorsen. It was a emulator of the Game Boy Advance for the iPhone. iOS users had to sideload the emulator via a l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Video Game Console Emulator
A video game console emulator is a type of emulator that allows a computing device to emulate a video game console's hardware and play its games on the emulating platform. More often than not, emulators carry additional features that surpass limitations of the original hardware, such as broader controller compatibility, timescale control (such as fast-forwarding and rewinding), easier access to memory modifications (like GameShark), and unlocking of gameplay features. Emulators are also a useful tool in the development process of homebrew demos and the creation of new games for older, discontinued, or rare consoles. The code and data of a game are typically supplied to the emulator by means of a ROM file (a copy of game cartridge data) or an ISO image (a copy of optical media). While emulation softwares themselves are legal as long as they don't infringe copyright protections on the console, emulating games is only so when legitimately purchasing the game physically and ...

Sideloading
Sideloading describes the process of transferring files between two local devices, in particular between a personal computer and a mobile device such as a mobile phone, smartphone, PDA, tablet, portable media player or e-reader. Sideloading typically refers to media file transfer to a mobile device via USB, Bluetooth, WiFi or by writing to a memory card for insertion into the mobile device, but also applies to the transfer of apps from web sources that are not vendor-approved. When referring to Android apps, "sideloading" typically means installing an application package in APK format onto an Android device. Such packages are usually downloaded from websites other than the official app store Google Play. For Android users sideloading of apps is only possible if the user has allowed "Unknown Sources" in their Security Settings. When referring to iOS apps, "sideloading" means installing an app in IPA format onto an Apple device, usually through the use of a computer program ...

DirectX
Microsoft DirectX is a collection of application programming interfaces (APIs) for handling tasks related to multimedia, especially game programming and video, on Microsoft platforms. Originally, the names of these APIs all began with "Direct", such as Direct3D, DirectDraw, DirectMusic, DirectPlay, DirectSound, and so forth. The name ''DirectX'' was coined as a shorthand term for all of these APIs (the ''X'' standing in for the particular API names) and soon became the name of the collection. When Microsoft later set out to develop a Video game console, gaming console, the ''X'' was used as the basis of the name Xbox (console), Xbox to indicate that the console was based on DirectX technology. The ''X'' initial has been carried forward in the naming of APIs designed for the Xbox such as DirectInput, XInput and the Cross-platform Audio Creation Tool (XACT), while the DirectX pattern has been continued for Windows APIs such as Direct2D and DirectWrite. Direct3D (the 3D graphics A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hardware Acceleration
Hardware acceleration is the use of computer hardware designed to perform specific functions more efficiently when compared to software running on a general-purpose central processing unit (CPU). Any transformation of data that can be calculated in software running on a generic CPU can also be calculated in custom-made hardware, or in some mix of both. To perform computing tasks more efficiently, generally one can invest time and money in improving the software, improving the hardware, or both. There are various approaches with advantages and disadvantages in terms of decreased latency, increased throughput, and reduced energy consumption. Typical advantages of focusing on software may include greater versatility, more rapid development, lower non-recurring engineering costs, heightened portability, and ease of updating features or patching bugs, at the cost of overhead to compute general operations. Advantages of focusing on hardware may include speedup, reduced power c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GPU Virtualization
GPU virtualization refers to technologies that allow the use of a GPU to accelerate graphics or GPGPU applications running on a virtual machine. GPU virtualization is used in various applications such as desktop virtualization, cloud gaming and computational science (e.g. hydrodynamics simulations). GPU virtualization implementations generally involve one or more of the following techniques: device emulation, API remoting, fixed pass-through and mediated pass-through. Each technique presents different trade-offs regarding virtual machine to GPU consolidation ratio, graphics acceleration, rendering fidelity and feature support, portability to different hardware, isolation between virtual machines, and support for suspending/resuming and live migration. API remoting In API remoting or API forwarding, calls to graphical APIs from guest applications are forwarded to the host by remote procedure call, and the host then executes graphical commands from multiple guests using the h ...
