In computing, firmware is software that provides low-level control of computing device hardware. For a relatively simple device, firmware may perform all control, monitoring and data manipulation functionality. For a more complex device, firmware may provide relatively low-level control as well as hardware abstraction services to higher-level ...
Hypervisor. A hypervisor, also known as a virtual machine monitor ( VMM) or virtualizer, is a type of computer software, firmware or hardware that creates and runs virtual machines. A computer on which a hypervisor runs one or more virtual machines is called a host machine, and each virtual machine is called a guest machine.
An emulator typically enables the host system to run software or use peripheral devices designed for the guest system. Emulation refers to the ability of a computer program in an electronic device to emulate (or imitate) another program or device. Many printers, for example, are designed to emulate HP LaserJet printers because so much software ...
Board support package. In embedded systems, a board support package ( BSP) is the layer of software containing hardware -specific boot firmware and device drivers and other routines that allow a given embedded operating system, for example a real-time operating system (RTOS), to function in a given hardware environment (a motherboard ...
A technology consisting of computer components and recording media used to retain digital data. It is a core function and fundamental component of computers. [ 1] device memory. local memory associated with a hardware device such as a graphics processing unit or OpenCL compute device, distinct from main memory.
A system on a chip or system-on-chip ( SoC / ˌˈɛsoʊsiː /; pl. SoCs / ˌˈɛsoʊsiːz /) is an integrated circuit that integrates most or all components of a computer or other electronic system. These components almost always include on-chip central processing unit (CPU), memory interfaces, input/output devices and interfaces, and secondary ...
coreboot. coreboot, formerly known as LinuxBIOS, [ 5] is a software project aimed at replacing proprietary firmware ( BIOS or UEFI) found in most computers with a lightweight firmware designed to perform only the minimum number of tasks necessary to load and run a modern 32-bit or 64-bit operating system .
