For example, a number of older Apple II games did not work correctly on the newer Apple IIc, because the latter used a newer CPU revision – 65C02 – that did away with illegal opcodes. Later CPUs, such as the 80186 , 80286 , 68000 and its descendants, do not have illegal opcodes that are widely known/used.
In computing, hardware overlay, a type of video overlay, provides a method of rendering an image to a display screen with a dedicated memory buffer inside computer video hardware. The technique aims to improve the display of a fast-moving video image — such as a computer game , a DVD , or the signal from a TV card .
Unlike a local game where the inputs of all players are executed instantly in the same simulation or instance of the game, in an online game there are several parallel simulations (one for each player) where the inputs from their respective players are received instantly, while the inputs for the same frame from other players arrive with a certain delay (greater or lesser depending on the ...
CPU-Z is more comprehensive in virtually all areas compared to the tools provided in the Windows to identify various hardware components, and thus assists in identifying certain components without the need of opening the case; particularly the core revision and RAM clock rate. It also provides information on the system's GPU.
Transient execution CPU vulnerabilities are vulnerabilities in which instructions, most often optimized using speculative execution, are executed temporarily by a microprocessor, without committing their results due to a misprediction or error, resulting in leaking secret data to an unauthorized party.
Heatsink mounted on a motherboard, cooling the CPU underneath it. This heatsink is designed with the cooling capacity matching the CPU’s TDP. Thermal Design Power ( TDP ), also known as thermal design point , is the maximum amount of heat that a computer component (like a CPU , GPU or system on a chip ) can generate and that its cooling ...
On the x86 computer architecture, a triple fault is a special kind of exception generated by the CPU when an exception occurs while the CPU is trying to invoke the double fault exception handler, which itself handles exceptions occurring while trying to invoke a regular exception handler.
Both dynamic and short-circuit power consumption are dependent on the clock frequency, while the leakage current is dependent on the CPU supply voltage. It has been shown that the energy consumption of a program shows convex energy behavior, meaning that there exists an optimal CPU frequency at which energy consumption is minimal for the work done.
