Tip The word "microarchitecture" is sometimes abbreviatedµarch. The Greek letterµ("mu") is the scientific abbreviation for "micro." Because this letter does not appear on some keyboards, the abbreviationuarchmay also be used. Architecture,Bus,Computer abbreviations,Computer instructions,Hardware terms
Intel Corp. is the world's largest manufacturer of central processing units and semiconductors. The company is best known for CPUs based on its x86 architecture, which was created in the 1980s and has been continuously modified, revised and modernized. Intel also offers graphics processing units ...
Apple’s latest generation big core CPU design inside of the A14 is codenamed “Firestorm”, following up last year’s “Lightning” microarchitecture inside of the Apple A13. The new Firestorm core and its years long pedigree from continued generational improvements lies at the heart of today’...
The goal of CISC is to provide a comprehensive set of instructions to handle a wide range of tasks, potentially reducing the number of instructions a programmer needs to write. Examples of CISC processors include Intel’s x86 processors, which are used in most personal computers, and Motorola 6...

Each CPU includes an ISA that specifies what the processor can do. The ISA is built into the CPU as part of its microarchitecture and serves as an interface between the computer's hardware and software. The ISA defines the set of commands that can be performed by the CPU. The machine cod...
The compiler supports Intel Core microarchitecture. The compiler contains tuning for the Intel Core microarchitecture during code generation. By default, this tuning is on and cannot be disabled as it also helps Pentium 4 and other processors. Intrinsics support newer AMD and Intel processors. Several...
Conversely, if the guess is wrong, the processor must now discard any transient operations that it has performed as a result of miss-speculation. It will then recompute the correct result. All of this happens under the hood, in the processor implementation, the so-called “microarchite...
Even CPUs that use the same ISA might use a different microarchitecture, another way that CPUs are designed, though not as fundamental as the ISA. Different microarchitectures offer different levels of performance, efficiency, and features. Here's what makes the CPU unique: it's very good at ...
An example of an instruction set is the x86 instruction set, which is common on computers today. Different computer processors can use almost the same instruction set with different internal designs. The Intel Pentium and AMD Athlon processors use nearly the same x86 instruction set. An ...
