2. x86 assembly language - Wikipedia

   en.wikipedia.org/wiki/X86_assembly_language

   x86 assembly language is the name for the family of assembly languages which provide some level of backward compatibility with CPUs back to the Intel 8008 microprocessor, which was launched in April 1972. [1] [2] It is used to produce object code for the x86 class of processors. Regarded as a programming language, assembly is machine-specific ...

3. Instruction set architecture - Wikipedia

   en.wikipedia.org/wiki/Instruction_set_architecture

   Machine code. In computer science, an instruction set architecture ( ISA) is an abstract model that generally defines how software controls the CPU in a computer or a family of computers. [ 1] A device or program that executes instructions described by that ISA, such as a central processing unit (CPU), is called an implementation of that ISA.

4. x86 instruction listings - Wikipedia

   en.wikipedia.org/wiki/X86_instruction_listings

   Cryptographic (e.g. RDRAND, AES-NI) Discontinued (e.g. 3DNow!, MPX, XOP) v. t. e. The x86 instruction set refers to the set of instructions that x86 -compatible microprocessors support. The instructions are usually part of an executable program, often stored as a computer file and executed on the processor.

5. Reduced instruction set computer - Wikipedia

   en.wikipedia.org/wiki/Reduced_instruction_set...

   The Sun Microsystems UltraSPARC processor is a type of RISC microprocessor. In electronics and computer science, a reduced instruction set computer ( RISC) is a computer architecture designed to simplify the individual instructions given to the computer to accomplish tasks. Compared to the instructions given to a complex instruction set ...

6. Word (computer architecture) - Wikipedia

   en.wikipedia.org/wiki/Word_(computer_architecture)

   For the linguistics term "question word", see Interrogative word. In computing, a word is the natural unit of data used by a particular processor design. A word is a fixed-sized datum handled as a unit by the instruction set or the hardware of the processor. The number of bits or digits [ a ] in a word (the word size, word width, or word length ...

7. Complex instruction set computer - Wikipedia

   en.wikipedia.org/wiki/Complex_instruction_set...

   Complex instruction set computer. A complex instruction set computer ( CISC / ˈsɪsk /) is a computer architecture in which single instructions can execute several low-level operations (such as a load from memory, an arithmetic operation, and a memory store) or are capable of multi-step operations or addressing modes within single instructions ...

8. Comparison of instruction set architectures - Wikipedia

   en.wikipedia.org/wiki/Comparison_of_instruction...

   An instruction set architecture ( ISA) is an abstract model of a computer, also referred to as computer architecture. A realization of an ISA is called an implementation. An ISA permits multiple implementations that may vary in performance, physical size, and monetary cost (among other things); because the ISA serves as the interface between ...

9. Compressed instruction set - Wikipedia

   en.wikipedia.org/wiki/Compressed_instruction_set

   A compressed instruction set, or simply compressed instructions, are a variation on a microprocessor 's instruction set architecture (ISA) that allows instructions to be represented in a more compact format. In most real-world examples, compressed instructions are 16 bits long in a processor that would otherwise use 32-bit instructions.
