v. t. e. 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.
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.
Many instruction set architectures have instructions that, on some implementations of that instruction set architecture, operate on half and/or twice the size of the processor's major internal datapaths. Examples of this are the Z80, MC68000, and the IBM System/360. On these types of implementations, a twice as wide operation typically also ...
Instructional design (ID), also known as instructional systems design and originally known as instructional systems development (ISD), is the practice of systematically designing, developing and delivering instructional materials and experiences, both digital and physical, in a consistent and reliable fashion toward an efficient, effective, appealing, engaging and inspiring acquisition of ...
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 computer (CISC), a RISC computer might require more instructions (more code) in ...
Base instruction. 0xFE 0x04. clt. Push 1 (of type int32) if value1 l ower than value2, else push 0. Base instruction. 0xFE 0x05. clt.un. Push 1 (of type int32) if value1 l ower than value2, un signed or un ordered, else push 0. Base instruction.
Single instruction, multiple data. Single instruction, multiple data (SIMD) is a type of parallel processing in Flynn's taxonomy. SIMD can be internal (part of the hardware design) and it can be directly accessible through an instruction set architecture (ISA), but it should not be confused with an ISA.
Customer proprietary network information ( CPNI) is the data collected by telecommunications companies about a consumer's telephone calls. [1] It includes the time, date, duration and destination number of each call, the type of network a consumer subscribes to, and certain other information that appears on the consumer's telephone bill.
