List of instruction set architectures

Instruction Length Affected by Memory size/organization, register numbers, bus structure, etc Flexibility vs. Implementation ComplexityFlexibility vs. Implementation Complexity Memory-transfer consideration Fixed vs. non-fixed instructions Instruction Set The collection of different instructions CPU can understand and execute Different instructions What is the Instruction Set Architecture? 11 • Agreed-upon interface between all the software that runs on the machine and the hardware that executes it • Primitive set of instructions a particular CPU implements Processor Memory I/O system Compiler Operating System Application Digital Design Circuit Design Instruction Set Architecture ARM architecture is the most widely used instruction set architecture and the instruction set architecture produced in the largest quantity MIPS architecture is a 32 bit and 64 bit instruction set developed by MIPS Technologies and is often used in academic study OpenRISC is a set of open source instruction sets Answer (1 of 4): As of today, the two most widely used ISA (Instruction Set Architecture) are the Intel x86 and ARM architectures. 1. All of Intel and AMD processors (across desktop,laptops to servers) uses x86 ISA 2. ARM ISA is used by most of the mobile processors. 3. 1. This includes CPU cor - Arm® An Instruction Set Architecture (ISA) is part of the abstract model of a computer that defines how the CPU is controlled by the software. The ISA acts as an interface between the hardware and the software, specifying both what the processor is capable of doing as well as how it gets done. Following are the instruction set architectures: Reduced Instruction Set Computer (RISC) Complex Instruction Set Computer (CISC) Minimal instruction set computers (MISC) Very long instruction word (VLIW) Explicitly parallel instruction computing (EPIC) One instruction set computer (OISC) Zero instruction set computer (ZISC) An instruction set, or instruction set architecture (ISA), is a list of all the commands ( instructions ), with all their variations, that a processor can execute. Instructions include: Arithmetic such as add and subtract. Logic instructions such as and, or, and not. Data instructions such as move, input, output, load, and store. The ARM instruction set also has some decidedly non-RISC features. The most well-known is predicated instructions, which execute conditionally based on the state of one of the condition registers. In a typical implementation, they execute anyway, but the results are stored only if the condition codes are matched. Consider a typical pipelined CPU. Instruction Set Architecture. Download version 3.1b 2021-09-14. The Power Instruction Set Architecture (ISA) Version is a specification that describes the architecture used for the IBM POWER processor. It defines the instructions the processors execute. It is comprised of three books and a set of appendices. 2.2 Classifying Instruction Set Architectures 103 puters shipping today, keeps all operands in memory and is called a memory-memory architecture. Some instruction set architectures have more registers than a single accumulator, but place restrictions on uses of these special registers. Such an architecture is sometimes called an extended Instruction Set Architecture (ISA) Eco data soft. Computer organization and architecture Subesh Kumar Yadav.
