An Instruction Set Architecture (ISA) defines the software interface through which for example a central processor unit (CPU) is controlled. Unlike early computer systems which didn’t define a ...

In short, an instruction set is the link between a computer’s software and hardware. It’s a set of basic instructions that a processor understands. Furthermore, it’s about functional definition of ...

IBM solved this problem with the introduction of the Instruction Set Architecture (ISA) and the microcode engine in the 60s. Specifically, the launch of the microcoded IBM System/360 ushered in ...

An instruction set architecture (ISA) defines the set of basic operations a computer must support. This includes the functional definition of operations and precise descriptions of how to invoke and ...

Reduced Instruction Set Computer, or RISC, is a processor architecture that uses a simplified instruction set that leads to faster execution of programs. This term was viewed 4,997 times ...

In computer science, an instruction set architecture (ISA) is an abstract model of a computer. It’s also referred to as architecture or computer architecture. Moreover, a central processing unit (CPU) ...

Evaluation methodology/metrics and caveats, instruction set design, advanced pipelining, instruction level parallelism, prediction-based techniques, alternative architectures (VLIW, Vector and SIMD), ...

x86, the mainstream instruction set architecture for PC CPUs, originated from the Intel 8086 processor and has been in use for 46 years. Technology blog Hackaday claims that x86 will be extinct in ...

Programs are compiled into a set of low-level instructions called assembly language as part of an Instruction Set Architecture (ISA). This is the set of instructions that the CPU is built to ...

Why it matters: Intel is gearing up for what the company considers the "next major step" in the evolution of the original x86 instruction set architecture (ISA).
