Instruction Set Architecture (ISA) is a set of instructions defined for the processor’s architecture. These are the instructions that the processor understands. It defines the hardware and software ...

Try to investigate the differences between the x86 and ARM processor families (or x86 and the Apple M1), and you'll see the acronyms CISC and RISC. It's a common way to frame the discussion, but not a ...

Some of the articles online are framing this as a CISC-versus-RISC battle, but that's an outdated comparison. The "classic" formulation of the x86 versus ARM debate goes back to two different methods ...

Renesas Technology Europe has announced that it has completed the design of an innovative new CISC (Complex Instruction Set Computer) CPU architecture that will deliver unmatched capabilities in code ...

Ten years ago, I waded into the then-raging “Mac vs. PC” wars with a lengthy treatise on “RISC vs. CISC: the Post-RISC Era.” In the conclusion to that article, I declared the “RISC vs. CISC” debate ...

Interrupt responsiveness, code execution predictability, and the ability to easily and quickly manipulate I/O pins and register bits are also important considerations. Standardized benchmarks such as ...

A computer processor uses a so-called Instruction Set Architecture to talk with the world outside of its own circuitry. This ISA consists of a number of instructions, which essentially define the ...

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 ...
