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 ...

In semiconductors, architecture refers to the instruction set architecture (ISA), a detailed set of rules and specifications governing how a chip processes data and executes instructions. This ISA ...

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 Apple job ad reveals that the company is exploring the use of RISC-V chips, an open-source processor tech that competes with the ARM architecture used for Apple’s A-series and M-series chips.

Last month, a team of Google security researchers released a tool that can modify microcode of AMD's processors based on the Zen microarchitecture, the Zentool. While this is a security vulnerability, ...

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 ...
