The instruction set provides the encoding and semantics, but it doesn't specify how it's implemented, leading to the plethora of RISC-V cores, chips, and boards.

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 ...

Rather than extend its 32-bit instruction set, Arm offers a clean 64-bit implementation. To accomplish this, the ARMv8 architecture uses two execution states, AArch32 and AArch64.

RISC-V is an instruction set architecture for processors that offers innovative operational mechanisms. Learn about its background and the advantages it brings.

Synopsys' ASIP design tools enable rapid exploration and optimization of processor architectures KYOCERA created a custom high-performance DSP in less than a year, saving an estimated nine months on ...

Instruction set architecture (ISA): A blueprint defining how a processor executes commands. RISC-V is an open ISA for flexible chip design, while the EVM uses a custom software-based ISA for smart ...

Most processors run a single instruction set. But the ARM1026EJ-S implements four in hardware, including 32-bit ARM instructions, 16-bit ARM Thumb instructions, ARM DSP instructions ...

A recent study led by Princeton University researchers, in collaboration with University of Maryland and IBM, explored the architectural design of quantum computers (QC). In a paper presented at ...

Intel and AMD took over the server processor market in the mid-2000s. This happened after AMD introduced 64-bit instructions into the x86 instruction set with its Opteron processor architecture.
