With backing from some of the largest technology companies, a major project called RISC-V seeks to facilitate open-source design for computer chips, offering the possibility of opening chip designs ...

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 ...

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 the ...

The topic of RISC-V custom instructions is growing in importance. This article explains why this subject is becoming so significant, and outlines some of the previous approaches to processor hardware ...

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, ...

This paper describes the design and implementation of a version of the 8051 microcontroller, one of the most commercially used microcontrollers in FPGA with reconfigurable instruction set.

Renesas Technology has added eight devices to its 32-bit Cisc (complex instruction set computer) microcontrollers which operate at up to 50MHz with a top-rated performance of 50MIPS. With more on-chip ...

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 ...
