The nRF51 Series SoCs is a family of low power Bluetooth chips from Nordic Semiconductor that is based on ARM Cortex cores. The nRF51822 has the Cortex M0 core and is used in a lot of products. [Loren ...

The registers inside the CPU, the machine code instruction set, and the ways in which the instructions interact with the registers and status flags are all intertwined. As you may recall, one of my ...

ARC's configurable processor adds the ability to run both 16 and 32-bit instructions on a 32-bit architecture, allowing designers to reduce memory requirements by up to 30%, resulting in both lower ...

The processor we will be considering in this tutorial is the MIPS processor. The MIPS processor, designed in 1984 by researchers at Stanford University, is a RISC (Reduced Instruction Set Computer) ...

IBM Corp. is open-sourcing the machine language at the heart of its OpenPower processor series, which is used, among others, in the world’s two fastest supercomputers. The move was revealed today by ...

When developing software for small microcontrollers, it is common to use assembly language in the final product. But there is still much value in prototyping the software and its algortihms in C. Here ...

Most of us will be familiar at some level with the operation of a basic CPU, usually through exposure to microprocessors of the type that find their way into our projects. We can look at its internal ...

This paper presents an instruction set simulator of an 8-bit, MCS-51 compatible CPU core, and shows how to use it in embedded software development process; Method to control and debug CPU using ...

We all think of the CPU as the "brains" of a computer, but what does that actually mean? What is going on inside with the billions of transistors that make your computer work? In this four-part series ...
