Binary Number Representation and Binary Math
Computers perform all of their amazing work with only two voltage levels, one representing binary 0, the other representing binary 1. This article describes how to perform binary addition and subtraction. More ...
Microcontroller's Parallel I/O System
The most common way for microcontrollers to interact with the outside world is the The digital I/O lines. More ...
ARM Cortex-A72 Registers
16 registers r0 - r15 are accessable in the ARM Cortex-A72 user mode. In addition part of the CPSR (Current Program Status Register) is accessable. That part is the APSR (Application Program Status Register) which contains conditional status bits. More ...
Digital Logic Semiconductor Families
logic family refers to the way the semiconductors are designed to create gates. The first highly popular logic family, available in 1964, was TTL (Transistor-Transistor Logic). More ...
Inductors in DC Circuits
An inductor is constructed with a coil of wire. When connected to a voltage source, an inductor resists a change in current flow as it stores energy in its magnetic field, and it can return that energy to the circuit if desired. More ...
The Use of SOI (Silicone on Insulator) Wafers in MEMS (Micro-Electro-Mechanical Systems) Production
The main advantage of Silicone on Insulator (SOI) technology is that they enable the manufacture of smaller devices. The manufacturing process optimizes the efficiency of transistors and allows chips to be packed close together, resulting in a greater yield per wafer. More ...
Intel Celeron D Processor
The Celeron processor is a budget processor offering moderate performance at an affordable price. The Celeron processor is suitable for use in notebook and desktop computers running home-office applications and providing access to the Internet. More ...
Operating System Process Scheduling Queues
The objective of multiprogramming is to have some process running at all times, to maximize CPU utilization. To meet these objectives, the process scheduler selects a process from a queue for execution on the CPU. More ...
Binary Floating-Point Numbers
Floating-point numbers allow you to use the very large, and very small, numbers commonly found in scientific calculations. A binary floating-point number consists of three parts, the sign bit, the mantissa and the exponent. More ...
Operating System Services
An operating system provides an environment for the execution of programs. It provides certain services to programs and to the users of those programs. These operating system services are provided for the convenience of the programmer, to make the programming task easier. More ...
The Microcontroller's Asynchronous Serial Interface
An Asynchronous Serial Interface sends data one bit at a time, as apposed to a parallel interface which send one byte or one word at a time, and asynchronous means it sends them when its ready, without reference to a clock signal. More ...
Factors in Choosing an Oscilloscope
An oscilloscope is an instrument used to display the waveform of electronic signals. It draws a graph of the voltage as a function of time. A digital oscilloscope can also store waveforms and perform mathematical analysis of the waveform. More ...
