Oscilloscope Required for Serious Digital Electronics Work
The oscilloscope is an instrument that displays digital signals on a line graph with time on the horizontal axis and voltage on the vertical axis. It will be difficult to do digital logic design without the use of an oscilloscope. More ...
Round-Robin CPU Scheduling Algorithm
CPU Scheduling deals with the problem of deciding which of the processes in the ready queue is to be alocated the CPU. There are many different CPU scheduling algorithms. In this article we describe round-robin CPU scheduling. More ...
The Many Processes of Silicon Wafer Manufacturing
A silicon wafer is a thin, circular disc used in the manufacture of integrated circuits and semiconductors. The silicon wafer manufacturing process is interesting. 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 ...
Digital Logic Transfer Characteristics
In the real world, gates don't transfer logic levels instantaneously. The time it takes for electrons and holes to move through the semiconductor material (called propagation delay) in CMOS are less than 100 ps (pico seconds), but there are other delays caused by resistance, capacitance, and inductance. More ...
Microprocessor Registers
To a large extent the operation of a microprocessor involves loading, transferring, and manipulating the contents of registers. In this article you learn about the functions, and purposes of the register set of the Intel 8086 microprocessor. More ...
Computer Buses
A 16-bit bus can transfer 16 binary bits simultainiously. This requires 16 separate metal traces on a PC board. We also need traces for control signals. The whole group of traces is referred to as a bus. More ...
AMD's Phenom Processor
Since 2005 AMD has used the Athlon name for their processors. This changed in 2007 when they released their new processor called Phenom. So we must ask the question; what is the difference between the Athlon and the Phenom? More ...
Microcontroller Architectures
The fundamental microcontroller architectures are Von Neumann and Harvard. More ...
Getting started with Raspberry Pi
So you have a Raspberry Pi, or you're thinking of getting one, and you want to know how to get started and how to become a master user of one. More ...
Basic Electronics for Computer Architecture
To understand computer architecture, it is necessary for you to have a basic understanding of electronics. This article explains how all the amazing things that can be done with electronics are the result of one simple thing - electric charge. More ...
Logical Versus Physical Memory Addresses
Computers use logical and physical addresses to access memory locatiuons. The CPU generates logical addresses. At run-time the Memory Management Unit (MMU) maps logical addresses to physical addresses. More ...
