Shortest-Job-First 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 shortest-job-first scheduling. More ...
Challenges of Programming Multicore Systems
Operating system designers must write scheduling algorithms that use multiple processing cores and application programmers, mustmodify existing programs and design new programs that are multithreaded. 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 ...
Microcontroller Internal EEPROM (Electrically Erasable Programmable Read Only Memory) Memory
In some situations it is required that some program parameters such as configuration settings be keept after the system is powered off. This is made possible by including a EEPROM internally to the microcontroller. More ...
Integrated Circuit Design Flow
The process of integrated circuit design can be divided into stages: system design, logic design, circuit design, layout design, fabrication and testing. More ...
Pentium P5 Processor
The Pentium P5 processor was introduced in 1993 was the first superscalar processor. It featured two integer pipelines and a pipelined floating-point unit. This article describes other innovations introduced in the P5. More ...
The AMD Athlon 64 Processor
AMD's Athlon 64 processor, released in September 2003, was their first 64-bit processor targeted for the workstation market to compete with Intel's Pentium 4. AMD's first 64-bit processor was the Opteron, released earlier in April that same year, targeted for the server market to compete with Intel's Xeon processor. More ...
AMD's Phenom Processor
AMD released the first Phenom processor in 2007. Unlike Intel's Core 2 Quad processors, which are a multi-chip module (MCM) design, AMD's Phenom processors had all cores on the same silicon die. More ...
CPU Chip Packaging
Over the development time of the computer, several different designs of packaging for the CPU chip die have been used. Each type of packaging has its advantages and disadvantages. This article reviews some common packages that might still be in use. More ...
Introduction to Boolean Algebra
Boolean algebra is a system of mathematics in which the values of the variables can take on only one of two values, either 0 or 1. Similar to regular algebra, Boolean algebra can be used to simplify a mathematical expression. Since computer logic is also a system in which the values of the inputs and outputs can take on only one of two values, Boolean algebra can be used to simplify logic circuits. More ...
Electronic Circuits Basics
This article's main target is to teach the electronics language to readers that are not familiar with electronics by using a group of rules and simple equations that describe the behavior of every electronic component and the relationship between the components in the circuit. 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 ...
