Priority 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 priority CPU scheduling. More ...
The AMD Athlon 64 X2 Processor
The Athlon 64 X2 is the first dual-core CPU manufactured by AMD.
It is essentially two Athlon 64 cores on one die joined together with additional control logic. The cores share one dual-channel memory controller. The benefit of dual-core processors is their ability to process more software threads at the same time. However, many programs are written with only one thread. More ...
Operating System Memory Paging
Paging is a memory management scheme that permits a process's physical address space to be noncontiguous. More ...
Analog to Digital Convertion with a Microcontroller
Analog-to-digital conversion (or A/D conversion), is an electronic process that converts a continuously variable signal into a digital signal (expressed as a string of 1s and 0s). More ...
Program Flow Charting
Depending upon the language used, program code my be difficult for humans to read and understand. However, one type of programming that is very easy to understand is flow charting. 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 ...
Direct Memory Access (DMA)
In early computers, all data transfers required the processor to read and write single words from memory until the entire transfer is complete. With DMA, the DMA controller takes control of the system buses to move data between the device and main memory. More ...
Real-Time CPU Scheduling
In a real-time systems, is one whose operation depends on timing. A task must be serviced within a specific time interval. The tasks and their execution times must all be known. More ...
Intel's Dual-Core Core i3 Processor
Core i3 is an entry-level 2-core processor using the 32nm Westmere micro-architecture. With a Thermal Design Power (TDP) of 73 watts, the i3-530 is a cool-running chip that doesn't gobble loads of electricity, so those looking for a power-efficient, quiet machine will be happy with it. More ...
Introduction to the Raspberry Pi
The Raspberry Pi is a tiny bare-bones computer motherboard. You can easily make it into a Linux PC by connecting your own keyboard, mouse, and display. More ...
