Simplified Windows Architecture Overview
A simplified overview of the Windows operating system architecture divides it into user-mode and kernel-mode components. More ...
Load Balancing Multiple CPUs in Symmetric Multiprocessing
On Symmetric Multiprocessing (SMP) systems it is important to keep the workload balanced among all processors. There are two approaches to accomplish this, push migration and pull migration. More ...
The Motherboard Chipset
Because the chipset dictates the bus speed, type and amount of memory, and the type and number of I/O ports, much of a computer's performance is determined by its chipset. More ...
Intel's Sandy Bridge Micro-Architecture
"Sandy Bridge" is Intel's code name for a new cpu core microarchitecture. It introduces a few new or improved features. The memory controller, the PCI Express controller, and video circuitry are all located within the processor die and the new ring architecture uses a Last Level Cache between the CPU and graphics cores. More ...
Arduino Microcontroller Development Platform
The benefit of the open source Arduino Microcontroller Development Platform is that the software is free and the hardware is cheap. This makes it one of the cheapest platforms on which to develop prototypes. 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 ...
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 ...
Basic Computer Architecture
Computers today, even that PC on your desk are unbelievably complex. You can't understand computers without an understanding of the basics. In this article I explain basic computer architecture in simple, basic terms. 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 ...
How Computer Memory Works
Every program being executed and every piece of data being manipulated must be copied from a storage device, such as a magnetic disk, into main memory. It's important to understand the basic types of memory. More ...
Processor Affinity in Symmetric Multiprocessing
Processor Affinity refers to a process's tendency to continue running on the processor on which it is currently running. When a process executes on a CPU, that process's cache is populated with its most recently accessed data, if a process is moved to a different CPU, that second processor's cache must be populated with that data. 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 ...
