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 ...
CPU Process Scheduling
CPU scheduling is the basis of multiprogrammed operating systems. By switching the CPU among processes, the operating system can make the computer more productive. More ...
AMD's Phenom II Processor
Phenom II is AMD's family of 45 nm multi-core processors and is the successor to the original Phenom. In the Phenom II, the shared L3 cache increased from 2MB to 6MB. The chip has an integrated, dual-channel memory controller that supports DDR3 RAM, and 4000MHz HyperTransport technology. 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 ...
Microcontrollers
A microcontroller is an IC that contains a microprocessor as well as RAM, ROM and general I/O ports. Engineers design microcontrollers into specific-purpose devices such as microwave ovens, cars, washing machines, refridgerators, and even space probes. 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 ...
Basic Decoder Circuitry
A microprocessors is a circuit that reads and execute program instructions called opcodes. A decoder is a circuit that converts an opcode into signals tused to control the circuitry of the microprocessor to enable it to perform the instruction. 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 ...
The Microcontroller Memory Map
a microcontroller is a set of resources. Each resource is identified by one or more addresses in an address space. The memory map is a graphic representation of how the resources are associated with addresses. 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 ...
Digital Logic Levels and Transfer Characteristics
A digital system uses discrete logic levels, 0 and 1, while the real world is a continuous range such as a voltage from 0 to 5. To make design easier, engineers view the system in the abstract. 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 ...
