CPU Process Memory Address Binding
For a program to run on a CPU it must be brought from files in long-term, non-volatile storage to main memory. Addresses in the source program must be mapped to addresses in main memory. 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 ...
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 ...
Operating System File Management
The operating system abstracts from the physical properties of its storage devices to define a logical storage unit, the file. The operating system maps files onto physical media and accesses these files via the storage devices. More ...
Microcontroller Registers
Registers are special small memory locations where the microcontroller can write data to or read data from. Special function registers help point to main memory locations, indicate the result of a mathematical operation, hold parts of an instruction or indicate the status of some operation or hardware feature. Some registers are general purpose and may be used by the programmer at their own discretion. 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 ...
Basic Computer Architecture
Basic computer architecture refers to the structure of a computer system and comprises its hardware, firmware, and software. Hardware consists of the physical components in computer architecture. The main hardware components of the computer architecture include the CPU, memory, and bus. More ...
Digital Logic Semiconductor Families
logic family refers to the way the semiconductors are designed to create gates. The first highly popular logic family, available in 1964, was TTL (Transistor-Transistor Logic). More ...
Microcontroller's Parallel I/O System
The most common way for microcontrollers to interact with the outside world is the The digital I/O lines. More ...
Using The I2C Bus
The I2C bus is used for communications between individual integrated circuits located on the same PCB. The I2C protocol supports multi-master, multi-slave communication, which means you can add a lot of functionality to your design. More ...
Microcontroller Architectures
The fundamental microcontroller architectures are Von Neumann and Harvard. More ...
Data Structures - Linked List, Stack, Queue, and Tree
An array is a simple data structure in which each element can be accessed directly. But what about storing an item whose size may vary? And what about removing an item if the relative positions of the remaining items must be preserved? In such situations other data structures may be needed. More ...
