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 ...
Introduction to Computer System Main Memory Operation
The CPU can be shared by a set of processes. Using CPU scheduling, we can improve the utilization of the CPU and the speed of the computer's response. To realize this increase in performance, multiple processes must be kept in memory. More ...
Computer Buses
A 16-bit bus can transfer 16 binary bits simultainiously. This requires 16 separate metal traces on a PC board. We also need traces for control signals. The whole group of traces is referred to as a bus. More ...
Intoduction to Digital Electronics
The entire field of computer technology relies on transistors. This article describes how transistors are constructed and how modern MOSFETs are combined to make digital logic circuits. 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 ...
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 ...
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 ...
Digital to Analog Convertion with a Microcontroller
Digital to analog conversion (DAC) is the process by which a digital signal (expressed as a string of 1s and 0s) are converted to an analog signal (a continuously varying voltage). More ...
Fundamental Digital Logic Gates
All the advanced features of the most powerful computers, such as mulicore and parallel processing are done with digital logic. In this article I explain the fundamental concept of digital logic in simple and clear language so that anyone can understand it. More ...
Operating System Process Control Block
An Operating System Process is a program in execution. It includes the value in the program counter and in the processors registers. A process also includes a stack, data section, and a heap. Although two processes may be associated with the same program, they are considered two separate execution sequences. More ...
Learn Assembly Language Programming on Raspberry Pi 400
One of the easiest ways to learn assembly language programming is on the Raspberry Pi 400. The Raspberry Pi 400 is a complete personal computer built into a compact keyboard. More ...
Difference between Stack, Heap, and Queue
Stack, heap, and queue are ways that elements are stored in memory. Stack elements are added to the top of the stack, and removed from the top of the stack. The mnemonic LIFO is used to describe a stack (Last-In-First-Out). With a queue, the first one in is the first one out. The mnemonic FIFO is used to describe a queue. A heap is an area of memory where elements can be stored and removed in any order. More ...
