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 ...
Network on a Chip (NoC)
NoC (Network on a Chip) is a method of placing a much larger number of processors on a multi-core chip. Much like a regular network, NoC has multiple point-to-point data links that are interconnected by routing switches. More ...
Microprocessor Counter, Clock, Timer Circuits
All the circuitry in the microprocessor, in fact all the circuitry on the motherboard require a clock signal for operation. The clock signal is the heartbeat of the system. Without a clock signal, the microprocessor and the computer are dead. More ...
Multicore Programming
A recent trend in system design is to place multiple computing cores on a single chip. Each core appears as a separate processor to the operating system. We call these multicore or multiprocessor systems. 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 ...
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 ...
First-Come, First-Served 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 first-come, first-served scheduling. More ...
The Many Processes of Silicon Wafer Manufacturing
A silicon wafer is a thin, circular disc used in the manufacture of integrated circuits and semiconductors. The silicon wafer manufacturing process is interesting. More ...
Processor Interrupts
An interrupt is a signal to the processor indicating an event has occurred that needs immediate attention. When an interrupt occurs, the processors normal path of execution is interrupted in order to run a routine to service the interrupt requester. 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 ...
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 ...
Capacitors in AC Circuits
In an AC circuit capacitors exhibit a property similar to resistance called reactance and cause a phase shift between votage and current. The vector sum of resistance and reactance in an AC circuit is called impedance. More ...
