A neural processing unit (NPU) is a specialized type of microprocessor designed to accelerate the performance of artificial neural networks (ANNs) and machine learning algorithms. These chips have been developed with the goal of accelerating the training and inference processes…
What is a Digital Signal Processor (DSP)
DSP stands for Digital Signal Processor. It is a specialized microprocessor designed to perform digital signal processing operations on real-world signals like sound, video, and sensor data. DSPs are optimized for handling numerical calculations and are used in a variety…
What is a Hardware Accelerator
A hardware accelerator is a specialized processor that is designed to perform specific tasks more efficiently than a general-purpose processor. Hardware accelerators are often used to speed up tasks that are computationally intensive, such as graphics rendering, machine learning, and…
What is a GPU? A Specialized Graphics Processor
A GPU, or Graphics Processing Unit, is a specialized type of processor designed to handle complex mathematical and graphical computations. Unlike the CPU, which is optimized for general-purpose computing, the GPU is designed specifically to accelerate graphics-intensive tasks, such as…
What is a CPU – The Brain of your Computer
A CPU, or Central Processing Unit, is the primary component of a computer that performs most of the processing tasks. It is often referred to as the “brain” of the computer, as it controls and executes instructions that are stored…
Logic Levels in Digital Circuits
In digital systems, any signal value is represented in binary form (either logic ‘0’ state or logic ‘1’ state). To represent these two logic states, two different levels of voltage or two different levels of current are considered. Here, we…
Hamming Codes
Hamming Code is yet another error detection and correction code. In this code, the parity bits are added to increase the Hamming distance between the valid code words. Here, the parity bits are arranged in a way that different error…
What are Code Words in case of Error Detection and Correction
A system that uses error-detecting code generates, transmits, and stores data in the form of code words. So, the correct data must be a valid code word. It is expected that the presence of an error in a data bit…
Hamming Distance
Hamming distance between two bit-strings of equal length is the number of bit positions at which they are different. In other words, Hamming distance is the number of mismatches at the same bit position between two same-length words. For example:…
Parity Code for Error Detection
One of the most common ways to achieve error detection is by means of parity code. A parity code is generated by adding an extra parity bit (information redundancy) to the string of data bits. There are two types of…
