What is a Neural Processing Unit (NPU)

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…

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…

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…
