Let's Program the Transistors
What is a DSP? A DSP is optimized for handling numerical calculations and manipulating signals in the digital domain. It typically consists of an Arithmetic Logic Unit (ALU), a multiplier-accumulator unit, and a program memory unit. The ALU performs basic arithmetic and logical operations on the input signals, while the multiplier-accumulator unit performs more complex…
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 cryptography. Hardware accelerators are becoming increasingly popular in modern computing systems because they can improve…
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 3D rendering, video encoding, and scientific simulations. The GPU consists of thousands of small processing…

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 in memory. The CPU is responsible for performing arithmetic and logical operations, managing the flow…
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 will consider voltage for understanding. You can also consider current in the same way. If…
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 bits produce different error results. This enables the Hamming Code to both detect and localize…
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 stream would make it a non code word, and thereby it would be easy to…

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: Consider two 3-bit code words, 000 and 001. Here, the Hamming distance is 1, as…
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 parity, such as even parity and odd parity. A given system operates with either even…
Data errors in a digital system can happen due to faults in the transceiver system or noise during the transmission. Such errors need to be detected and corrected, as digital systems are sensitive to such errors. The presence of data errors beyond a threshold can lead to catastrophic situations if not taken care of immediately….
