DMA Controlled I/O The method that is used to transfer information between internal storage and external I/O devices is known as the I/O interface. The […]

Introduction to USART A USART (Universal Synchronous/Asynchronous Receiver/Transmitter) is a microchip that facilitates communication through a computer’s serial port using the RS-232C protocol. USART provides […]

Synchronous and Asynchronous Serial Transmission For Synchronous and Asynchronous Serial Transmission, As we know Serial Transmission data is sent bit by bit, in such a […]

Modes of Parallel transfer When data is sent using parallel data transmission, multiple data bits are transmitted over multiple channels at the same time. This […]

Serial Interfacing Serial interfacing is a communication interface between two digital systems that transmits data as a series of voltage pulses down a wire. A […]

Parallel Interfacing Parallel interfacing provides a multiline data channel in which bits are sent across multiple conductors simultaneously. The bits must stay in synchronization as […]

RISC and CISC architecture The architectural designs of CPU are RISC (Reduced instruction set computing) and CISC (Complex instruction set computing). CISC has the ability […]

Register-based and accumulator based architecture A register-based CPU architecture has one or more general-purpose registers (where “general purpose register” excludes special-purpose registers, like stack pointer […]

Different level of parallelism There are several different levels of parallelism: bit-level, instruction-level, data, and task parallelism. Parallelism has long been employed in high-performance computing, […]

Parallel and Concurrent Systems Parallel and Concurrent Systems are synonyms in many fields; not so in programming, where they are used to describe fundamentally different […]
