What is Pipelining?

 Pipelining is an arrangement of the CPU’s hardware components to raise the CPU’s general performance. In a pipelined processor, procedures called ‘stages’ are accomplished in parallel, and the execution of more than one line of instruction occurs.


Design of a basic Pipeline

  • In a pipelined processor, a pipeline has two ends, the input end and the output end. Between these ends, there are multiple stages/segments such that the output of one stage is connected to the input of the next stage and each stage performs a specific operation.
  • Interface registers are used to hold the intermediate output between two stages. These interface registers are also called latch or buffer.
  • All the stages in the pipeline along with the interface registers are controlled by a common clock.

What is Artificial Intelligence ?

Image
  Artificial Intelligence  (AI) refers to the simulation of human intelligence in machines that are programmed to think and act like humans. It involves the development of algorithms and computer programs that can perform tasks that typically require human intelligence such as visual perception, speech recognition, decision-making, and language translation "Artificial Intelligence is the study of how to make computers do things at which, at the movement, people are better". ~ Rich and Knight (1991) Types of Artificial Intelligence Artificial Intelligence (AI) is broadly classified into: Types of AI Based on Capabilities Types of AI Based on Functionalities

Cybersecurity in the AI Era: Evolve Faster Than the Threats or Get Left Behind

  AI is changing cybersecurity faster than many defenders realize. Attackers are already using AI to automate reconnaissance, generate sophisticated phishing lures, and exploit vulnerabilities before security teams can react. Meanwhile, defenders are overwhelmed by massive amounts of data and alerts, struggling to process information quickly enough to identify real threats. AI offers a way to level the playing field, but only if security professionals learn to apply it effectively. Organizations are beginning to integrate AI into security workflows, from digital forensics to vulnerability assessments and endpoint detection. AI allows security teams to ingest and analyze more data than ever before, transforming traditional security tools into powerful intelligence engines. AI has already demonstrated its ability to accelerate investigations and uncover unknown attack paths, but many companies are hesitant to fully embrace it. Many AI models are implemented with such velocity that th...

Computer Organization | Instruction Formats (Zero, One, Two and Three Address Instruction)

Image
  Instruction formats refer to the way instructions are encoded and represented in machine language. There are several types of instruction formats, including zero, one, two, and three-address instructions. Each type of instruction format has its own advantages and disadvantages in terms of code size, execution time, and flexibility. Modern computer architectures typically use a combination of these formats to provide a balance between simplicity and power. Different Types of Instruction Fields A computer performs a task based on the instructions provided. Instructions in computers are comprised of groups called  fields . These fields contain different information for computers which are all written in 0s and 1s. Each field has a different significance or meaning, based on which a CPU decides what to perform. The most common fields are: The operation field specifies the operation to be performed, like addition. Address field which contains the location of the operand, i.e., re...
