Control Unit in Computer Organization and Architecture
The Control Unit (CU) is a fundamental component of the central processing unit (CPU) in computer systems. It acts as the “brain within the brain,” orchestrating the execution of instructions by directing the operation of other components such as the Arithmetic Logic Unit (ALU), registers, memory, and input/output devices. The CU does not perform actual…

Pipeline Hazards in Computer Organization and Architecture
Pipeline hazards are challenges that arise in instruction pipelining, potentially reducing the performance gains expected from overlapping instruction execution. These hazards disrupt the smooth flow of instructions through the pipeline, leading to delays or incorrect execution. Understanding and mitigating pipeline hazards is critical for optimizing processor performance in pipelined architectures. Types of Pipeline Hazards Pipeline…
