<p>Instruction Level Parallel Processing (Pipelining) involves making a single CPU perform several instructions at the same time by dividing the program into instructions and executing them through five main steps: Fetch, Decode, Fetch operand, Execute, and Store Results. This allows for partial overlapping of the execution of two instructions, providing improved performance.</p> Signup and view all the answers

<p>The two types of parallel processing discussed are Instruction Level Parallel Processing (Pipelining) and Processor Level Parallel Processing. The former involves making a single CPU perform several instructions at the same time by dividing the program into instructions and executing them through five main steps, while the latter involves using multiple CPUs to solve a single problem.</p> Signup and view all the answers

<p>The primary benefit of pipeline execution in processors is the partial overlapping of the execution of two instructions, allowing for improved performance and efficiency in CPU operation.</p> Signup and view all the answers

<p>Superscalar architecture refers to the use of multiple pipelines or a single pipeline with multiple execution units, allowing the processing of more than one instruction at a time. This architecture is significant in parallel processing as it enhances the performance of CPUs by enabling them to execute multiple instructions concurrently.</p> Signup and view all the answers

<p>In sequential execution, no instruction can start executing until the previous instruction is completed, while in pipeline execution, there is partial overlapping of the execution of two instructions, allowing for improved performance and efficiency.</p> Signup and view all the answers
