Instruction Level Pipelining
What is pipelining? Explain pipelining using 4-segment instruction cycle. What are its advantages?[10]
Pipelining is a technique used in computer architecture to improve CPU performance by overlapping the execution of multiple instructions. Instead of waiting for one instruction to complete all its phases before starting the next, the CPU divides instruction...
Full solved answer →What do you mean by pipelining concept? Discuss various pipeline hazards and their solutions in detail. [5]
Pipelining is a technique used in computer architecture to improve CPU performance by overlapping the execution of multiple instructions. Instead of completing one instruction fully before starting the next, the processor divides instruction execution into ...
Full solved answer →Explain an instruction pipeline with an example. [5]
An instruction pipeline is a technique used to improve CPU performance by overlapping the execution of multiple instructions. Instead of completing one instruction fully before starting the next, the processor divides instruction execution into several segm...
Full solved answer →What are the different types of pipe line hazards? Explain each pipe line hazard with example.[10]
Pipelining is a technique of decomposing a sequential process into suboperations, with each subprocess being executed on a special dedicated segment that operates simultaneously with all other segments. However, certain situations arise during pipelined exe...
Full solved answer →Differentiate between instruction pipeline and an arithmetic pipeline. [5]
An instruction pipeline is a pipeline technique used to execute multiple instructions simultaneously by overlapping the stages of the instruction cycle (fetch, decode, execute, store). It treats the processing of instructions like an assembly line, where ea...
Full solved answer →Flynn's Classification
What do you understand by Flynn's classification? Explain. [5]
Flynn's classification is a taxonomy that categorizes computer architectures into four major groups based on the number of concurrent instruction streams and data streams that a processor can handle simultaneously. - Instruction Stream: The sequence of inst...
Full solved answer →Explain the Flynn's classification of computer architectures with diagrams.[10]
Flynn's classification (proposed by Michael J. Flynn in 1966) is a widely used taxonomy for categorizing computer architectures based on two independent dimensions: 1. Number of Instruction Streams - the sequence of instructions performed by the processor 2...
Full solved answer →Parallel Processing
Draw a three dimensional hypercube and explain with example. [5]
--- A hypercube (also called an n-cube) is a geometric structure used in computer architecture and graph theory to represent interconnection networks. An n-dimensional hypercube has: - 2^n nodes (vertices) - Each node is labeled with an n-bit binary address...
Full solved answer →Explain an inter connection network and its use. [5]
An interconnection network is a programmable system of switches and links that connects a set of processors, memories, and input/output devices in a multiprocessor or parallel computing system. It provides the communication infrastructure that allows data t...

What do you mean by pipeline? Explain with space time diagram for a six segmented pipeline showing the time it takes to process eight tasks.[10]
- Number of pipeline segments: $k = 6$ - Number of tasks to be processed: $n = 8$ (All required numeric values are present.) --- A pipeline is a technique of decomposing a sequential process into sub-operations, with each sub-operation being executed in a d...
Full solved answer →How performance of computer is increased using pipeline? Explain with practical example. [5]
A pipeline is a technique where multiple instruction phases are overlapped in execution to improve the throughput of a computer. Instead of completing one instruction fully before starting the next, different stages of different instructions are executed si...
