Modern Architecture Flashcards
What is pipelining? What are the benefits?
A pipeline where different instructions move through each step like an assembly line. E.g. Time –> | IF | ID | EX | MEM | WB |This improves instruction throughput.
What is computer architecture?
Computer architecture is the design and organization of a computer system including its components and the way they interact to perform tasks.
Explain the concept of pipelining in computer architecture.
Pipelining is a technique where multiple stages of instruction execution are overlapped in a sequential manner to improve the overall throughput of the processor.
What is a CPU pipeline?
A CPU pipeline is a series of processing stages that allow multiple instructions to be executed concurrently. Each stage performs a specific task in the instruction execution process.
How does pipelining improve performance in a CPU?
Pipelining improves performance by allowing different stages of instruction execution to operate concurrently reducing the overall time it takes to execute a sequence of instructions.
What are hazards in CPU pipelining?
Hazards in CPU pipelining are situations that can stall or affect the normal flow of instructions through the pipeline. Common types include data hazards control hazards and structural hazards.
Explain the concept of multicore processors.
Multicore processors have multiple processing cores on a single chip allowing parallel execution of multiple tasks. This design enhances overall system performance by handling multiple threads simultaneously.
What is the advantage of using multicore processors?
The primary advantage of multicore processors is increased processing power and improved performance especially in multitasking scenarios where multiple tasks can be executed in parallel.
How does parallel processing relate to multicore processors?
Parallel processing involves the simultaneous execution of multiple tasks or instructions. Multicore processors enable parallel processing by providing multiple cores that can execute tasks independently.
What is the role of cache memory in computer architecture?
Cache memory is a small high-speed type of volatile computer memory that provides high-speed data access to a processor and stores frequently used computer programs applications and data.
Explain the concept of instruction set architecture (ISA).
Instruction Set Architecture (ISA) defines the set of instructions that a processor can execute. It includes the operations a processor can perform the data types and the register architecture.
