In computing, a vector processor or array processor is a central processing unit (CPU) that implements an instruction set where its instructions are designed to operate efficiently and effectively on large one-dimensional arrays of data called vectors.

Feb 14, 2023 · Vector Processors are designed to process multiple data elements in parallel, while Scalar Processors process one data element at a time. Vector Processors can be more efficient, as they can complete a given task with fewer instructions than a Scalar Processor.

An attached array processor is a processor which is attached to a general purpose computer and its purpose is to enhance and improve the performance of that computer in numerical computational tasks. It achieves high performance by means of …

Array processor: Instruction operates on multiple data elements at the same time. Vector processor: Instruction operates on multiple data elements in consecutive time steps. 4. Array vs. Vector Processors. 5.

• Data parallelism: vector and array processing • Control parallelism: parallel and distributed processing Feb. 2011 Computer Architecture, Advanced Architectures Slide 4

In parallel vector processing, more than two results are generated per clock cycle. The parallel vector operations are automatically started under the following two circumstances − When successive vector instructions facilitate different functional units and multiple vector registers.

Vector parallelism is a hardware mechanism that implements parallel computation using the same flow of control on multiple data elements. It supports regular parallelism and can also be applied to irregular parallelism with limitations.

Parallel processors are processors with many near-independent CPUs which collaborate on a single task. Vector Processors: why? these may be operations directly on vectors, or matrix operations. They arise commonly in scientific and engineering calculations.

• Load Imbalance: Parallel tasks may have different lengths – Due to imperfect parallelization or microarchitectural effects – Reduces speedup in parallel portion • Resource Contention: Parallel tasks can share hardware resources, delaying each other – Replicating all resources (e.g., memory) expensive

Vector processing is the arithmetic or logical computation applied on vectors whereas in scalar processing only one data item or a pair of data items is processed. Parallel architectures have also been developed based on associative memory organizations.
