SIMD (single instruction, multiple data) describes multiple processing elements that work on the dame operation on multiple data points. MIMD (multiple instruction, multiple data) is the number of processors that function independently.

What is different between SIMD multiprocessing and MIMD multiprocessing?
SIMD DefinedThe SIMD architecture performs an identical action simultaneously on multiple data pieces. This single action can include retrieving, calculating or storing information. An example is retrieving a lot of different files at the same time. Processors with local memory containing different data execute the same instruction in a synchronized fashion, with inter-processor communication for shift allocation.MIMD DefinedThe MIMD architecture performs multiple different actions simultaneously on multiple data pieces. An example is the performance of various mathematical calculations such as addition and multiplication simultaneously in order to solve a complex math problem with many separate components. MIMD computing may or may not be synchronized and is increasing more commonly than SIMD computing.

What is the difference between parallel computing and parallel processing?
Parallel processsing ranges from instruction-level parallelism e.g. superscalar and VLIW to message-passing MIMD also called multicomputer, and also includes SIMD e.g. vector and array processing. Multiprocessing is specifically task parallelism, and is by definition shared-memory MIMD with multiple processor cores, sometimes multiple sockets.

What is the requirement in MIMD?
MIMD (Multiple Instruction, Multiple Data) requires that multiple processors or computing cores concurrently execute multiple instructions on multiple sets of data. This architecture allows for parallel processing of independent tasks, improving overall system efficiency and performance. MIMD systems can be heterogeneous (different processors executing different instructions) or homogeneous (same processors executing the same instructions).
What is flynn's taxonomy of parallel architecture?
Flynn's taxonomy is used to categorize computer architectures. Considers the number of processors and the number of data paths incorporated into an architecture. The fours combinations of processors and data path are: SISD( Single instruction, single data stream) MISD( Multiple instructions, single data stream) SIMD (Single instructions, multiple data streams) MIMD( Multiple instructions, multiple data streams)
Is SSe3 polar?
Yes, SSE3 (Streaming SIMD Extensions 3) is a set of SIMD (single instruction, multiple data) instructions for x86-based microprocessors and is not inherently polar or nonpolar as it is a technology standard for improving CPU performance in certain types of calculations.
What is the Flynn's Classification with examples?
First of all as we know the CPU comprises of The Registers,The ALU Unit and the Control Unit.Processing of the data is done in CPU Registers (an area or a memory where processing takes place). M.J.Flynn suggested these architectures for enhancing the computational speed of the computer: 1. Single Instruction Single Data (SISD): Single instruction is performed on a single set of data in a sequential form.Most of our computers today are based on this architecture.Von Neumann fits into this category.Data is executed in a sequential fashion (one by one). 2. Single Instruction Multiple Data (SIMD): Single Instruction is performed on multiple data.A good example is the 'For' loop statement.Over here instruction is the same but the data stream is different. 3. Multiple Instruction Single Data (MISD): Over here N no. of processors are working on different set of instruction on the same set of data.There is no commercial computer of this kind also these are used in Space Shuttle controlling computer (all the buttons you must have noticed in the control center). 4. Multiple Instruction Multiple Data (MIMD): Over here there is an interaction of N no. of processors on a same data stream shared by all processors.Now over here if you have noticed a lot of computers connected to each other and when they perform a task on the same data (data is then shared).If the processing is high it is called Tightly Coupled and Loosely Coupled vice-versa.Most Multiprocessor fit into this category.

Is a process that allows the CPU to receive a single instruction and then execute it on multiple pieces of data rather than receiving the same instruction each time each piece of data is received?
"SIMD, which stands for 'single instruction, multiple data,' is a process that allows the CPU to receive a single instruction and then execute it on multiple pieces of data rather than receiving the same instruction each time each piece of data is received."(Pg. 434, A+ Guide to Managing and Maintaining Your PC)
