SIMD Defined
- The 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 Defined
- The 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 difference between SIMD and MIMD?
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 has the author Matthew D Levin written?
Matthew D. Levin has written: 'Parallel algorithms for SIMD and MIMD computers'
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)
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 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.
Static versus dynamic network in SIMD interconnection network?
Static- Links between two processor are passive & dedicated buses cannot be reconfigured for direct connection to other processor.Dynamic- It can be reconfigured by setting the n/w active switching element.with different classes i.e single stage & multistage.
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)
What does the acronym SSE stand for?
There are many different things that use the abbreviation SSE. In computing, it can stand for Streaming SIMD Extensions, server-sent events, or simple sharing extensions. It can also be used for supply-side economics and is also an energy company in the UK.
What are multi vector and SIMD computers?
(Single instruction, Multiple Data) A process that allows the CPU to execute a single instruction simultaneously on multiple peices of data, rather than by repetitive looping.
What is array processor and what is the role of attached array processor?
aray processor is a processor that performs computations on large arrays of data. It is of two types: (1) attached array processor. (2)SIMD array processor.
What does MMX stand for?
it stands for Multimedia extension. MMX is a technology by using which a computer can accept an input or give an output in the form of text, image or sound. MMX enabled microprocessors employ SIMD (Single Instruction Multiple Data) technique of data processing.
