What is difference between parallel processing and vector processing?
Parallel processing Parallel processing is the simultaneous processing of the same task on two or moremicroprocessors in order to obtain faster results. The computer resources can include a single computer with multiple processors, or a number of computers connected by a network, or a combination of both. The processors access data through shared memory. Somesupercomputer parallel processing systems have hundreds of thousands of microprocessors.Vector processing"A vector processor, or array processor, is a CPU design wherein the instruction set includes operations that can perform mathematical operations on multiple data elements simultaneously. This is in contrast to a scalar processor, which handles one element at a time using multiple instructions. The vast majority of CPUs are scalar (or close to it). Vector processors were common in the scientific computing area, where they formed the basis of most supercomputers through the 1980s and into the 1990s, but general increases in performance and processor design saw the near-disappearance of the vector processor as a general-purpose CPU.
Compare and contrast the energy processing organelle?
To mostly compare the energy processing organelle, you can compare using size.
Compare and contrast computer and typewriter?
typewriters and word processors are both used to produce writing in a neat,mechanically produced
Classification or types of image processing?
Image Processing classify as three type. (1) Low level image processing (noise removal, image sharpening, contrast enhancement) (2) Mid level image processing (segmentation) (3) High level image processing (analysis based on output of segmentation)
What is meant by ringing artifacts in image processing?
Edges with high contrast that have shadows after compression (like rings when you drop a pebble into a pond).
How do you xxplain vector processing issues.?
A vector processor is a Central Processing Unit design that is able to run mathematical operations on multiple data elements simultaneously. This is in contrast to a scalar processor which handles one element at a time.
What does sonic components mean?
Sonic Components: * sound spectrum * frequency range * equalization * dynamics * sound contrast * mix * panning * effects processing
What are scalar instructions in parallel architecture and computing?
The part of a computer that allows it to function, carrying out the instructions of various programs, is the central processing unit (CPU). The CPU, also called a processor, receives a program's instructions; decodes those instructions, breaking them into individual parts; executes those instructions; and reports the results, writing them back into memory. The format for that processor comes in one of two primary types: vector and scalar. The differencebetween the two is that scalar processors operate on only one data point at a time, whilevector processors operate on an array of data.Scalar processors are the most basic type of processor. These process one item at a time, typically integers or floating point numbers, which are numbers too large or small to be represented by integers. As each instruction is handled sequentially, basic scalar processing can take up some time. Most modern computers use a type of scalar processor.In contrast, vector processors operate on an array of data points. This means that rather than handling each item individually, multiple items that all have the same instruction can be handled at once. This can save time over scalar processing, but also adds complexity to a system, which can slow other functions. Vector processing works best when there is a large amount of data to be processed, groups of which can be handled by one instruction.Vector and scalar processors also differ in their startup times. A vector processor often requires a prolonged startup of the computer because of the multiple tasks being performed.Scalar processors start a computer in a much shorter amount of time, since only single tasks are being executed.The superscalar processor takes elements of each type and combines them for even faster processing. Using instruction-level parallelism, superscalar processing can perform multiple operations at the same time. This allows for the CPU to perform much faster than a basic scalarprocessor, without the additional complexity and other limitations of the vector processor. There can be problems with this type of processor, however, as it must determine which tasks can be performed in parallel and which are dependent on other tasks being completed first.Vector and scalar processors are still used on a daily basis. Some video game consoles, for example, use a combination of both vector and scalar processors. Vector processing is seen to have promise when dealing with multimedia tasks in which one instruction can address the large amount of data required for video and audio.
What is the function of the peripheral protein?
Peripheral membrane proteins are proteins that adhere only temporarily to the biological membrane with which they are associated. These molecules attach to integral membrane proteins, or penetrate the peripheral regions of the lipid bilayer. The regulatory protein subunits of many ion channels and transmembrane receptors, for example, may be defined as peripheral membrane proteins. In contrast to integral membrane proteins, peripheral membrane proteins tend to collect in the water-soluble component, or fraction, of all the proteins extracted during a protein purification procedure. Proteins with GPI anchors are an exception to this rule and can have purification properties similar to those of integral membrane proteins.
What is intergral proteins?
Integral proteins are membrane proteins that are permanently attached to the membrane phospho lipid bilayer.ATPase enzyme is an example for the integral proteins which make ATP. Peripheral proteins in contrast present on the surface of the membrane.
What are brightness and contrast in image processing?
Brightness and contrast represent a way to adjust an image. They come from the display technology, being common controls in all monitors. The color brightness/contrast are similar to the grayscale counterparts, in most cases being applied to all channels (even if from the physical point of view this is wrong - a transformation into HSI with adjustment of the I component would be correct -. For a grayscale image, brightness represents an image adjustment where a constant value is added to all pixel values. The contrast adjustament is a multiplication of the pixel values with a constant. Most of the image processing programs use a different scale, for example from 0 to 10. If you wish to experiment with it, you can do it photoshop, gimp. To apply a brightness/contrast correction to a bunch of images is easier with an image converter like AZImage - see related link.
What are the four major areas of computer operations in digital image processing?
The four major areas of computer operations in digital image processing is contrast enhancement. The second is remove the blur from pictures and smooth out graininess. The third would be magnifying, and rotating an image. Finally the image is compressed for storage.
