SIMD (Single Instruction Multiple Data) is a computer science method of combining multiple operations into a single computer instruction. The total number of operations combined is normally a factor of the power of two. The employment of SIMD results in significant savings in speed for algorithms designed to work in parallel. The technology is used on IA-32 and PowerPC architectures, and is referred to as AltiVec on the PowerPC and MMX (MultiMedia eXtensions) on IA-32 machines. SIMD results in significant gains when used for image processing, 3G graphics, scientific calculations, Read More

It requires n-1 passes to sort an array. In each pass every element a[i] is compared with a[i+1], for i=0 to (n-k-1), where k is the pass number and if they are out of order i.e. if a[i]>a[i+1], they are swapped. This will cause the largest element to move up or bubble up. Thus after the end of the first pass the largest element in the array will be placed in the last or nth position and on the next pass, the next largest element will be placed at position Read More

The call by reference uses a different mechanism. In place of passing value to the function, which is called, a reference to the original variable is passed. A reference is an alias for the predefined variable. That is, the value of that variable can be accessed by using any of the two: the original or the reference variable name. When a function is called by reference, then the formal parameters become reference to the actual parameters in the calling function. This means that, in call by reference method, the called Read More
