The Shift-and-Add (SAA) technique is a simple mathematical operation developed to reconstruct, at high spatial resolution, atmospherically degraded solar images obtained from stellar speckle interferometry systems. This method shifts and assembles individual degraded short-exposure images into a single ...
The IEEE 754 standard presents two different floating point formats, Binary interchange format and Decimal interchange format. This paper presents a single precision floating point multiplier based on shift and add algorithm that supports the IEEE 754 binary interchange format.. 展开 ...
This variant of the shift-and-add algorithm originally developed by Lynds et al. [Astrophys. J. 207, 174 (1976)] utilizes a weighted impulse distribution of speckle positions to extract an average speckle for a data set. This is done by means of a weighted deconvolution procedure, similar ...
Shift-and-add multiplication is similar to the multiplication performed by pa-per and pencil. This method adds the multiplicand X to itself Y times, where Y de-notes the multiplier. To multiply two numbers by paper and pencil, the algorithm is to take the digits of the multiplier one at ...
1.Furthermore,the improved algorithm achieves the shift-acceleration of patterns and flexibly controls the step length.该算法通过对模式的移位加速和移动步长的灵活控制,使平均移动步长得到很大提高。 4)Extra displacement附加位移 5)shifter-adder移位相加 1.The operating mechanisms of some multipliers such as...
What is the most efficient way of doing this? And if this was being done to each row in a matrix, is there a more efficient way then doing: matrix = [shift(row)forrowinmatrix] Also, if I was to shift the matrix in the other three directions (apart from right), are there more eff...

We present a method for implementing high speed finite impulse response (FIR) filters using just registered adders and hardwired shifts. We extensively use a modified common subexpression elimination algorithm to reduce the number of adders. We target our optimizations to Xilinx Virtex II devices wher...
