This paper identifies the scope for improvement in the execution of baseline kNN join algorithms in a distributed environment. Improvements are suggested and the improved methods are applied in performing kNN joins on R*-Trees. The effectiveness of the proposed improvements have been experimentally verified and presented.
Modified Booth algorithm is most important algorithm for fast multiplier and multiplier take important role in high performance system, reduce power and area optimized is very important in high performance system and DSP system, the focus of this paper is modified booth multiplier algorithm for unsigned Radix-2 and Radix-4 which is a parallel multiplier. It(More)
Power consumption and small area is very important for fabricating DSP system and high performance system, requirement of present scenario computer system is dedicated for very high speed and low power unique multiplier unit for signed and unsigned number therefore in this paper focus on unsigned number by using modified booth multiplier. The unsigned 4 bit(More)
A logic gate is a device that performs a certain Boolean logic operation on one or more logical inputs and produces a single logical output. The logic values are either "true or "false and are represented as 1 and 0, respectively. In other words Logic gates are bistable devices, that is, they may yield one of these two possible stable outputs. The(More)
