For improving the efficiency of a program, it is important to reduce stalls caused by memory access. Traditional programs usually spend much time on memory stalls when accessing lower-level memory, and so do Java programs. In order to reduce memory stall time, prefetching is a feasible solution. We observed some obvious properties of array access so that we could prefetch array data by taking advantage...
A pseudorandom function is a function that cannot be efficiently distinguished from a truly random function. The first construction of pseudorandom functions was introduced by Goldreich, Goldwasser, and Micali (GGM-construction). In this paper, we propose a variant of the GGM-construction and compare its performance with the original construction. We show that a 4-ary-tree variant construction can...
