Abstract
A number of data movement algorithms for the two-dimensional reconfigurable mesh are presented. These include computing the prefix sum of a binary sequence and computing the prefix maxima of a sequence of real numbers. These algorithms lead to a fast algorithm to sort a sequence of n reals in O(log n/log m) time on a reconfigurable mesh of size mn*n with 3>
