Distributed Median,Alice has an array A, and Bob has an array B. All elements in A and B are distinct. Alice and Bob are interested in finding the median element of their combined arrays.
In this application note we will only refer to the FX1. The
same terminologies and concept is also used in the FX2. The
FX2 has identical FIFO architecture and the same number of
endpoints as the FX1
