Abstract :
Parallel algorithms on barrel shifter computers for a broad class of 1-D and 2-D signal operators are presented in this paper. Running max/min selection filter, moving average filter and sorting, which can be used in order statistics filtering, are examined. The proposed algorithms require a significantly smaller number of comparisons/computations per output point than the conventional ones. They are suitable to be implemented on barrel shifter computer topologies
