+vndecorrelator
+==============
+
+A Verilog implementation of a von Neumann decorrelator.
+
+This tiny module consumes pairs of bits and generates decorrelated
+bits. Basically given a sequence of two bits, the decorrelator will:
+
+0, 1: Emit 1
+1, 0: Emit 0
+0, 0: Emit nothing
+1, 1: Emit nothing
+
+The rate of bits emitted is thus at most half of the bitrate on the
+input.
+
+The module is synchronous, but bits may arrive a number of cycles
+between eachother. The module will set the syn_out flag during one cycle
+to signal that the value in data_out is a valid bit.
