Introduction

+ +

A Verilog implementation of a von Neumann decorrelator, generally called +a conditioner or whitening function. This tiny module consumes entropy +bits and outputs decorrelated bits.

+ +

The Von Neumann decorrelator +consumes pairs of bits and outputs bits based on the pattern in th bit pairs:

+ + + +

In the best case with random bits, the output bitrate will be 1/4. For +heavily biased input bits, the rate will be much slower. When used with +a broken entropy source that is stuck at zero or one, no bits will be +emitted.

+ +

This implementation operates on streams of single bits and creates pairs +internally.

+ +

Status

+ +

Implementation done. Tested in FPGA designs and works.
