Abstract

It is at times desired to generate random bit streams in a real-time DSP for the purpose oftesting digital systems. While data that has an equal num- ber of ones and zeroes is easy to produce, a bit stream with a fixed bias is often needed to model a known BER condition. This type of data is useful for exer- cising processes whose performance is effected by the number of bit errors. For practical reasons, it is desired that the bit patterns do not repeat over any realistic time Frame and be computationally efficient.
