Title: Random number generator bit string filter
Inventor: HENRY G GLENN
IPC: G06F9/30
Filed: 2003-04-18
Abstract: A filtering apparatus in a hardware random number generator that prevents the random number generator (RNG) from outputting a contiguous string of zeros or ones longer than a specified length. The maximum length is programmable in the apparatus. The apparatus includes a counter that keeps a current count of contiguous zero bits in a series of bytes generated by the RNG. An adder generates a sum of the current zero bit count and the number of leading zeros in the next byte generated. If the sum exceeds the maximum length, then the filter throws out the byte rather than accumulating it. Otherwise, if the byte contains all zeros, the counter is updated with the sum; or if the byte contains trailing zeros, the counter is updated with the number of trailing zeros; otherwise the counter is cleared. The apparatus does the same for contiguous one bits.
