By streamlining the implementation a bit, the LRNG interrupt handler now operates about 130% faster than the existing /dev/random (average of 97 cycles of the existing /dev/random code vs. an average of 42 cycles of the LRNG). This fast operation is the default now due to patch [2]. The conceptual data handling outlined in [3] section 2.2 remains unchanged. Even the addition of health tests applied to the noise source data would still result in a faster interrupt handling code (average of 97 cycles of the existing /dev/random code vs on average 78 cycles of the LRNG).
