Here is a single instruction one for the ARM:
RSB R0,R0,R0,ROR #21
The analysis of 40 000 000 bytes worth of the least significant byte:
- Entropy = 7.999 985 bits per byte.
- Optimum compression would reduce the size of this 40 000 000 byte file by 0 percent.
- Chi square distribution for 40 000 000 samples is 810.80, and randomly would exceed this value 0.01 percent of the times.
- Arithmetic mean value of data bytes is 127.4731 (127.5 = random).
- Monte Carlo value for Pi is 3.143 189 714 (error 0.05 percent).
- Serial correlation coefficient is -0.000 131 (totally uncorrelated = 0.0).
