Design of the FAT file system significant bits the second (f.e cluster 1). In other words, while the low eight bits of the first cluster in the row are stored in the first byte, the top four bits are stored in the low nibble of the second byte, whereas the low four bits of the subsequent cluster in the row are stored in the high nibble of the second byte and its higher eight bits in the third byte. The FAT16 file system uses 16 bits per FAT entry, thus one entry spans two bytes in little-endian byte order: The FAT32 file system uses 32 bits
Stochastic computing can take the logical AND of the two streams. The probability of a one in the output stream is formula_5. By observing enough output bits and measuring the frequency of ones, it is possible to estimate formula_5 to arbitrary accuracy. The operation above converts a fairly complicated computation (multiplication of formula_3 and formula_4) into a series of very simple operations (evaluation of formula_9) on random bits. More generally speaking, stochastic computing represents numbers as streams of random bits and reconstructs numbers by calculating frequencies. The computations are performed on the streams and translate complicated operations on formula_3 and formula_4 into
