Byte addressing might still need to access 8-bit data over its 64-bit address line, and have the data returned in the bottom 8 bits of its longer data line. Byte addressable memory refers to architectures where data can be accessed and addressed in units that are narrower than the bus. An eight-bit processor like the Intel 8008 addresses eight bits, but as this is the full width of the bus, this is regarded as word-addressable. The 386SX, which addresses memory in 8-bit units but can fetch and store it 16 bits at a time, is termed byte-addressable. Bytes have not always meant
Stochastic computing Stochastic computing Stochastic computing is a collection of techniques that represent continuous values by streams of random bits. Complex computations can then be computed by simple bit-wise operations on the streams. Stochastic computing is distinct from the study of randomized algorithms. Suppose that formula_1 is given, and we wish to compute formula_2. Stochastic computing performs this operation using probability instead of arithmetic. Specifically, suppose that there are two random, independent bit streams called "stochastic number"s (i.e. Bernoulli processes), where the probability of a one in the first stream is formula_3, and the probability in the second stream is formula_4. We
