Byte of the 8080 and the 8086, used in early personal computers, could also perform a small number of operations on the four-bit pairs in a byte, such as the decimal-add-adjust (DAA) instruction. A four-bit quantity is often called a nibble, also "nybble", which is conveniently represented by a single hexadecimal digit. The term "octet" is used to unambiguously specify a size of eight bits. It is used extensively in protocol definitions. Historically, the term "octad" or "octade" was used to denote eight bits as well at least in Western Europe; however, this usage is no longer common. The exact origin
Stochastic computing computing paradigm. Further information can be found in the referenced book by Mars and Poppelbaum. "Bundle Processing" involves sending a fixed number of bits instead of a stream. One of the advantages of this approach is that the precision is improved. To see why, suppose we transmit formula_26 bits. In regular stochastic computing, we can represent a precision of roughly formula_27 different values, because of the variance of the estimate. In bundle processing, we can represent a precision of formula_28. However, bundle processing retains the same robustness to error of regular stochastic processing. "Ergodic Processing" involves sending a stream of
