Binary-coded decimal Binary-coded decimal In computing and electronic systems, binary-coded decimal (BCD) is a class of binary encodings of decimal numbers where each decimal digit is represented by a fixed number of bits, usually four or eight. Special bit patterns are sometimes used for a sign or for other indications (e.g., error or overflow). In byte-oriented systems (i.e. most modern computers), the term "unpacked" BCD usually implies a full byte for each digit (often including a sign), whereas "packed" BCD typically encodes two decimal digits within a single byte by taking advantage of the fact that four bits are enough to represent
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
