1. A computer-implemented process for processing signals in a byte-based computer system, comprising the steps of: (a) providing an initial value of a byte pointer; (b) providing an initial value of a bit pointer; (c) processing a first signal using the byte pointer and the bit pointer, wherein the first signal represents data corresponding to physical subject matter; (d) updating the bit pointer based on the processing of the first signal; and (e) updating the byte pointer using the updated bit pointer as an index to a lookup table.
