High speed data compactor
An apparatus for non-destructively compressing data in a stream of N-bit data words from a source of informational and non-informational data words, is described comprised of: comparison means coupled to the data source for comparison testing N-bit data words in the data stream against a predetermined N-bit binary threshold value; a counter means coupled to the comparison means for forming a count word of N binary digits; first flag bit means coupled to the comparison means and the counter means for forming a first (N + 1) bit digital word which included a first valued binary flag digit appended to such of the N bit data words from the data source exceeding the threshold value; second flag bit means coupled to the comparison means for forming a second (N + 1) bit digital word; and means coupled to the first flag bit means and the second flag bit means for selectively transmitting to a data processing system either the first N + 1 bit word or the second N + 1 bit word.
