ABSTRACT:
A high-speed universal scaler operates in real time, accepting as an input an N-bit binary data word which is to be scaled (multiplied) by a scale factor specified in units per bit. The input data word is divided into M-bit sections which are provided (together with a count value indicating the position of the M-bit section within the input data word and a scale indicator value specifying which of a plurality of programmed scale factors values is to be used) sequentially as scaling addresses specifying binary coded decimal scale data in a scale memory. The sequential outputs of the scale memory in response to the scaling addresses are summed. When the sequence of addresses has been completed and all of the sequential memory outputs have been summed, the resulting sum will be a scaled binary coded decimal value equivalent to the input data word.
