Abstract

This paper presents the new approach to a rate increase of multiplication, which is the most commonly used operation in data computation. Multiplications are usually done in multibit Pulse Code Modulation (PCM) format. However, applying this format is connected with doing many time-consuming operations what often causes the increase of the total calculation time. On the other hand, mixed formats which join differential codes with PCM codes can lead to the decrease of code word length and speed-up operation in the data computation. Differential codes can be obtained on the basis of differential kinds of Delta Modulation (DM). Some kinds of DM such as MDPCM (Modified DPCM) and SDPCM (Synthetic DPCM) enable to replace the multiplications with fast shift operations.
