Also, adiabatic techniques seem to only be suited to very low speed circuits: the comparison of carry look-ahead adders using adiabatic logic and standard CMOS in [54] found that the adiabatic techniques only gave an advantage at operating speeds of below 3MHz, and the clocked power supply generator consumed a large amount of power which was not considered in the comparison. An approximation to adiabatic operation, without the need for the complex pulsed supply generators, can be obtained using multiple supply voltages switched across the load to approximate a ramped supply.

Another method for avoiding carry propagation problems is to use a residue number system [71]. In these number systems, a number is represented by its remainder modulo for a number of different relatively prime bases. Addition is performed by simply taking the sum of each pair of remainders; with multiplication being a trivial extension to this. However, there is no way of directly determining the sign of a number in residue form, which means that comparison, and hence division, is difficult [72].

It can be seen that the number of multiply and multiply accumulate operations far exceeds the number of simple additions or comparisons required. The processing load is dominated by the calculation of the parameters for the long-term prediction filter (LTP analysis), due to the large number of autocorrelations that need to be calculated to find the optimal lag value. 3: Computation load of GSM full-rate speech coding sections Half-rate and enhanced full-rate coding Half-rate speech transcoding attempts to provide the same perceptual quality as the fullrate transcoding but with half the number of bits, as the name suggests.
