Abstract
A parallel processor (110) operates in the LOG domain. A LOG converter (114) receives input data in the NORMAL and converts it to the LOG domain for processing in the parallel processing units PPU-k. Scaling of the input data, is performed in the LOG converter (114) without need for additional multipliers. A constant factor is added to the LOG input data during the LOG conversion process using existing LOG adders already present to perform the LOG conversion. Thus, less total circuitry is needed and the processor can be made more compact, more efficient and less costly.
