摘要: In a digital signal processing unit, addressing apparatus implements multiplicity of modes. The addressing modes include circular buffer memory mode, frame and a sorting mode. To increase the speed address modification, index 561, in presence a positive wrap-around 562, of negative 563 are determined together. Other apparatus determines mode 52 provides control signals for selection correct index. correct index 58 is combined with base address 55 to provide the next new 59.
