Sequential addressing is one of the essential power-consuming parts of digital signal processing (DSP), which is mainly used for sequential memory and coefficient selection. The use of sequential addressing is not only widespread, but also particularly important in a wide variety of DSP applications as most of the computation process proceeds in a sequential manner. Therefore, by reducing both the power of the sequential memory addressing hardware and accesses within the DSP system, the overall power consumption of the system will be effectively reduced. A novel scalable low power multi-segment one-hot all-sequential addressing architecture (MSML-OHA) is presented. This architecture, implemented in 0.18 μm CMOS technology, reduces power dissipation by more than 20% compared to conventional counter-decoder architecture.
