Digital Signal Processing of sounds and images are using many digital filters which conputes the summation of multiplications between a sequence of constats and a time sequence of an input.
In this manuscript, a memory based design method for such constant multiplication is described.
In the design, the trade-off between the size of a memory and that of the logic is considered, and its speed and power consumption is optimized.
The read power of a memory is independent with the output read from the memory and a memory can encapsulate the toggles of logic gates in gate-based designs.
By separating an input into several parts and designing such separated small multipliers using a memory, the memory size can be reduced drastically.
The proposed constant multiplier has been implemented on ASIC, and shows the power reduction compared with gate-level design. |
