An Efficient Design of Memory-Based Realization of FIR Digital Filter
In the last two decades, many efficient algorithms and architectures have been introduced for the design of low complexity bit-parallel Multiple Constant Multiplications (MCM) operation which dominates the complexity of many digital signal processing systems. On the other hand, little attention has been given to the digit-serial MCM design that offers alternative low complexity MCM operations albeit at the cost of an increased delay. In this paper, the authors address the problem of optimizing the gate-level area in digit-serial MCM designs and introduce high level synthesis algorithms, design architectures, and a computer aided design tool.
