On the interaction between DSP-algorithms and VLSI-architecture

The interaction between DSP (digital signal processing) algorithms and VLSI architecture is addressed, and it is shown at which levels architecture analysis has to be undertaken and at which levels new possibilities can be exploited. It is noted that the new possibilities of implementing algorithms and even complex systems on dedicated chips lead to the necessity of undertaking a careful analysis of architectures, not only at the algorithmic and the word level but, with increasing complexity of the chip, also down to the bit level. This allows a maximum of regularity to be extracted for the design of basic building blocks which are then used to construct the chip, so that the stated design conditions are optimally met
