Single-chip 2-port adaptors for wave digital filters

In recent years, systolic arrays have been widely used for the implementation of signal processing algorithms. The letter reports on the development of a bit-level 2-port systolic adaptor for wave digital filters (WDFs). The 2-port adaptor can be used for the realisation of WDFs based on the cascade of unit elements and lattice analogue filters. The VLSI design of the adaptor is accomplished using the SOLO 1400 design tool.
