The design automation of the memory-based VLSI architectures for FIR filters is investigated. This paper intends to give a thorough discussion about the design space and schemes for this subject. The discussed topics include the conditions leading to efficient memory replacement, the formulation space of FIR filters, the considerations in architecture design, and the methods to evaluate architectures. With the research results of these topics, we present a parameterized memory-based architecture and the hardware-speed evaluation formulae. This architecture is characterized by three parameters into which various memory-based architectures can be generated by substituting different values. The presented formulae are formulated as functions of the three parameters and implementation technology. Using the evaluation formulae and through the parameterized architecture, an area-minimized architecture can be synthesized under a speed specification. Based on these results, we develop an automatic synthesis tool with an illustrating example.
