Abstract

Many curricula include separate classes in both digital signal processing (DSP) theory and very high-speed integrated circuit hardware description language (VHDL) modeling; however, there are few opportunities given to students to combine these two skills into a working knowledge of DSP hardware design. A pedagogical framework has been developed whereby students can leverage their previous knowledge of DSP theory and VHDL hardware design techniques to design, simulate, synthesize, and test digital signal processing systems. The synthesized hardware is implemented on field-programmable gate arrays (FPGAs), which provide a fast and cost-effective way of prototyping hardware systems in a laboratory environment. This framework allows students to expand their previous knowledge into a more complete understanding of the entire design process from specification and simulation through synthesis and verification. Students are exposed to different aspects of signal processing design, including finite precision, parallel implementation, and implementation cost tradeoffs.
