System-level design and analysis of an embedded audio signal processing application

In this report, a design is proposed for an embedded system that implements an audio beamforming application. This design provides the key considerations for both the analog front-end, and the digital signal processing that would be included on-chip. The analog portion of the design implements a multi-order delta-sigma ADC, and the digital portion of the design implements a digital decimation filter and a beamforming filter. The objective of the project is to develop a system that could be used in a real-world implementation, with design decisions which attempt to account for system-wide specifications, rather than focusing on block-level performance alone.
