Product Design: PD6 - How to Leverage DSP for Product GreatnessPresenter:
Denis Labrecque, Analog Devices - San Jose, CA, USA
How to deal with the “more” law. While many are familiar with Moore's Law of computing, those of us in Pro Audio are also painfully aware of the “more” law—designing todays' DSP based products require “more”—more performance, more precision, more complex processes, more channels, more power efficiency, more connectivity etc. This tutorial will explore the design considerations, decisions and trade-offs necessary to develop modern audio systems with advanced DSP capabilities. Overall design methodology discussed will include: fixed vs. floating point processing, internal vs. external memory, how requirements change for low power applications, Ethernet/USB connectivity, and peripheral (I/O) selection. In addition, this tutorial will touch on software tools and modules available for the creation of DSP based products. Specific examples will include system block diagrams of SHARC, Blackfin, and SigmaDSP processors.
