Benchmarks? Lesson 02 Choosing the Right Architecture for Real-Time Signal Processing Designs Leon Adams, Texas Instruments Danger heck who is the author of the recommendation They typically have an Check who is the author of the recommendation. They typically have an not-so-hidden agenda. This article claims that a DSP p as the best choice for essentially all applications. Why? Lesson 02 SP Technolog Concl sion DSP Technology Conclusion Many factors are involved in technology decisions. Performance/power - best known to the academic thers often of equal importance Others often of equal importance Cost Availability Software design support Interoperability Vendor or 3 rd party intellectual product (IP) support roduct roadmap (including legacy components) Product roadmap (including legacy components) Many others Lesson 02 Linear Systems (Review) Review material • What is a linear system? • What are the theoretical underpinnings of linear systems? h t i th l i l l ti th d? • What is the classical solution method? • What are alternative solution methods? . Lesson 02 Linear Systems Fundamentally, discrete-time systems can be partitioned into two broad classes: linear and non-linear . If a system is not linear, then it is non-linear. Linear systems obey the law of superposition (Circuits 1). a a S =? b S b S ? Lesson 02 inear Systems Linear Systems Does the linear equation y[k]=ax[k]+b represent a linear system?
