As signal processing becomes ubiquitous in consumer products, the number and breadth of processor choices for system designers has expanded rapidly. In this presentation, Jeff surveys the latest design trends in processors for DSP: conventional DSP architectures, enhanced conventional architectures, VLIW (very long instruction word) architectures, superscalar architectures, and hybrid DSP/general-purpose architectures. Jeff will identify key technical features of these approaches and highlight their comparative advantages and disadvantages.

Jeff will then discuss how the DSP performance of these different architectures can be fairly measured, illustrated by quantitative comparisons based on BDTI's DSP benchmarks.
