A full-day BDTI seminar
UNDER DEVELOPMENT
Contents
This class will provide an introduction to DSP
processor architectures and features, and
is based on BDTI’s popular introductory textbook
of the same name.

Conclusion
Berkeley Design Technology, Inc (BDTI) is a technical services
and software company focused on DSP technology. BDTI is
well-known for developing the only vendor-independent set of
DSP benchmarks, the BDTI Benchmarks™, which it has
implemented on nearly every processor used in DSP today. BDTI
provides DSP software development and optimization services,
published reports on DSP technology, and DSP technical
advisory services.
