The TMS320C64x+™ DSP System Integration Workshop using DSP/BIOS has been designed to use the latest hardware and software development tools available from Texas Instruments. In addition, this workshop builds around the concepts required to easily author simple DSP solutions and how to easily adapt them into increasingly more complex systems as system requirements evolve.
This workshop is not intended to be platform specific. While the labs were written on the 6437, the concepts and API apply to all TI DSP platforms. In fact, code written in the manner shown in this workshop can be easily adapted from one TI DSP processor to another.
Each of the first 10 chapters of the workshop include one or more 'hands on' lab sessions, intended to allow the attendee to 'try out' the concepts covered and obtain confidence in their ability to author code with the TI tools. Most of the labs adapt prior labs to new solutions, in the same manner as would be done in real life, rather than via 'fill in the blanks' or other non-realistic simulations of actual DSP system authoring.

Who should attend
This workshop is designed for engineers who need to develop or sharpen their design and development skills in real-time software design using Code Composer Studio and DSP/BIOS.
Course Prerequisites
Familiarity with C programming will be very helpful, as almost all the code present in the class is C based. Experience in writing code in C is optimal, but even those able to barely read and follow simple C coding examples should not be overly challenged.
Since this class does not presume a particular TI DSP platform, no prior experience with any particular DSP hardware is required. However, users who will develop on a particular platform may want to consider attending one of the platform specific workshops available from TI to round out their knowledge before beginning their design.
