Unique Flexible Design

» “From Prototype through Production”: same board can be used for all stages of the development cycle

» Innovative, modular approach, allows hardware design decisions in parallel to application development:

the specific type of DSPs to be used in the final system

the number of DSPs per board needed to achieve the required channel density

the types of DSPs to be integrated on the same board simultaneously
