Technical Consulting and Contract
Design Capabilities
Our experience covers:
1. Design of a new system including waveforms, transceivers
and networks,
2 Standards based implementations,
3. Numerous implementation targets - ASICs, SOCs, FPGAs and
DSPs,
4. Consumer electronics semiconductor algorithms,
5. Military communications systems.
We tailor our design and verification methods to fit the
specific needs of the project at hand. Specific expertise include the following
areas.
