DSP Libraries
Our team has been developing signal processing libraries for more than 10 years and has excellent expertise in a variety of fields - from radio communications to neuroprocessing. We have worked with all popular commercially available processors, such as TI C55, C64x, C66x; ADI Shark, Blackfin, 21xx; Motorola and others.
We offer services for adapting existing libraries to your hardware and software environment:
- modification for special requirements
- adaptation to an application or a special DSP core
- API migration from one core to another
- reference code, test tools for simulation models run without using processor simulators
- datasets for functional validation and performance verification on your core
Our libraries are usually supplied as part of the IDE (development environment) in source codes and allows you to quickly and easily master a new processor and learn how to write productive software and optimization methods.
