The MIMO DSP Platform, announced in 2021, won the hearts of signal processing developers as a native development platform for rapid signal processing. In 2023, DSP island was born, inheriting the genes of the MIMO DSP Platform. The new modular concept not only enables rapid development, but also ensures flexibility in signal processing. We provide the optimal tools for each development stage, such as C++ for developing signal processing core modules and Python and GUI for connecting between blocks. With DSP island, you can develop new signal processing systems that go beyond prototyping and enter a new world.
