A new DSP Library has been developed by Renesas Electronics that simplifies the use of the company’s RX600 and RX200 series of microcontrollers (MCUs).
The library enables access to debugged functions that allow faster implementation of many of the numerical, filter and transform operations needed in a variety of consumer and industrial applications, including those for medical, building automation, industrial automation, sensing and audio.
The library features more than 300 functions and an intuitive application programming interface (API). It integrates several functions that can help to reduce development time. For example, instead of writing the filter code from scratch, developers can select one of the filter codes from the fully optimised and debugged DSP Library, freeing up time and resources to work on other tasks, such as fine tuning the filter’s response to meet system requirements. Since it is not necessary to have to do any debug or performance optimisation, development time can be reduced significantly.
The library supports rich data types, including 16-bit fixed point, complex 16-bit fixed point, 32-bit fixed point, complex 32-bit fixed point, 32-bit floating point, and complex 32-bit floating point, and offers fine grain options such as scaling options for the Fast Fourier Transform (FFT).
The DSP Library can be downloaded free of charge from the company’s website. The current library supports the High-Performance Embedded Workshop (HEW) and the iits RXC compiler.
Future versions of the library will also add support for GCC, IAR, and e2studio tool chains.
