STMicroelectronics has announced a DSP library for its ARM Cortex-M3-based STM32 microcontrollers, allowing developers to host signal processing and control functions on the same core.
The DSP library is licence-free, royalty-free and provides a large number of valuable functions coded in C or assembly language. These include a PID controller, Fourier transform functions and a selection of digital filters such as 16-bit FIR, IIR direct-form and IIR canonical-form filters. The functions are comprehensively documented to promote software maintainability and accelerate end-product development.
Taking advantage of the signal-processing capabilities of the ARM Cortex-M3 instruction set, the library functions achieve high execution speeds. Operations such as multiply-accumulate or hardware divide can be executed within only two cycles. Demonstrations running on the STM32F103 Performance Line MCU have performed a complex 256-point 16-bit radix-4 Fast Fourier Transform (FFT) in only 362 μs.
The new libraries can be used with the IAR, Keil and Raisonance tool-chains for the STM32. Developers can take advantage of this for applications such as digital power conversion including solar-energy projects, closed-loop control of switched-mode power supplies, audio and speech processing, and digital image processing.
