Application Note 221

Using CMSIS-DSP Algorithms with RTX

This Application Note describes the development of a digital filter for an analog input signal using the CMSIS-DSP Library and the RTX-RTOS. The application, designed for an NXP LPC1768 device, can be tested with the µVision Simulator and the Logic Analyzer.

The CMSIS-DSP Library offers a common set of DSP algorithms. Due to the CMSIS layer, the application can be ported easily to other Cortex-M3 or Cortex-M4 processor-based devices. Developers can focus on the application design and requirements, without needing to implement their own, basic DSP algorithms.
