The Renesas RX MCU team has been presenting proposals to make the use of DSP easier.
- Implementing DSP at a low cost
- Visualizing DSP operation
- Proposals for the use of DSP with RX MCUs
DSP has been implemented in various fields such as home electric appliances, industry, and health/medical care. In addition, the range of use is getting wider due to ongoing IoT/Cloud. On the other hand, DSP is often considered as difficult and high cost, so people apparently hesitate to start the development of a system using DSP.
Then, as an example of the use of a DSP to be implemented at low cost, we have released the sample program of the FIR filter using the latest low-end RX140 RX family MCU.
- Inputs analog signals directly to RX140 (Sampling frequency: around 10kHz)
- Makes a judgment of the frequency band of the input signal by three FIR filters.
- Displays the judgment result with LEDs on the evaluation board.
- Visualizes input/output signals to/from the FIR filter using the waveform display function of Integrated Development Environment e2 studio.
The sample program is designed to leverage the strengths of the RX140.
- Mounts RXv2 core that can perform high-speed DSP operation
- Utilizes DSP Library for RX Family that maximizes the performance of RXv1/v2/v3 CPU
- Realizes the system with a single chip (A/D conversion, DSP, HMI)
By referring to this sample program, you can develop the system with DSP application in a short period. The sample program is an example of a simple implementation of the FIR filters, and digital filters can be applied for various applications. (Analyzing sensing data, improving voice recognition accuracy, enhancing power supply quality, etc.)
Please consider developing a DSP system application using the latest RX140 MCU.
