NXP provides Cadence DSP-equipped general-purpose microcontroller i.MX RT 500/600
The i.MX RT 500/600 series provided by NXP is a general-purpose microcontroller equipped with an Arm Cortex M33 equipped with a Cadence DSP.
It enables low power consumption and high performance audio functions to be implemented in IoT applications, wearable devices, and audio devices.
Smart speakers and Bluetooth earphones For audio-focused products such as i.MX RT 685 is best.
Smartwatches, smart glasses, and AI robots For products that require audio and display, i.MX RT 595 is best.
Other devices include the i.MX RT 555, which has reduced DSP functionality, and the i.MX RT 533, which has reduced DSP and GPU functionality.
It also features a PowerQuad DSP Coprocessor and Accelerator, which provides the core's arithmetic operations for math, matrices, filters, and transform functions (e.g. Fast Fourier Transform (FFT)).
Accelerate common DSP calculation tasks and save CPU time.
Please see this document for the differences between i.MX RT 500/600.

Cadence DSP development tools
Cadence Tensilica Xplorer
The DSPs installed in the i.MX RT 500/600 are Cadence's Tensilica Fusion F1 DSP and Tensilica HiFi 4 DSP.
You can use the Cadence Xtensa Xplorer IDE for DSP development. You can download it from the Tensilica Tools site below.
NXP also provides a user guide, which you should also take a look at.

The following materials explain a demo using the library software Xtensa Audio Framework (XAF).
DSP Concepts
DSP Concepts' Audio Weaver is the industry standard development platform for audio.
By introducing this software, audio signal flows can be designed using an intuitive GUI,making the entire design workflow faster and easier, contributing to users' time to market development.
Supports the HiFi 4 DSP on the i.MX RT 685.
Please refer to the on-demand seminars listed below.
