Microchip’s EV08Z13A evaluation board features Microchip’s Timberwolf audio processor, capable of running the full family of Timberwolf technology firmware. The EV08Z13A is designed to help developers quickly prototype and demonstrate high-quality audio processing algorithms such as full-duplex stereo echo cancellation, beamforming, noise reduction, dynamic range control, audio event detection etc.,
The EV08Z13A evaluation board can be used to easily demonstrate algorithms for 2-way voice communication, embedded speech recognition, and audio event detection applications by using the Timberwolf Demo Tool software. Once ready for application-specific customization, the EV08Z13A can be configured and tuned with the Microchip MiTuner GUI software.
In the frame of a Space flight application deployment,system partial or full reconfiguration/reprogramming after integration is becoming a stringent requirements. It can allow late bug fixes in a system in the last stages of development and also after launch of the mission. You can also take the benefits of the reprogramming capability for Processing algorithm enhancement/fine tuning after mission deployment and for re-purposing of functioning flight hardware after mission completion. Combining the flexibility of the radiation tolerant FPGA structure and the efficiency of the radiation hardened or radiation tolerant micro-controllers, Microchip can provide Space Applications with the highest level of In-Flight reconfiguration.
With the RTG4 and RT-PolarFire FPGA families, Microchip offers an unrivaled space rated FPGAs portfolio that can be reprogrammed during their flight. Reprogramming of those FPGAs is done thanks to a simple interface that can be managed by a processor/micro-controller. Combined with the SAMRH71F20 Space rated micro-controller that is capable to operate up to 200DMIPS/s, it becomes quite simple to provide a reconfigurable architecture to your Space application. Interconnecting the FPGA and the micro-controller with only a few IOs allows to manage the complete reprogramming process, emulating the JTAG interface and the configuration protocol directly in the micro-controller firmware.
Thanks to the RTG4 and RT-PolarFire FPGAs and the SAMRH71F20, In application reconfiguration is now available for Space flight applications.
Two demonstrations are already available and ready to use, based on standard development kits and Software of-the-shelves.
The main principle of the RT-FPGA reconfiguration is that the micro-controller manages the in-flight programming process of the RT FPGA thanks to the Direct C library that emulates both the JTAG interface of the FPGA and the configuration protocol. The micro-controller manages the up-link via telecommand system to accepts new programming bitstream for the FPGA, stores the bit stream in memory, places FPGA into programming mode, executes Direct C code to initiate transfer of programming bit stream to FPGA, monitors FPGA return to operation and re-initiate programming in case of programming upset.
Microchip's Wi-Fi® Smart Device Enablement Kit is designed to accelerate adding Alexa Voice Control to your existing application, enabling rapid prototyping.
The kit allows you to use an Alexa Smart Speaker or the Alexa App to control the board's GPIO, interrogate its sensors, and change its LED colors. By following our Alexa skill examples, you can create custom Alexa skills to further enhance the operation for your application. For more information please visit the GitHub page HERE.
