Echoes is a PULPissimo based chip, and uses the new CV32E40P from OpenHW group as its core not the original RI5CY core. The chip has 512 KiB memory, a range of peripherals and an FFT accelerator
The name and the logo of the chip are inspired by Pink Floyd. Davide Rossi is a great fan. The logo is also a play on the fact that the chip has been designed for audio processing applications in mind.
