Emerging applications in the IoT domain require ultra-low-power andhigh-performance end-nodes to deal with complex near-sensor-data analytics.Domains such as audio, radar, and Structural Health Monitoring require manycomputations to be performed in the frequency domain rather than in the timedomain. We present ECHOES, a System-On-a-Chip (SoC) composed of a RISC-V coreenhanced with fixed and floating-point digital signal processing (DSP)extensions and a Fast-Fourier Transform (FFT) hardware accelerator targetingemerging frequency-domain application. The proposed SoC features an autonomousI/O engine supporting a wide set of peripherals, including Ultra-Low-Powerradars, MEMS, and digital microphones over I2S protocol with full-duplex TimeDivision Multiplexing DSP mode, making ECHOES the first open-source SoC whichoffers this functionality enabling simultaneous communication with up to 16I/Os devices. ECHOES, fabricated with 65nm CMOS technology, reaches a peakperformance of 0.16 GFLOPS and a peak energy efficiency of 9.68 GFLOPS/W on awide range of floating and fixed-point general-purpose DSP kernels. The FFTaccelerator achieves performance up to 10.16 GOPS with an efficiency of 199.8GOPS/W, improving performance and efficiency by up to 41.1x and 11.2x,respectively, over its software implementation of this critical task forfrequency domain processing.
