In the context of neural network inference on embedded systems, overall performance is usually poor because of the limited resources available: small amount of ROM, RAM, low MCU frequency. This limits both the complexity of the model - and with it the amount of ‘things’ the system can recognize - as well as …

Development of a MFCC core in a FPGA Overview In sound processing, the mel-frequency cepstrum (MFC) is a representation of the short-term power spectrum of a sound, based on a linear cosine transform of a log power spectrum on a nonlinear mel scale of frequency. Mel-frequency cepstral coefficients (MFCCs) are …
