    I think the T4 I2C does not yet support DMA which means, when you are sending large blocks of pixel data, you are blocking the entire CPU while those bytes are very slowly pumped out using the standard Wire library....

    16-bit resolution is more that adequate if you use it correctly (i.e it's fine for transport, not always for intermediate math). The extra precision w.r.t. saturation and non-linear processing (i.e. distortion) is only...

    There are float as well as integer versions of most CMSIS functions. There are also DSP functions for converting to/from float. If you've got lots of CPU to spare, that's a good approach. If you can't afford to do it...

    The very short answer is yes, there would be too much overhead to process audio in blocks of 1 sample at a time, performance would be very poor. There is a direct tradeoff between latency and performance. Nearly all...
