I constructed a digital vocoder out of a TMS320C30. In the documentation, denormals or FTZ isn’t even mentioned, it’s not IEEE conforming anyway. The only thing is “Underflows are handled, by settingthe result to zero and setting an underflow flag.” (SPRA397.pdf from ti.com <http://ti.com/>) Back then it was an impressive workhorse with low power consumption, using a 40 bit floating point format, if needed. Daniel Weiss used it for his shiny EQ and compressor.
