Hi I would like to know how a floating point number is represented in DM if the width of the DM is configured for 16 bits and PM as 48 bits. I am using the EZLITE version for ADSP-21020/60 that is showing all floating point numbers as 32 bit.

Hello, I've implemented filtering on the ADSP-21364 with a sampling rate of 48kHz. I use both analog and SPDIF interfaces. And in each case, if I enter, for example, coefficients of a low-pass filter with a cutoff frequency of 500Hz, the signal is filtered by a low-pass filter with a cutoff frequency of 1000Hz. So everything seems to be as the processor would read and write samples at ...
