Compiler/DRA72XEVM: Floating-point increase precision C66x

Part Number:DRA72XEVM

Tool/software: TI C/C++ Compiler

Hi,

I am looking into increasing precision on various math operations on a c6x-dsp.I found that the floating-point control registers FADCR, FAUCR and FMCR mentions denormalized numbers. The manual SPRUGH7 gives a brief explaination on the content of these registers.

I would for example want
32bit float operation 1.0e-37 *0.01 ~= 0 and
64bit float operation 1.0e-307 *0.01 ~= 0.

Is this possible on a c66x dsp?

Thanks,
Joakim
