No, look here: https://docs.rs-online.com/30f2/0900766b800310c3.pdf For 40 bit floats, you need 2 loads and 2 stores, because the then 32 bit mantissa needs to be stored in an additional location as an integer. I didn’t use that. > The SHARC definitely had support for 40-bit float (which was very cool - we > used the heck out of it) but I though the TI floating point DSPs only > supported 32-bit/64-bit float but no 40-bit float. Maybe later version, the C30 was the first FP DSP from TI. Later version like the TMS320C6xxxx are quite different, but impressive. Best, Steffan > On 14. Apr 2023, at 06:53, B.J.
