Part Number: AM2632-Q1
Other Parts Discussed in Thread: AM2632
Hi,
It doesn't clear enough in the datasheet.
Does this µC AM2632 include a hardware FPU simple (32bit) or double (64bit) precision?
Thanks.
Marc
Marc,
I agree it could have been stated more explicitly.
If you look at the TRM, section 7.1.1.1, you will see it mentions
Full-precision floating point (VFPv3-D16)
-> VFPv3-D16 indicates it supports single and double precision floating-point in hardware.
Thanks,
Sira
I know this but it doesn't clearly explain in ARM website that this VFPv3-D16 support double 64bit hardware FPU.
Indeed, even Gemini says that this FPU doesn't support double 64 bit float hardware calculation.
Please, give me the µC instruction manual that defines the assembler instruction mul. for double float.

Hi Marc,
The Floating point unit is provided by ARM, thus the instruction set manual is also provided by ARM.
