Subject: [oc] FPU core
Hi all,In my VHDL design I need to operate using float. I think I am going to use
FPU core of opencores. The problem is that I need to multiply unsigned
integer (16 bits) with float (32 bits single precision floating point), so I
suppose I have first to convert integer into float. What is the simplest way
to do this conversion?Is there some library or core?
The whole operation is: (it is use to calibrate Power received in a SFP)
a_4(32 bit float) * rxPwr^4(16 bit unsigned integer) + a_3(32 bit float) *
rxPwr^3(16 bit unsigned integer) + a_2(32 bit float) * rxPwr^2(16 bit
unsigned integer) + a_1(32 bit float) * rxPwr(16 bit unsigned integer) +
a_0(32 bit float)
Thanks in advance
