CCS设置中,将浮点运算设置为fpu32:
1、是否需要将IQmath.lib更改为IQmath_fpu32.lib ,rts2800.lib更改为rts2800_fpu32.lib?
2、rts2800_fpu32.lib与rts2800_fpu32_eh.lib的区别?
Codegen Floating Point RTS Library: Use the correct run-time support library for native 32-bit floating-point. For C code this is rts2800_fpu32.lib. For C++ code with exception handling, use rts2800_fpu32_eh.lib.
FPU FastRTS Library: This library provides a boost to math operations by using lookup tables available in the ROM of the device.
Link your code with the IQmath object code library. This will normally be the IQmath.lib
library. If you have a C28x with floating-point device and wish to mix IQmath and native
floating-point, then use the IQmath_fpu32.lib. This file contains all of the IQmath
functions in object format. The library is constructed such that ONLY the functions that
are used are included as part of the project. This minimizes code size
