IQmath_fpu32.lib 、rts2800_fpu32.lib 、rts2800_fpu32_eh.lib在28335中的应用与区别

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

  • 嘿嘿,我来补充一个吧

    rts2800_fpu32.lib与rts2800_fpu32_eh.lib的区别就是,前面的是C,后面的是C++

  • 在28335中,float运算与iQ格式运算,哪个速度快点?

  • 在28335中,float运算与iQ格式运算,哪个速度快点?

    IQ格式的也是作为float的来运行的。
