MSP430浮点库

READ ME FIRST for the MSP430 Floating Point Package for IAR.

Included files:
==============
FPP.prj        Workspace project file to assemble the FPP
FPP.s43        Source file to assemble the FPP
CNV04.s43      FPP integer conversion subroutines
Fpp04.s43      FPP
fppdef4.s43    FPP register definitions
FPPFNC4.s43    FPP trigonometric and other functions

The FPP package is documented in MSP430 Family Applications Reports, 2000, SLAA024,
chapter 5.6. The examples presented in the document are written for the TI assembler;
minor changes to the assembler directives may be required in order to use the examples
with the IAR assembler. Refer to the FET User's Guide for a discussion of converting
source from TI-format to IAR-format.

The FPP source is compatible with the IAR assembler.

The FPP package *** IS NOT *** compatible with the IAR floating point assembler directive DF.
Refer to chapter 5.6.5 of SLAA024 for a discussion of the internal data representation used
by the FPP.

Fixes:
======
-> 4.10 Fixed bug in FPPFNC4.s43
   Function:       FLT_SQRT
   Line:	   SQ1	BIS.B	030h,0(SP)	; Exponent is odd: add correction
   Replaced with:  SQ1	BIS.B	#030h,0(SP)	; Exponent is odd: add correction
