In this chapter, the floating-point unit (FPU) is looked at. Some ARM documentation refers to this as the vector floating-point (VFP) coprocessor to promote the fact that it can do some limited vector processing. Any vector processing in the FPU is now replaced by the much better parallel processing provided by the NEON coprocessor that will be studied in Chapter 12, “Neon Coprocessor.” Regardless, the FPU provides several useful instructions for performing floating-point mathematics.

摘要

In this chapter, the floating-point unit (FPU) is looked at. Some ARM documentation refers to this as the vector floating-point (VFP) coprocessor to promote the fact that it can do some limited vector processing. Any vector processing in the FPU is now replaced by the much better parallel processing provided by the NEON coprocessor that will be studied in Chapter 12, “Neon Coprocessor.” Regardless, the FPU provides several useful instructions for performing floating-point mathematics.
