most CPUs currently support floating-point unit FPU,FPU as a separate coprocessor placed outside the processor core, but for embedded processors, floating-point operations are inherently less used, and some embedded processors remove the floating-point coprocessor.X86 processors generally have the FPU. And the ARM PPC MIPS processor will appear without the FPU phenomenon.Linux kernel How to handle floating-

Linux Kernel support for the S3C2410 sleep mode I. S3C2410 supports four Power Supply Modes (1) Normal Mode Maximum power consumption. you can disable the clock of a specific controller to reduce power consumption. (2) Slow Mode In this mode, there can be no internal PLL, and the power consumption depends on the frequency of the external clock. (3) idle mode Fclk
