And as with the previous floating point, it's 20 to 30 times times slower than the whole number. , but because of the floating point accelerator, the speed of the floating point can be 1.3 times times that of the whole number!

instruction set rather than the CPU core is the most decisive factor. The powerful X86 architecture is also derived from the powerful instruction sets. For example, we know that atom, although its x86 core is very weak, but because it supports sse3, in many cases, the performance can even exceed the core performance, far more powerful than its Pentium M, which is the power of the instruction set. At present, the x86 Instruction Set has evolved from

can optimize a CPU model and a system to reduce the file size, CPU usage, and memory usage.However, programs compiled by specifying optimization parameters do not have cross-system cross-platform capabilities. Even if the system versions of the two machines are the same, the program cannot run as long as the CPU is different. The program can only run on the compiled machine. In general, the optimization parameters are set through the export command CFLAGS and CXXFLAGS, and will be automatically
