Accelerating the CPU of a computer can enhance processor performance,execute instructions faster,and complete data processing tasks more efficiently.With the increase in computational tasks and the higher load on applications,CPU acceleration is essential to provide the necessary computing power for computers,ensuring system compatibility and future scalability.The C++language can indirectly a-chieve CPU acceleration by writing programs that utilize the CPU's specific instruction sets,significantly improving the performance of computation-intensive tasks.Therefore,this paper will conduct in-depth re-search and analysis on the paths to accelerate CPU in X86 architecture computers using C++,elaborate on the key points of CPU acceleration in the X86 architecture,and analyze the strategies for CPU acceler-ation implemented in C++,providing support for enhancing computer performance.
