In modern ARM CPU architecture, pipeline technology is one of the key means to enhance processor performance. It divides the instruction execution process into multiple stages, allowing multiple instructions to be in different execution stages at the same time, thus achieving parallel processing of instructions and greatly improving the CPU’s execution efficiency. However, in actual … Read more
