cpu-speed

问题 Programs like CPUz are very good at giving in depth information about the system (bus speed, memory timings, etc.) However, is there a programmatic way of calculating the per core (and per processor, in multi processor systems with multiple cores per CPU) frequency without having to deal with CPU specific info. I am trying to develop a anti cheating tool (for use with clock limited benchmark competitions) which will be able to record the CPU clock during the benchmark run for all the active

问题 I know this is a micro-optimization, so I ask out of pure curiosity. Logically, a microprocessor does not need to compare all the bits of both operands of an equality operator in order to determine a \"FALSE\" result. Note, this is programming-related because it affects the execution speed of a program. 回答1: Usually, the microprocessor does comparison using electrical gates and not step by step like that. It checks all bits at once. 回答2: This depends on your platform, but in general, it will
