Description

technical field

[0001] The invention relates to the field of performance analysis of a computer system, in particular to a device and a method for determining the performance of a computer system's CPU. Background technique

[0002] The central processing unit (Central Processing Unit, hereinafter referred to as CPU) is one of the most important devices in a computer. Its main function is to interpret computer instructions and process data in computer software. Due to the important position of the CPU in the entire electronic computer system, its computing power and execution speed have become the indicators that people care about. A very important index to measure the CPU computing performance of a computer system is the computing peak or floating-point computing peak, which refers to the maximum number of floating-point computing that a computer can complete within a unit of time.

[0003] A measure of the ability of a computer to perform floating-point calculations is fl...
