Abstract

The embodiment of the invention discloses a performance analysis method, device and equipment and a storage medium. The performance analysis method comprises the following steps of configuring the working parameters of a plurality of performance counters in the target chip, wherein at least two performance counters in the plurality of performance counters have a cascade relationship, and the counting start time and / or the counting end time of the post-stage performance counters are / is determined by the counting state of the associated pre-stage performance counters; counting a plurality of events to be counted of the target chip through a plurality of performance counters to obtain counting data; and acquiring counting data of at least one performance counter, and analyzing the performanceof the target chip according to the counting data. According to the technical scheme, the logic combination between the performance counters can be achieved, the defect that an existing performance analysis tool is single in information is overcome, and the comprehensive analysis on chip performance is achieved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of chip performance analysis, and in particular, to a performance analysis method, device, equipment, and storage medium. Background technique [0002] With the development of the chip industry, especially after the emergence of a large number of artificial intelligence-specific acceleration chips, the increasingly complex chip design has made chip developers more urgent for chip performance analysis, and at the same time, the difficulties encountered in performance analysis have also become greater. [0003] Existing chip performance analyzers usually obtain a small amount of performance information of each hardware module based on performance counters, and provide all of the performance information to users. The user checks and analyzes the performance information based on experience to analyze the performance of the chip. The chip performance analyzer itself cannot comprehensively a...
