Embodiment Construction

[0024] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0025] The processor performance evaluation method in the prior art requires the tracking unit to output the tracking stream containing the detailed operating information of the processor in real time, which increases the cache and bandwidth pressure of the tracking unit, and increases the calculation time and complexity of the processor performance index value . To solve this problem, the present invention provides a technical sol...

Abstract

The invention discloses a processor performance evaluation method, which is suitable for generating an evaluation component for evaluating the performance of a processor, and the evaluation component comprises at least one adjustable parameter. The method comprises the following steps: obtaining an execution result sequence of a calibration program executed by the processor, the execution result sequence comprising a plurality of instructions arranged according to an execution sequence; calculating a performance index value of the processor by using the current evaluation component according to the execution result sequence; acquiring accumulative operation information of the processor during the period of executing the calibration program, and determining an actual performance index value of the processor according to the accumulative operation information; and adjusting parameters of the evaluation component by comparing the performance index value calculated by the evaluation component with the performance index value so as to reduce an error between the performance index value calculated by the evaluation component and an actual performance index value. The invention also discloses a processor performance evaluation method for evaluating the performance of the processor by adopting the generated evaluation component and a corresponding device.

Description

technical field [0001] The invention relates to the technical field of processor performance analysis, in particular to a processor performance evaluation method and a corresponding device. Background technique [0002] With the development of network communication technology, today's society has entered the era of Internet of Things (IoT). Embedded technology is the basis for the realization of the Internet of Things. In the development stage of the embedded chip, the developer needs to write multiple programs and burn the programs into the memory of the embedded chip. After the embedded chip is developed, it can be integrated into smart devices. When the processor of the embedded chip executes the program stored in the memory, the smart device can start working and realize corresponding functions. [0003] The quality of the program's writing affects the processing performance of the processor. Therefore, before the program is programmed into the memory, it is usually ...
