Embodiment Construction

[0131] refer to Figure 1-15 . The specific steps of the embedded system measuring method based on five kinds of capabilities of the present invention are as follows:

[0132] Step 1: Build an indicator system. Let U represent the evaluation index u i The set consisting of u i Represents the evaluation index u of the next layer ij The sub-set composed of evaluators l is p, evaluation gray class e is g, and d ijp The specific evaluation process is as follows:

[0133] The evaluation sample matrix D is established, and the calculation method is shown in formula (1).

[0134]

[0135] According to D, vectorize the evaluation gray level value to obtain its scoring vector C, and the calculation method is shown in formula (2). where d i Score the standardized metrics.

[0136] C=(d 1 , d 2 ,...,d g )(2)

[0137] evaluator l on the evaluation index u ij The number of gray evaluations is denoted as X ije , and its calculation method is shown in formula (3).

Abstract

The invention discloses an embedded system performance evaluation method based on five capabilities to solve the technical problem that an evaluation result of an existing embedded system performance evaluation method is poor in comprehensiveness.According to the technical scheme, an index system of the five capabilities is structured, index scores are calculated, and finally comprehensive evaluation is carried out.In the structuring process of the index system, indexes capable of reflecting the five capabilities are selected, repeated terms are removed, cross terms are separated, like terms are merged, and thus the indexes have operability.In the calculation process of the index scores, a black box method is adopted for testing indexes difficult to quantize.Random numerical value indexes are converted into numerical values between [0,1] in a normalization mode; the testing results of index testing terms which are a Boolean proposition are 0 or 1; part of index testing terms which cannot be expressed with numerical values are quantized with an empirical approach.Finally, display is carried out with a radar image.The evaluation result of the method is complete and comprehensive, and scientifically reflects the performance of the embedded system.

Description

technical field [0001] The invention relates to an embedded system performance evaluation method, in particular to an embedded system performance evaluation method based on five capabilities. Background technique [0002] Embedded system is application-centric, based on computer technology, software and hardware can be tailored to meet the application system's strict requirements on function, reliability, cost, volume, and power consumption. It can be known from the definition of embedded system that its performance is closely related to specific applications. Theories and technologies related to embedded systems are becoming more and more mature, the application fields are also expanding, and people's demands on them are also constantly upgrading. At the same time, under the premise of limited resources, higher operating efficiency is the goal that embedded systems are constantly pursuing, so how to measure the performance of embedded systems has become one of the importan...
