Abstract

PURPOSE:To obtain a highly accurate calculating method for the execution cost of sentences by forming an object list in a data processor. CONSTITUTION:A signal decision part 41 is formed in the data processor 4 for calculating the execution cost of sentences and actuated by an execution execution cost calculating signal to actuate a table control part 42. The control part 42 retrieves an object program 44 and stores an instruction unit corresponding to the program in the object list as a list. At the execution of a sentence, its execution cost is calculated from the cost of the corresponding instruction unit obtained from an instruction unit storing part 43 and the instruction unit of the object list 45 on the basis of the object list 45.

式に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for calculating the execution cost of a statement used in analyzing a program executed in a data processing system.

効率のよいプログラムの改修を行う。Efficient use of a data processing system is necessary for processing data, and this operational efficiency also varies depending on the program being created. Therefore, in order to investigate the operational efficiency of a data processing device, it is necessary to analyze the operational program and find out the expensive parts of the program. Modify the program more efficiently using the costs found through analysis.

して設定されている。The method of calculating the execution cost of a statement for program analysis is as shown in FIG. 2. That is, when the search unit 2 searches the table 1 that stores costs for each sentence and executes a corresponding sentence, for example LEAD, the cost is 100.
, REIAIND is executed, the cost 10 is extracted, the product is multiplied by the number of executions, the total sum is performed in the arithmetic unit 3, and the total execution cost of the program is calculated by the sum of each statement. This cost per sentence has conventionally been set based on the approximate number of processing steps.

解析に支障を来す。In the above calculation method, since the cost value is not estimated from the machine instruction actually executed, the cost per sentence is approximate, and accurate cost calculation is not possible. For example, if processing is performed using a WRITE statement, the cost will be the same regardless of the amount of output. This execution cost calculation method poses a problem in program tuning, especially in analyzing large programs.

の計算方式が要望されている。Therefore, there is a need for a highly accurate method for calculating statement execution costs in program analysis.

する。The present invention aims to solve the above problems and provides a highly accurate statement execution cost calculation method. The means for doing so are shown below. In a data processing device system that calculates an execution cost from the cost per sentence and the number of times a statement is executed, an object list is attached to the data processing device. The object list includes a sequence of machine instructions that are actually executed for each sentence1, and the cost per sentence is estimated based on the object list to calculate the execution cost of the sentence.
