Embodiment Construction

[0021] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0022] like figure 1 As shown, the present invention provides a method for dynamic assembly instruction statistics, comprising the following steps:

[0023] Step 1: Analyze the binary code structure of the target application program on the module under test, and identify the instruction types in the binary code of the target application program. The instruction types include jump instructions and non-jump instructions.

[0024] Step 2: According to the binary code instruction type of the target application program, determine the position where the statistical instruction needs to be inserted according to the insertion condition. The insertion condition is: insert a statistical instruction after each jump instruction; insert a statistical instruction after N consecutive non-jump instructions, and N is greater than or equal to 2. That is, the conditions for inserting...

Abstract

The invention discloses a dynamic assembly instruction statistical method and a device, wherein the method comprises the following steps: the binary code structure of a target application is analyzed, and the instruction type is identified; positions in which statistical instructions need to be inserted are determined according to the insert conditions and the instruction type; the statistical instruction codes are inserted into the positions in which statistical instructions need to be inserted; the corresponding statistical instructions run together with the target application, and statistical information is transmitted to a data receiving module to be stored in real time; the insert conditions are as follows: one statistical instruction is inserted after each jump instruction; and one statistical instruction is inserted after N continuous non-jump instructions, and N is more than or equal to 2. According to the dynamic assembly instruction statistical method and the device, the dynamic use of instruction in the target application can be analyzed in a statistical manner, the input data information of a computing module CPU (central processing unit) in a computer can be accurately known, proof is provided for improving the computing capability, meanwhile the influence of the statistical instruction codes to the target application is reduced to the greatest extent.

Description

technical field [0001] The invention relates to computer network technology, in particular to a method and device for statistics of dynamic assembly instructions. Background technique [0002] At present, cloud computing has become a hot spot in computer network technology. In the research of cloud computing, computing power is regarded as a commodity and circulated through the Internet. In the evaluation of computing power, in addition to the characteristic parameters such as the structure and function of the computer being evaluated, it is also closely related to the input (that is, the workload of the computer system, the target application program), especially the execution of the target application program. Computing capabilities of various instructions and instruction strings that appear during the process, that is, it is necessary to evaluate the computing capabilities of various instructions and instruction strings that appear during the execution of the target appli...
