Method and device for simulating bottom-layer message interface

Abstract

A method for simulating a bottom-layer message interface comprises the following steps of: simulating the operating system of an executive target machine; monitoring the process switching of the codes of the operating system of the target machine, and invoking an annotation mechanism after the process switching is found and generating a bottom-layer message sub-process index table; performing identification processing on each instruction in the instruction stream of the target machine, and executing the simulation processing of the message interface when the invoking of a bottom-layer message sub-process is identified, thereby obtaining a message parameter virtual address; transforming the message parameter virtual address into a message parameter physical address; invoking the bottom-layer message sub-process index table to execute message function simulation, and realizing the transfer of a message according to the message parameter physical address. Based on the method, a device for simulating a bottom-layer message interface is also provided. The method and the device provided in the invention are capable of supporting multi-node message function simulation based on an all-structure concurrent computer state; therefore, the simulation way is simplified and the simulation efficiency of a concurrent application program is improved.

Description

technical field [0001] The invention relates to the technical field of computer simulation and emulation, in particular to a bottom message interface simulation method and a simulation device. Background technique [0002] Computer system structure modeling is to realize the structure of computer system by means of simulation. By modeling the computer system structure, researchers can use a configurable structure to investigate the behavior and characteristics of the target computer software when it is executed on the simulated system structure, so that the computer can be discovered as early as possible before the real computer system platform can be used. Structure design issues, implement the software development and debugging of the platform. Among them, full structure state simulation and message simulation are two important aspects of computer structure modeling.

AI Technical Summary

Problems solved by technology

The full instruction simulation method needs to simulate all the structures related to the internal implementation of the message. The simulation software is complex and the simulation speed is slow, which reduces the effectiveness of the simulation development and debugging of the software above the bottom layer message interface, and it is difficult to distinguish between the upper layer software and the bottom layer message software. simulated behavior

[0004] It can be seen that these methods have insufficient simulation functions or have the defects of complex simulation software and slow simulation speed, and cannot solve the problem of fast simulation of full-structure parallel computer messages.
