Bus model-based embedded system emulated platform

Abstract

The invention relates to an embedded system simulate platform based on bus model, which leads in the embedded system flexible bus design theory, to realize the uniformity of various embedded system bottom structure, and use a system model language SystemC to build a processor host simulate model and an expansion interface board simulate model. The processor host simulate model comprises an embedded processor function model, an interface bus mission model or a SOC (on-chip system) function model, and an on-chip mission model. The invention uses software / hardware cooperate design and simulation integrated environment to realize the development of embedded system simulation model, and uses a real-time parallel simulation console to realize the parallel execution and detection of embedded system simulation model.

Description

(1) Technical field: [0001] The invention relates to a simulation platform for an embedded computer system implemented on a general-purpose computer, in particular to a complex embedded system simulation platform established by using an embedded computer bus model, and belongs to the field of computer technology. (2) Background technology: [0002] The embedded system is defined as a "special computer system embedded in the object system". "Embeddedness", "specificity" and "computer system" are the three basic elements of an embedded system. At present, with the development of instrument systems in the direction of functional integration, small-scale portability, etc., embedded systems have penetrated into every corner of the national defense, military, and civilian electronic systems. [0003] With the expansion of the application of embedded systems and the exploration of depth, the tasks that people assign to embedded systems are becoming more and more onerous, the algorithms ...

AI Technical Summary

Problems solved by technology

The smallest system design with embedded processors can get perfect simulation support, but once more interface boards are expanded, the strength of system-level simulation support will decrease rapidly

[0006] 2) Due to the lack of effective description means for the hardware model, the simulation system based on PC is limited to soft tasks such as algorithm verification and effect demonstration, and does not really undertake the simulation mission of system architecture demonstration and interface implementation reference

[0007] 3) The simulation system is usually in the status of a supporting product, which is established and specific, and it is difficult to adapt to the needs of changes in simulation objects (especially system structure changes)
