The present invention discloses a system for generating a software TLM model, comprising a processing unit; a compiler coupled to the processing unit to generate target binary codes of a target software; a decompiler coupled to the processing unit to decompile the target binary codes into high level codes, for example C or C++ codes, to generate a functional model of the target software, wherein the functional model includes a plurality of basic blocks; an execution time calculating module coupled to the processing unit to calculate overall execution time of the plurality of the basic blocks of the functional model; a sync point identifying module coupled to the processing unit to identify sync points of the software transaction-level modeling model; and a time annotating module coupled to the processing unit to annotate the overall execution time of the basic blocks and the sync points into the functional model to obtain the software transaction-level modeling model.

Method, system and computer readable storage device for generating software transaction-level modeling (TLM) model

The present invention discloses a high-parallelism synchronization method for multi-core instruction-set simulation. The proposed method utilizes a new distributed scheduling mechanism for a parallel compiled MCISS. The proposed method can enhance the parallelism of the MCISS so that the computing power of a multi-core host machine can be effectively utilized. The distributed scheduling with the present invention's prediction method significantly shortens the waiting time which an ISS spends on synchronization.

High-parallelism synchronization approach for multi-core instruction-set simulation

The present invention discloses a method for multi-core instruction-set simulation. The proposed method identifies the shared data segment and the dependency relationship between the different cores and thus effectively reduces the number of sync points and lowers the synchronization overhead, allowing multi-core instruction-set simulation to be performed more rapidly while ensuring that the simulation results are accurate. In addition, the present invention also discloses a device for multi-core instruction-set simulation.
