结合ESL中事务建模的方法,提出一种DSP微处理器周期精确的行为模型的建立方法。该模型描述DSP处理器设计中内部各子模块的功能划分、流水线的组织及指令的周期行为等关键问题。借助ESL仿真工具,用户可以方便地观察到处理器模型的内部操作,简化了对设计的理解,为逻辑设计和功能验证提供了参考依据,加快了处理器设计与验证的进程。

This paper presents the design and implementation of a cycle accurate behavior model for a DSP microprocessor based on transaction level modeling in ESL methodology. This model explores several key issues of a processor design, such as the sub block partition, the pipeline organization and the instruction operations in each cycle. By ESL simulation tools, it can easily understand the detailed operations of the model, which greatly helps and accelerates the process of logical design and functional verification.
