Abstract: 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.

Key words: ESL design methodology, DSP microprocessor, processor design, behavior model
