A module generator for parameterized DSP core

In this paper, a parameterized module generator of DSP core for embedded application is proposed. Some special functions for the communication applications are included in this DSP core. Moreover, key parameters of the DSP core are identified and analyzed to show their effects on performance index such as execution cycle, hardware gate count and power consumption. The parameters of the DSP core and the special functions required can be specified by user which is required by the application. The DSP core which generated by the generator is synthesizable and flexible RTL code for system integration. The turn around time of design process can be dramatically decreased. Furthermore, the generator can automatically optimize the structure of DSP core for different parameters. The design examples show that the variety of selection in implementation by using this parameterized generator and its flow provides the system designer to obtain better result in area, speed and power trade-off.
