Superpipelined control and data path synthesis

The authors describe a superpipelined control and data path synthesis system. The system can handle pipelined modules in the data path, perform functional pipelining in the data path, and schedule the data path using a pipelined controller. Three control styles-serial, parallel, and pipelined-were implemented. The system automatically picks one depending on the data path, the clock frequency, and the functional unit and control path delays. The results showed that using a modifiable clock cycle time and a parameterized control style can significantly improve the throughput of high-performance systems
