| Abstract(in English) | Two types of non-linear asynchronous pipeline constructs, namely Conditional Branch and Asynchronous were compared for 2-phase, 4-phase and Early Acknowledgement handshake protocols. On the course, we have developed linear and non-linear controllers for Early Acknowledgement protocol and the Asynchronous Join controller for 2-phase protocol. All the different types of controllers were implemented in standard cells enabling their use in FPGA based designs. The overheads of performing the complex operations of Conditional Branch and Asynchronous Join, were estimated in comparison to the simple linear controller of the corresponding protocol. The results show that the 2-phase protocol performs better than the other two even in non-linear pipelines. The interesting result that we obtained was that the controllers for Early Acknowledgement protocol have shown the performance of 2-phase controllers when pipelines have processing elements in-between stages which allows the overhead of the controller to be hidden in the matched delay between stages. |
