Rapid Prototyping of the Data-Driven Chip-Multiprocessor (D2-CMP) using FPGAs

In this paper, the authors present the FPGA implementation of the prototype for the Data-Driven Chip Multi-Processor (D2-CMP). In particular, they study the implementation of a Thread Synchronization Unit (TSU) on FPGA, a hardware unit that enables thread execution using dataflow-like scheduling policy on a chip multiprocessor. Threads are scheduled for execution based on data availability, i.e., a thread is scheduled for execution only if its input data is available. This model of execution is called the Data-Driven Multithreading (DDM) model of execution. The DDM model has been evaluated using an execution driven simulator.
