OpenSPLySER: The Integrated OpenSPARC and DySER Design

Date Added: Jan 2011

The Dynamically Synthesized Execution (DySE) model has been proposed to improve the energy efficiency and performance of general purpose programmable processors. The authors describe how a DySE Resource (DySER) block can be integrated into a processor pipeline. The block size can be adjusted based on design constraints, but they integrate an 8 x 8 functional unit array into a simple in-order OpenSPARC T1 pipeline. The instruction set changes and the microarchitectural interface between the DySER block and processor are described.
