This paper presents a new direct implementation of a popular RTOS with an associated application -the WiMAX physical layer -on reconfigurable computing architectures. A novel coarse-grained reconfigurable instruction cell based architecture is chosen as the target architecture. Firstly an RTOS -Micro C/OS-II -was ported to the target architecture, and then the WiMAX physical layer program was partitioned...
We introduce a new execution model for orchestrating the interaction between the conventional processor and the re-configurable compute unit in adaptive computer systems. We then characterize the architectural and OS-level requirements of implementing the model, and demonstrate how they can be achieved on a real hardware platform running under a full scale multi-tasking virtual protected memory operating...
