Further Information

Virtual hardware is difficult to implement even on recent dynamically reconfigurable processors when the loop body of the target application cannot be stored in the set of quickly switch-able contexts. Here, techniques for such tough cases are proposed. Differential configuration which changes only different parts of similar contexts can drastically reduce the time for re-configuration. Pairwise context assignment policy can hide the overhead of configuration with double buffering. Out-of-order context switching enables execution of available context in advance. Through an implementation example on NEC's DRP-1, it appears that the virtual hardware can be executed with practical speed by combining the proposed techniques.
