We have been developing a configurable-reconfigurable dynamically reconfigurable processor called MuCCRA. On the processor, in order to enhance the transfer speed of the configuration data to context memory in each module, a multicast mechanism called RoMultiC is adopted. Although it contributes to speed up of configuration transfer, time for transfer is still longer than computation, especially in applications that have large configuration data.It means that configuration transfer may become a bottleneck of the total performance.
In this paper, we propose a method that improves multicast of RoMultiC and evaluate the effect using some applications. As the results, time for configuration transfer was reduced by 42% while configuration data became 83%. |
