In some applications on dynamically reconfigurable processor (DRP), the input/output of data stream occupies about 20% of total execution time. In order to hide the overhead of input/output, the separation of the I/O context and double-buffering mechanism are proposed. Using the mechanism, I/O overhead of six streaming processing programs can be completely hidden. Based on the analysis of I/O performance, two alternatives for executing parallel processing with multiple DRP cores are compared and discussed.
