Internal parallelization of data-driven virtual hardware

WASMII and HOSMII are virtual hardware systems that execute dataflow algorithms on extended FPGAs with multiple sets of configuration RAM. Especially, HOSMII using an FPGA integrated with DRAM can effectively eliminate the overhead caused by replacement of configuration contexts. However, it has also been shown that the current HOSMII architecture cannot fully exploit the parallelism of an application. To get around this problem, internal parallelization of a HOSMII chip is discussed and evaluated through simulations
