Abstract
For solving the traditional deficiencies of reconfigurable system such as the poor flexibility of tasks model, the long time of hardware tasks configuration,the low resource utilization of FPGA, this paper proposed to partition a software application into software tasks and hybrid tasks. Secondly through extension of eCos in three aspects including reconfigurable control mechanisms, hybrid tasks management and inter-task communication mechanisms, this paper presented an embedded operating system prototype called eCos4RC which was compatible with the multi-thread mechanism of eCos. The experiments results indicate eCos4RC could manage the hybrid tasks and reconfigurable computing resources effectively, and provide a runtime support for reconfigurable computing platforms while reducing the execution time of application.关键词
