High-performance reconfigurable computing has demonstrated its potential to accelerate demanding computational applications. Thus, the current trend is towards combining the microprocessor with the power of reconfigurable hardware in embedded system research area. However, integrating hardware and software that is the interface of communication is challenging. In this thesis, we present a methodology flow to improve the cohesion between hardware and software for reconfigurable embedded system design through IRES (I-link for Reconfigurable Embedded System), Hardware-Software integration platform. In IRES, we set up the platform and produce the Executor through I-link (Hardware-Software Integration Link). The Executor consists of tasks and hardware bitstreams which are provided by user design, bootloader and operation system which are provided by system, and PSPs (Program Segment Prefix) which are from the files given above. We initial the system through bootloader which will scan the PSPs of Executor to construct Task Control Block (TCB), Hardware Control Block (HCB) and Netlist IP Information Block (NIB) data structure. User can get the hardware information from those data structures, and communicate with hardware by using simple functions like ¡§read()¡¨ and ¡§write()¡¨. Then, the system transmits the data to and from multi-hardware through Hardware Management Unit (HMU) which also has data buffering ability. Finally, we successfully accomplish IRES Hardware-Software integration platform in HSCP, which is developed in our laboratory, and verify the feasibility of communication between hardware and software.
