| Abstract: |
In this paper, we approach the rather new area of reconfigurable hardware operating systems in a top-down manner. First, we describe a design concept that defines basic abstractions and
operating system services in a device- independent way. Then, we refine this model to an implementation concept on the Xilinx Virtex XCV-800 technology. The Implementation concept proposes a
multitasking environment that exeutes relocatable hardware tasks, uses a memory management unit translating task requests to internal and external memory accesses, and relies on device drivers
and triggers to connect to external I/O. Finally, we present a detailed prototypical implementation of and an application case study. The application consists of a set of dynamically loaded and
executed networking and mulitmedia tasks such as IP packet processing, AES decryption, and audio stream decoding. |
