چکیده

With large-capacity FPGAs, such as the Xilinx Virtex family, complex systems can now be constructed from reconfigurable hardware, and sophisticated designs are more easily implemented through C-language hardware compilers, such as Handel-C [1]. However, improved language support is not enough, as effective system design needs structured methods and high-level design support, which a language by itself cannot provide. This paper address the need for additional application development support by proposing a system-level asynchronous model, based on CSP (Communicating Sequential Processes) [2], and implementing an FPGA runtime environment allowing user-level ‘task’ objects to communicate via Handel-C channels.

Towards an Automated Design of Application-specific Reconfigurable Logic

Reconfigurable architectures can bridge the gap between programmable solutions (processors, DSPs) and highly optimised ASICs if they are structured in an application-specific way. Two of the main disadvantages of reconfigurable logic are its low functional density, caused by the area overhead introduced by configuration logic and memory, but also reduced clock frequencies, caused by extended si...

Dynamic coarse grained reconfigurable architectures

Coarse grained reconfigurable processors have gained more popularity in the last years, as they introduce a new way for a dynamic and programmable execution similar to FPGA and tend to achieve the performance of application specific hardware. The reconfigurability on instruction level grants these architectures a big dynamicity and ability to embrace the diversity of the applications. Neverthel...
