چکیده

We present a runtime environment that partially reconfigures and executes hardware tasks on Xilinx Virtex. To that end, the FPGA’s reconfigurable surface is split into a varying number of variable-sized vertical task slots that can accommodate the hardware tasks. A bus-based communication infrastructure allows for task communication and I/O. We discuss the design of the runtime system and its prototype implementation on an reconfigurable board architecture that was specifically tailored to reconfigurable hardware operating system research.

Linear Placement for Static / Dynamic Reconfiguration in JBits

Placement of functional units on an FPGA fabric is a challenging problem for runtime reconfigurable computing systems. We introduce the concept of physical contexts to greatly reduce the complexity of the placement and routing problems. We have implemented static and dynamic linear placement methods for expression trees placed in physical contexts. Our placement algorithms are implemented in th...

Supporting Operating Systems for Reconfigurable Computing: A Distributed Service Oriented Approach

Operating systems for reconfigurable computing are becoming an attractive field of research. They provide a well-defined programming model and a run-time environment, which greatly simplifies the development process and management of reconfigurable applications. One of the main challenges for the design of such systems is to provide both powerful and efficient abstractions to deal with the comp...

Runtime Environment for Dynamically Reconfigurable Embedded Sy

A runtime environment has been developed to enable the seamless integration of different hardware and software implementation technologies (DSP’s, FPGA’s, ASIC’s). The runtime environment is responsible for the management of dynamic system reconfiguration, including software reconfiguration for the parallel DSP’s and hardware reconfiguration for the FPGA’s in the system. This paper describes th...
