TaBit: A framework for task graph to bitstream generation

Nowadays, the usual embedded design flow makes use of different tools to perform the several steps required to obtain a running application on a reconfigurable platform. The integration among these tools is usually not fully automated, forcing the developer to take care of these intermediate steps. This process slows down the application development and delays its time to market. In this work we present the TaBit framework, intended for FPGA designers, that is able to guide the developer from the original partitioned application, described as a task graph, down to its deployment onto the target device. Moreover, this framework defines a set of interfaces that allows the developer to integrate custom scheduling and floor placing techniques. The framework takes care of the integration between the different steps and, based on the designer inputs, it is able to automatically generate a software Scheduling Engine and the set of bitstreams ready to be deployed onto the target device.
