Buffer Minimization of Real-Time Streaming Applications Scheduling on Hybrid CPU/FPGA Architectures
The authors address the problem of real-time streaming applications scheduling on hybrid CPU/FPGA architectures. The main contribution is a two-step approach to minimize the buffer requirement for streaming applications with throughput guarantees. A novel declarative way of constraint based scheduling for real-time hybrid SW/HW systems is proposed, while the application throughput is guaranteed by periodic phases in execution. They use a voice-band modem application to exemplify the scheduling capabilities of the method. The experimental results show the advantages of the techniques in both less buffer requirement and higher throughput guarantees compared to the traditional PAPS method.
