Autonomous FPGA Reconfigurability in Embedded Systems

Advances in field-programmable gate array (FPGA) technology have led to their widespread adoption in various applications, from embedded systems and data centers to high-performance computing. FPGAs provide a flexible and cost-effective solution for implementing digital logic, offering a unique balance between performance, power consumption, and reconfig-urability. The ability to generate and load the FPGA's configuration data, known as the bitstream, is a crucial aspect of FPGA-based system design, as this bitstream defines the FPGA's functionality and behavior. Recently, architectures that integrate FPGA technology with embedded processors have become increasingly popular, enabling the creation of highly versatile systems-on-chip. In this work, we introduce a design methodology that employs open-source tools to enable the generation of FPGA bitstreams directly within embedded processors. This approach harnesses the advantages of FPGA-based systems, such as their reconfigurability and high-performance characteristics, while smoothly integrating them with embedded processors. Additionally, we propose several research directions and applications where this novel paradigm can be leveraged to develop innovative solutions.
