We present an architecture for a synthesizable datapath-oriented Field Programmable Gate Array (FPGA) core which can be used to provide post-fabrication flexibility to a System-on-Chip (SoC). Our architecture is optimized for bus-based operations that are common in signal processing and computation intensive applications. It employs a directional routing architecture, which allows it to be synthesized using standard ASIC design tools and flows. We also describe a proof-of-concept layout of our core. It is shown that the proposed architecture is significantly more area efficient than the best previously reported synthesizable programmable logic core.
