Integrating an embedded FPGA into SoC allows post-fabrication changes. Thanks to their unlimited reconfigurability, eFPGAs are able to implement specific functions, thus improves the systems performance. In this paper the authors present an SRAM-based eFPGA architecture. The authors explore the hardware aspects of the eFPGA including internal structure and external coupling with a VCI interconnect. The authors also focus on the design flow for the implementation and the configuration.
