CoreAXItoAXIConnect


CoreAXItoAXIConnect is a lightweight AXI interface connector designed to enable seamless cascading of multiple CoreAXI4Interconnect modules within FPGA-based systems. It serves as a bridge between the slave interface of one interconnect and the master interface of another, enabling scalable and modular AXI-based system architectures. Unlike traditional interconnect elements that introduce logic, buffering, or arbitration, CoreAXItoAXIConnect is purely a connectivity component with no internal logic or storage elements. It simply provides direct signal connectivity between master and slave interfaces while maintaining protocol integrity. This architecture ensures zero additional latency and negligible resource utilization, making it ideal for designs that require efficient expansion of AXI interconnect fabrics. CoreAXItoAXIConnect is particularly useful in hierarchical or large SoC designs where multiple interconnects are needed to manage complexity and improve scalability. By enabling clean interconnect partitioning without additional overhead, it helps designers build high-performance, modular systems while maintaining efficient resource utilization.
