Abstract: | This paper presents a communication network targeted for complex system-on-chip (SoC) and network-on-chip (NoC) designs. The
Heterogeneous IP Block Interconnection (HIBI) aims at maximum efficiency and minimum energy per transmitted bit combined with
quality-of-service (QoS) in transfers. Other features include support for hierarchical topologies with several clock domains,
flexible scalability, and runtime reconfiguration of network parameters. HIBI is intended for integrating coarse-grain components
such as intellectual property (IP) blocks that have size of thousands of gates.HIBI has been implemented in VHDL and SystemC
and synthesized on several CMOS technologies and on FPGA. A 32-bit wrapper requires 5400 gates and runs with 315 MHz on 0.18
μ m technology which shows that only minimal area overhead is paid for the advanced features. The area and frequency results
are well comparable to other NoC proposals.Furthermore, data transfers are shown to approach the maximum theoretical performance
for protocol efficiency. HIBI network is accompanied with a design framework with tools for optimizing the system through
automated design space exploration.
