Xpipes<br />
• Developed by the Univ. of Bologna and Stanford University<br />
• Source-based routing, WH switching<br />
• Supports OCP standard for interfacing nodes with NoC<br />
• Supports design of heterogeneous, customized (possibly<br />
irregular) network topologies<br />
• go-back-N retransmission strategy for link level error control<br />
• errors detected by a CRC (cycle redundancy check) block running<br />
concurrently with the switch operation<br />
• XpipesCompiler and NetChip compilers<br />
• Tools to tune parameters such as flit size, address space of cores, max.<br />
number of hops between any two network nodes, etc.<br />
• generate various topologies such as mesh, torus, hypercube, Clos, and<br />
