N2 - As Chip Multiprocessors (CMPs) scale to tens or hundreds of nodes, the interconnect becomes a significant factor in cost, energy consumption and performance. Energy efficiency of the underlying communication framework plays a major role in the performance of multi-core systems. Recent work proposes buffer-less deflection routing as a cost effective alternative. A modified version of CONfigurable NETwork Creation Tool(CONNECT) is proposed as a buffer-less router to be lightweight and efficient. Modified CONNECT is based on parallel port allocation mechanism within the routers, that allows maximum number of flits to be deflected in a productive direction. Modified CONNECT is evaluated using uniform, transpose and inverse traffic workloads against CONNECT, BLESS and Cheap- Interconnect Partially Permuting Router (CHIPPER) on a 4x4 mesh network. Modified CONNECT saves 30% area compared to CONNECT while employing lower performance. Modified CONNECT also saves 24% in area against BLESS keeping the same performance.
