Design and Implementation of an On-Chip Permutation Network for Multiprocessor System-On-Chip

Manjunath E, Dhana Selvi D

The novel on-chip network in silicon proven design to support guaranteed traffic permutation in multiprocessor SOC applications. A pipelined circuit-switching Employed in the proposed network with FIFO approach combined with a multistage network topology in dynamic path-setup scheme. The runtime path arrangement enabled by dynamic path-setup scheme for arbitrary traffic permutations along with the Error Correction Block (ECB). The circuit-switching approach offers the permuted data and its compact overhead enables the benefit of stacking multiple networks in system on chip. A CMOS test-chip with 0.13m validates the feasibility and efficiency of the proposed design. The shown experimental result in the proposed on-chip network achieves 1.9x to 8.2x reduction of silicon overhead compared to other design approaches.
