Worm-Bubble Flow Control
2013
2013 IEEE 19th International Symposium on High Performance Computer Architecture (HPCA)
Deadlock-free flow control should be designed with minimal cost, particularly for on-chip designs where area and power resources are greatly constrained. While Bubble Flow Control, proposed a decade ago, can avoid deadlock in VCT-switched tori with only one virtual channel (VC), there has been no working solution for wormhole switching that achieves the similar objective. Wormhole switching allows the channel buffer size to be smaller than the packet size, thus is preferred by on-chip networks.
