A power-tracking embedded buck–boost converter with a fast dynamic voltage scaling (F-DVS) function is proposed to power the system-on-a-chip (SoC) system. To meet the power request of the SoC for different operation functions, fast up/down-tracking is implemented to achieve the F-DVS function. Recycling energy is also derived to minimize power dissipation during the down-tracking period. In addition,...
A virtual channel (VC) calculation algorithm for wormhole-switched on-chip networks is proposed. Traditionally, the virtual channels were allocated uniformly, which results in a waste of area and power. To remedy this situation, based on the queuing theory, we propose a router analytical model. Using this model, the proposed algorithm calculates the bandwidth usage at each router in the network according...
A new deadlock-free dynamic routing algorithm is proposed for wormhole-switched network-on-chip. Introducing the concept of multilevel congestion-aware mechanism which conveys more accurate feedback information about network congestion status than the DyAD routing, the proposed algorithm adopt proper routing algorithm to forward packets according to the current congestion level. Simulation results...
