A robust self-calibrating transmission scheme for on-chip networks

Abstract: Abstract-Systems-on-Chip (SoC) design involves several challenges, stemming from the extreme miniaturization of the physical features and from the large number of devices and wires on a chip. Since most SoCs are used within embedded systems, specific concerns are increasingly related to correct, reliable, and robust operation. We believe that in the future most SoCs will be assembled by using large-scale macro-cells and interconnected by means of on-chip networks. In this paper, we examine some physical proper… Show more

“…The deterministic nature of ISI allows a variety of techniques to be used to suppress its effect. In addition to FFE, DFE and ISI reduction encoding, which were introduced previously, [32] uses line multiplexing to temporally space the use of wires and thus reduce the impact of ISI on their signals, while [33] proposes using error-rate controlled DVFS in order to increase the delay and thus adaptively reduce the effect of ISI, when errors are detected.…”

“…The computation of an average delay is too complex for the limited resources available to an on-chip link controller [10]. As a result, we approximate the average delay by the delay experienced by the last word queued in the FIFO.…”

“…When a dedicated supply voltage is available to generate the low-swing signal, then the power is again quadratically dependent on the swing. Many low-swing techniques with a dedicated supply voltage (either generated on-or off-chip) for the transmitter have therefore been introduced in the past [15,84,85,182].…”
