Title: System for high-speed data transfer using a sequence of overlapped global pointer signals for generating corresponding sequence of non-overlapped local pointer signals

Abstract: A circuit architecture and methodology for providing burst data transfer in high-speed digital circuit applications implements a sequence of overlapped global-pointer signals for generating corresponding sequence of non-overlapped local-pointer signals. One of the global pointer signals starts to be activated per cycle and the pulse width of each global pointer signal is greater than the burst cycle time. A global pointer signal <i> of a sequence (where i is one of the integers <1:n>) is used to generate a corresponding local pointer signal <i> that is reset by detecting a time at which the global pointer signal <i+1> starts to be activated. This allows for generation of reliable non-overlapped local pointer signals, while using overlapped global pointer signals. Each local generated pointer signal is used to accomplish a respective data transfer, e.g., from an individual latch to a single data line.
