摘要:
Multi-ported memory systems (e.g., register files) employ self-timing for operational synchronization. Thus, rather than using a reference clock duty cycle for operational synchronization, as in conventional multi-ported register files, embodiments of the present disclosure employ self-timing for such operational synchronization. According to certain embodiments, self-timing is employed to synchronize all the internal events within the memory so that all the events are spaced in time for appropriate synchronization. For instance, the completion of one event leads to triggering another event, the completion of which leads to triggering another event, and so on. Thus, in one embodiment, the self-timing is achieved by referencing the operational events with the memory (or register file) to each other, rather than to a reference clock duty cycle.
摘要(中):
多端口存储器系统(例如,寄存器文件)采用用于操作同步的自定时。 因此,如在传统的多端口寄存器文件中那样,不像使用用于操作同步的参考时钟占空比,本公开的实施例采用用于这种操作同步的自定时。 根据某些实施例,采用自定时来同步存储器内的所有内部事件,使得所有事件在时间上被间隔开以进行适当的同步。 例如,一个事件的完成导致触发另一个事件,其完成导致触发另一个事件,等等。 因此,在一个实施例中,通过将存储器(或寄存器文件)的操作事件引用到彼此而不是参考时钟占空比来实现自定时。
