ABSTRACT:
A method and apparatus for guaranteed data synchronization. In one embodiment, a data synchronization unit includes a memory unit, a write pointer unit, a read pointer unit, and synchronization pulse logic. The memory unit may receive information from a source external to the data synchronization unit. The write pointer may specify an address within the memory where incoming information is to be written. A read pointer outgoing information is to be read from. The data synchronization unit may also include synchronization pulse logic. The synchronization pulse logic may be configured to, in a synchronization mode, to generate a synchronization pulse. In response to an assertion of the synchronization pulse, the read pointer may be initialized such that data read out of the memory unit is valid (i.e. guaranteed to meet electrical requirements) at that time.
