Abstract:
1. A method comprising: receiving data from a second device in a first device; forwarding the data from an input/output (I/O) clock domain to a system clock domain of the first device through a routing path including a delay line; loading the data into a buffer of the system clock domain according to a load pointer, wherein the load pointer is controlled by a looped-back reset signal received in the system clock domain from the I/O clock domain via the routing path, the looped-back reset signal received in the I/O clock domain from the system clock domain via the routing path and from a reset signal initiated in the first device; and unloading the data from the buffer and into a functional unit of the first device according to an unload pointer, wherein the unload pointer is controlled by an unload signal based upon the reset signal.
