Abstract
Multiple ARM devices, each having multiple processing elements, linked together by an interconnect to form a coherent memory fabric in which each device has access to all of the processing elements located on all of the devices that are part of the coherent memory fabric. In order to comply with the ARM architecture, the system must have a global timer that is accessible to all of the ARM devices so that each of the devices can maintain the same timer value. The devices, systems, and methods disclosed herein provide for initial synchronization between multiple ARM devices that are joined together to form a coherent memory fabric. The initial synchronization is achieved by determining an offset between the timers of each ARM device and then minimizing the offset. The synchronization may be periodically checked and adjusted, as necessary, to maintain proper synchronization.
