Abstract:
Methods, systems, and devices for one or more clock domain crossing queues are described. A queue can receive, from a first clock domain, a first command to store data in the queue. The queue can store the data at a first location indicated by a first pointer. The queue can receive, from the first clock domain, a second command to cause the second clock domain to retrieve the data from the queue. The queue can generate, based on receiving the second command, a third command synchronized with a clock of the second clock domain and to cause the second clock domain to retrieve the data. The queue can retrieve the data from the first location in the queue indicated by a second pointer associated with retrieving data based at least in part on generating the third command. The queue can transmit, to the second clock domain, the data.
