Abstract
A queued interface device configured to communicate with a peripheral includes a first interface configured to receive and store a first set of peripheral requests from a first core, a second interface configured to receive and store a second set of peripheral requests from a second core, and an arbitrator coupled to the first interface and the second interface. The arbitrator, which may include multiple sets of registers to store the peripheral requests, is configured to selectively send the first set of peripheral requests and the second set of peripheral requests to the peripheral. The peripheral simultaneously appears as a dedicated peripheral for both the first and second cores.
