Abstract
A common access ring (CAR) network includes a main ring and one or more sub-rings. The main ring includes one or more masters, one or more slaves, and one or more bridges. Each sub-ring is coupled to the main ring through a corresponding bridge. Each node of the CAR network is assigned a unique identifier, thereby implementing a global flat address space. One or more masters may issue requests on the CAR network, such that multiple transactions are simultaneously pending. Multiple masters may simultaneously issue requests to the same slave. However, each master cannot make more than one request at a time, and must wait until a current request is completed before making another request. The ring architecture ensures that no more than one request arrives at a slave at any given time. Requests received by busy slaves are returned to the originating masters, and may be subsequently re-sent.
