ABSTRACT:
A Local Register Network (LRN) includes multiple nodes connected together by a local register bus. The nodes each include logic circuitry, one or more configuration registers, a data path and a decoder. The local register bus is unidirectional and transfer data and addresses to each one of the nodes. The decoder in each node contains local memory maps for the node configuration registers. Each decoder determines whether an address on the local register bus maps to the associated configuration registers and whether the accessed configuration registers read data onto the local register bus or write data from the local register bus. If the address does not map to the node, the data path passes the data to the next node in the LRN network.
