ABSTRACT:
In a system for communicating data from a processor to a plurality of register groupings that includes a plurality of registers and a plurality of register decoding logic entities, each register is associated with one of the plurality of register groupings. The plurality of register decoding logic entities is arranged in a data communication ring and is assigned to a register grouping. Each register decoding logic entity is configured to: receive a data packet that includes a data unit intended for a set of the registers in communication with the register decoding logic entity; write the data unit to each of the set of registers; determine if the register decoding logic entity is set to a relay mode; and if the register decoding logic entity is set to the relay mode, then update the data packet to reflect an address corresponding to a next register decoding logic entity in the data communication ring and then transmit the data packet to the next register decoding logic entity for which the data packet is intended.
