Abstract
The various embodiments described herein relate to a system for performing a serial communication between a central control block and a plurality of satellite components within a semiconductor chip. The system comprises at least one logical ring that serially connects the satellite components to the central control block. The system further comprises a centralized timer. The satellite components aid the system in obeying protocols and performing direct accesses to and/or from registers. The logical ring comprises at least one data channel that is provided for transmitting data packets and address packets. Single-envelope transactions are implemented. Errors of the satellite components associated with the single-envelope transactions are reported to the central control block as additional acknowledgement information.
