Systems and corresponding methods employ an object-oriented (OO) memory (OOM) to effect inter-hardware-client (IHC) communication among a plurality of hardware clients included in same. A system comprises a centralized OOM and the plurality of hardware clients communicate, directly, to the centralized OOM device via OO message transactions. The centralized OOM device effects IHC communication among the plurality of hardware clients based on the OO message transactions. Another system comprises a plurality of OO memories (OOMs) capable of inter-object-oriented-memory-device communication. A hardware client communicates, directly, to a respective OOM device via OO message transactions. The inter-object-oriented-memory-device communication effects IHC communication among the plurality of hardware clients based on the OO message transactions.
