Abstract: A triplet based architecture(TriBA) is proposed following the method of decomposition of complex problems.TriBA is easily extendable and has fractal characteristics.An object-oriented chip multi-processor(OOCMP) is presented based on TriBA.The chip supports truly parallel execution of objects from the hardware and achieves the unification of software architecture and computer architecture.Processors on the same chip are connected via triplet based hierarchical interconnection network(TBHIN),which has simple topology and the characteristics of computing locality.Four basic software stream models are discussed based on the TBHIN network.
