: The main purpose of this article is to present how to use shobi-PN, an Object-Oriented PN model to quickly specify a data path/control system. In a case study, a transputer link adaptor has been specified by applying the shobi-PN model for rapid-prototyping and to generate VHDL code for simulation purposes. The case study demonstrates the applicability and the capability of a hardware design flow, supported by the use of object-oriented principles to model both the control unit and the data path of complex systems, with a developed CAD tool.

In this paper we present CoR a resource oriented computing model that address the question of how to integrate user-level fine-grained multithreading, communication and coordination into a cluster of symmetrical multiprocessor computers. To support the design of complex distributed application using the proposed paradigm we built pCoR a run-time system which has new areas that represents extensions to the strict shared memory and message passing models supported by other platforms: remote operations, dynamic domains, communication ports, multithreading management, shared memory, replication and partition are some of its distinguished features. In addition, it provides a thread-safe transport communication layer to take advantage of modern high-performance commodity hardware/software like Myrinet network. 1
