—We consider the problem of realizing several common communication structures in the all-optical Partitioned Optical Passive Stars (POPS) topology. We show that, often, the obvious or " natural " method of implementing a communication pattern in the POPS does not efficiently utilize its communication capabilities. We present techniques which distribute the(More)
Modern computer buses are typically organized by the three functions of data transfer, addressing , and arbitration/control. In this paper we present a ber based bus design which provides optical solutions for each of these functions. The design includes an all optical addressing system, based on coincident pulse addressing, which eliminates the latency(More)
This paper presents a scalable electro-optical intercon-nection network architecture which is suitable for tightly coupled multiprocessors. The architecture is called a Partitioned Optical Passive Star (POPS). It is a type of multiple passive star topology in which only constant and symmetric coupler fanouts are used and in which exactly one coupler is(More)
This paper presents and analyzes a topological approach to providing multiple data channels using current technologies. The Partitioned Optical Passive Stars (POPS) topology is an all-optical interconnec-tion architecture that uses multiple non-hierarchical couplers. POPS topologies provide powerful conng-urability for optimization of system complexity,(More)

We consider the problem of embedding ring and torus communication structures onto the all-optical Partitioned Optical Passive Stars (POPS) topology. We show that the natural embedding, which maps the nodes in the ring or torus directly onto the POPS, does not result in an optimal embedding, and thus does not eeciently utilize the communication capabilities(More)
