Network processors have become central elements in the design of modern routers. With higher line speeds and more demanding functional requirements, design of network processors has increased in difficulty. In this paper an analytic performance model for a multiprocessor-based single chip network processor is presented and used to aid in the design process. The model contains a number of worklo...

The Totem protocol supports the maintenance of consistency of replicated information in fault-tolerant distributed systems by providing reliable totally ordered delivery of messages. The membership algorithm of Totem maintains a consistent view of processors in a local-area network and handles all aspects of reconnguration, including restarting of failed processors and remerging of partitioned ...

We show that every context-sensitive language can be accepted by an accepting network of non-increasing evolutionary processors with one substitution processor and one output node whose communication is controlled by regular languages. Every recursively enumerable language can be accepted by a network with three evolutionary processors: one substitution processor, one insertion processor and on...

In this note we introduce some parallel in−core technique for sorting integer keys which is based on the regular sampling technique. We sketch an algorithm which is devoted to clusters of non homogeneous processors (the speeds of processors and/or the speeds to access distributed disks in the clusters are correlated by a multiplicative constant factor and/or the bandwidth of the underlying netw...

Processors are ubiquitous in today's world. Almost any electronic device contains a processor, and their computing power ranges from a few thousand to millions of instruction per second. Processors are built for many different purposes, and so their capabilities vary greatly. Even within a specific area, processors are different enough to make it difficult to compare them. Benchmarks have been ...

Network on chip (NoC) processors utilize network connections in place of traditional bus or cross bar interconnects in order to improve performance, power consumption, and scalability in modern multicore processors. However, superimposing a network onto a chip introduces additional factors, such as network latency, routing, and buffer depths all begin to affect the behavior of the system. Commu...

Photonics offers high hopes for next-generation neural network processors. Now it has been shown that even entirely using off-the-shelf photonics allows surpassing speed and energy efficiency of cutting-edge GPUs.
