Technological trends have brought the growing disparity between processor and memory speeds. This memory wall problem is becoming very serious especially in high performance computing. In this paper, we propose a new architecture SCIMA for solving this problem. In SCIMA, addressable memory is integrated into the processor chip besides ordinary cache. Since the on-chip memory is software control...

We present a special-purpose computer architecture for the qualitative simulator QSim, which is mainly used in artiicial intelligence (AI) applications. This architecture consists of DSPs TMS320C40 and specialized coprocessors (Xilinx FPGAs). We stress the distinct algorithm characteristic of qualitative simulation compared to DSP applications. We also demonstrate the suitability of the DSP TMS...

Future database applications will require significant improvements in performance beyond the capabilities of conventional disk based systems. This paper describes a new approach to database systems architecture, which is intended to take advantage of solid-state memory in combination with data compression to provide substantial performance improvements. The compressed data representation is tai...

We describe the design and early implementation of an extensible, component-based software architecture for natural language engineering applications which interfaces with high performance distributed computing services. The architecture leverages existing linguistic resource description and discovery mechanisms based on metadata descriptions, combining these in a compatible fashion with other ...

The architecture and With the advent of fiber implementation presented distributed data interface in this paper are for the (FDDI) technology, Digital DEC FDDIcontroller 400, saw the need to define Digital's high-performance, an architecture for a XMI-to-FDDI adapter known high-performance adapter as DEMFA. This adapter that could transmit data provides an interface 30 times faster than between...

Many application domains (such as avionics, telecommunications, and multimedia) require real-time guarantees from the underlying networks, operating systems, and middleware components to achieve their quality of service (QoS) requirements. In addition to providing end-to-end QoS guarantees, applications in these domains must be flexible and reusable. Requirements for flexibility and reusability...

Providing end-to-end gigabit communication support for high-bandwidth multimedia applications requires transport systems that transfer data efficiently via network protocols such as TCP, TP4, XTP, and STII. This paper describes and classifies transport system services that integrate operating system resources such as CPU(s), virtual memory, and I/O devices together with network protocols to sup...

Traffic classification is critical to effective network control and management. Recent researches on Internet traffic classifications have developed several methods for identifying types of application, which have advantages in certain types of network traffic. However, these methods are powerless to measure the network traffic with dynamic port, encrypted payloads, mixing traffic, and real-tim...

The development of wavelength division multiplexing opens a new horizon in optical networks and promises to be one of the best solutions for the high demand of the bandwidth. However, with this technology, many problems arise, especially those related to the architecture to be used in optical networks to take advantage of the huge potential of this technique. Many approaches and architectures h...
