A system hierarchy for brain-inspired computing

Abstract: Neuromorphic computing draws inspiration from the brain to provide computing technology and architecture with the potential to drive the next wave of computer engineering1-13. Such brain-inspired computing also provides a promising platform for the development of artificial general intelligence14,15. However, unlike conventional computing systems, which have a well established computer hierarchy built around the concept of Turing completeness and the von Neumann architecture16-18, there is currently no generalized system hierarchy or understanding of completeness for brain-inspired computing. This affects the compatibility between software and hardware, impairing the programming flexibility and development productivity of brain-inspired computing. Here we propose 'neuromorphic completeness', which relaxes the requirement for hardware completeness, and a corresponding system hierarchy, which consists of a Turing-complete software-abstraction model and a versatile abstract neuromorphic architecture. Using this hierarchy, various programs can be described as uniform representations and transformed into the equivalent executable on any neuromorphic complete hardware-that is, it ensures programming-language portability, hardware completeness and compilation feasibility. We implement toolchain software to support the execution of different types of program on various typical hardware platforms, demonstrating the advantage of our system hierarchy, including a new system-design dimension introduced by the neuromorphic completeness. We expect that our study will enable efficient and compatible progress in all aspects of brain-inspired computing systems, facilitating the development of various applications, including artificial general intelligence.

An overview of message passing environments

Abstract: A majority of the MPP systems designed to date have been MIMD distributed memory systems. For almost all of these systems, message passing environments have provided the primary mechanism for programming multiprocessor applications. In this paper we provide an introduction to MPP systems in general. We then introduce current MPP message passing interfaces, by tracing their historical development over the last 10 years. In addition to their use within a single MPP architecture, we discuss the use of message passing systems to interconnect more loosely coupled processors in heterogeneous environments. Finally we review the development of ‘portability platforms’ — message passing systems that have been devised solely to allow portability of message passing programs between different systems.

The Inferno™ operating system

Abstract: The Inferno™ operating system facilitates the creation and support of distributed services in the new and emerging world of network environments, such as those typified by CATV and direct satellite broadcasting systems, as well as the Internet. In addition, as the entertainment, telecommunications, and computing industries converge and interconnect, different types of data networks are arising, each one as potentially useful and profitable as the telephone network. However, unlike the telephone system, which started with standard terminals and signaling, these new networks are developing in a world of diverse terminals, network hardware, and protocols. Inferno is designed so that it can insulate the diverse providers of content and services from the equally varied transport and presentation platforms. The Inferno Business Unit of Lucent Technologies and the Computing Sciences Research Center of Bell Labs, the R&D arm of Lucent, designed it specifically as a commercial product. It is intended for licensing in the marketplace and for use in conjunction with new Lucent offerings. Inferno incorporates many years of Bell Labs research in operating systems, languages, on-the-fly compilers, graphics, security, networking, and portability in providing an effective and economical network operating system.

Android-based mobile educational platform for speech signal processing

Abstract: With the purpose of further mastering and grasping the course of speech signal processing, a novel Android-based, mobile-assisted educational platform (AEPS) is proposed in this paper. The goal of this work was to design AEPS as an educational signal-processing auxiliary system by simulating signal analysis methods commonly used in speech signal processing and bridging the gap for transition from undergraduate study to industry practice or academic research. The educational platform is presented in a highly intuitive, easy-to-interpret and strongly maneuverable graphical user interface. It also has the characteristics of high portability, strong affordability, and easy adoptability for application extension and popularization. Through adequate intuitive user interface, rich visual information, and extensive hands-on experiences, it greatly facilitates students in authentic, interactive, and creative learning. This paper details a subjective evaluation of AEPS’s effectiveness as an educational tool. The re...
