Hardware and software for intelligent robotic systems

A hardware and software methodology for the design of the three interactive levels of intelligent robotic systems is proposed. The organization level is modeled as an expert system, the coordination level as a loosely coupled parallel processing system and the execution level as a series of specific hardware components which execute specific tasks. Microprocessor-based configurations and discrete logic design techniques are utilized for the overall system hardware configuration. The proposed methodology, does not violate the system hierarchical structure. A case study demonstrates the feasibility of the approach.

Handling advanced scheduling heuristics under a hardware compiler generation environment

The complexity of modern digital systems requires complex design entry methods and thus, language based designs are often an appealing alternative for schematics. Language based design entry, supports high-level design transformations through formal and executable traditional compiler construction problem specifications, their main advantages being modularity and declarative notation. In this paper, this idea is exploited under a powerful compiler construction system and a methodology is given to design formal and executable high-level hardware manipulators. In effect, this methodology stands as a meta-level between hardware transformations and their implementation and can be valuable in fast evaluation of new ideas and techniques.

Integration of heterogeneous CAD databases using STEP and the Internet

In a large-scale design process, designers cooperate in a complex situation where a variety of software tools run on different hardware platforms. This paper presents a data enhancement approach to integrate heterogeneous Computer-Aided Design (CAD) databases through the Internet. The data enhancement means topological changes in a geometric model and additional information in design semantics. The geometric data is enhanced using a non-manifold modeler to produce data sets valuable in downstream applications such as a Finite Element Method (FEM) solver or a detail design system. As a practical example, a shipbuilding product model database has been implemented based on the Standard for the Exchange of Product (STEP) model data methodology and shipbuilding features. The system has been implemented on a network environment that consists of a Web browser, Common Object Request Broker Architecture (CORBA) objects, a relational database management system, a data enhancement module, and various computer-aided applications.

A relational database machine with large semiconductor disk and hardware relational algebra processor

This paper describes the basic concepts, design and implementation decisions, standpoints and significance of the database machine Delta in the scope of Japan’s Fifth Generation Computer Project. Delta is planned to be operational in 1985 for researchers’ use as a backend database machine for logic programming software development. Delta is basically a relational database machine system. It combines hardware facilities for efficient relational database operations, which are typically represented by relational algebra, and software which deals with hardware control and actual database management requirements. Notable features include attribute-based internal schema in accordance with the characteristics found in the relation access from logic programming environment. This is also useful for the hardware relational algebra manipulation algorithm based on merge-sorting of attributes by hardware and a large capacity Semiconductor Disk for fast access to databases. Various implementation decisions of database management requirements are made in this novel system configuration, which will be meaningful to give an example for constructing a hardware and software combination of a relational database machine. Delta is in the stage between detailed design and implementation.
