چکیده

This paper presents preliminary results on the design of an Object Coprocessor (OCP) cooperating with a RISC– architecture processor (ARM7, by Advanced RISC Machines Ltd.). This coprocessor implements in hardware some low–level processing and control steps required by the object–oriented model. The processor and the OCP constitute a processing architecture whose extended instruction set features “object” treatment capabilities. Some special coprocessor instruction codes (“Object Instructions”) have been introduced. Concepts such as “Polymorphism” and “Virtual methods” are supported at the hardware level. Preliminary results using typical object–oriented sequences show a gain in speed over a pure software implementation, on the same RISC machine. The specific design presented here refers to a prototype implementation that is currently under development and supported by the European Union Esprit Project (7517 SUMIS).

Analysis of Hardware and Software Approaches to Embedded In-Circuit Emulation of Microprocessors

This paper investigates various approaches to embed the functionality of in-circuit emulation (ICE) into microprocessor cores in SoC (System-On-Chip) chips. Three styles of ICE’s (hardware-oriented, software-oriented and hybrid) are defined and implemented. They are integrated with a synthesizable ARM7 microprocessor core and synthesized to gate level to quantitatively analyze and compare their...

Declarative Semantics in Object-Oriented Software Development - A Taxonomy and Survey

One of the modern paradigms to develop an application is object oriented analysis and design. In this paradigm, there are several objects and each object plays some specific roles in applications. In an application, we must distinguish between procedural semantics and declarative semantics for their implementation in a specific programming language. For the procedural semantics, we can write a ...

Objects Identification in Object-Oriented Software Development - A Taxonomy and Survey on Techniques

Analysis and design of object oriented is onemodern paradigms for developing a system. In this paradigm, there are several objects and each object plays some specific roles. Identifying objects (and classes) is one of the most important steps in the object-oriented paradigm. This paper makes a literature review over techniques to identify objects and then presents six taxonomies for them. The f...

On Attributes of Objects in Object-Oriented Software Analysis

One of the modern paradigms to develop a system is object oriented analysis and design. In this paradigm, there are several objects and each object plays some specific roles. There is a sequence of activities to develop an analysis model. In the first step, we work in developing an initial use case model. Then in the second step, they identify a number of concepts and build a glossary of partic...
