embedded digital signal processors for baseband communication systems have stringent design constraints including high computational bandwidth, low power consumption, and low interrupt latency. Furthermore, these processors should be compiler-friendly, so that code for them can quickly be developed in a high-level language. this paper presents the design of a high-performance, low-power digital signal processor for baseband communication systems. the processor uses token triggered threading, SIMD vector processing, and powerful compound instructions to provide real-time baseband processing capabilities with very low power consumption. Using a super-computer class vectorizing compiler, the processor achieves real-time performance on a 2Mbps WCDMA transmission system.
Portable embedded devices must presently run multimedia and wireless network applications with enormous computational performance requirements at a low energy consumption. In these applications, the dynamic memory sub...

Ptolemy II [1] is a Java implemented modeling, simulation and code generation framework for heterogeneous, concurrent, real-time embeddedsystems. A key issue in the framework is correct and efficient execution of heterogeneous models of computation within a common simulator by using the object-oriented principles of polymorphism and information hiding.

In supply chain management, improving the efficiency of the overall supply chain is important. It has been found that sharing information between supply chain members can increase the efficiency of the supply chain by varying degrees in different situations. there are, however, many practical difficulties in sharing information with all the companies in a complex supply chain. this paper presents a multi-agent system for supply chain coordination where agents discover the structure of supply chains and share information on inventory levels only by local collaborations. Agents use the gathered information to estimate demands propagated from multiple markets through a complex network of companies with different lead times and market shares. the performance of the suggested system is investigated with a simulation experiment and the result is compared with an alternative strategy.
In this paper a new approach for an overall system design is presented. It supports object-oriented system modeling for software components in embeddedsystems in addition to time-discrete and time-continuous modeling...
