Embedded Processor based PPP Implementation for Globalstar Satellite Modem

DSP-Based Satellite CDMA Modem: A Low Complexity Implementation

This paper presents a reliable and low complexity scheme for acquisition, tracking and frequency offset recovery for a DSP-based satellite CDMA modem. An analysis of the performance, in terms of false alarm probability, detection probability and mean acquisition time, is carried out as a function of the complexity and the level of interference. The proposed scheme, based on a dedicated frame fo...

Implementation of a Co - Processor for Embedded

Embedded Implementation of VHR Satellite Image Segmentation

Processing and analysis of Very High Resolution (VHR) satellite images provide a mass of crucial information, which can be used for urban planning, security issues or environmental monitoring. However, they are computationally expensive and, thus, time consuming, while some of the applications, such as natural disaster monitoring and prevention, require high efficiency performance. Fortunately,...

Energy-Efficient Multi-processor Implementation of Embedded Software

This paper develops energy-driven completion ratio guaranteed scheduling techniques for the implementation of embedded software on multi-processor system with multiple supply voltages. We leverage application’s performance requirements, uncertainties in execution time, and tolerance for reasonable execution failures to scale processors’ supply voltages at run-time to reduce energy consumption. ...

Implementation and Evaluation of an SCA-Resistant Embedded Processor

Side-channel analysis (SCA) attacks are a threat for many embedded applications which have a need for security. With embedded processors being at the very heart of such applications, it is desirable to address SCA attacks with countermeasures which “naturally” fit deployment in those processors. This paper describes our work in implementing one such protection concept in an ASIC prototype and o...
