Most embedded systems have limited amount of memory. In contrast, the memory requirements of code (in particular loops) running on embedded systems is significant. This paper addresses the problem of estimating the amount of memory needed for transfers of data in embedded systems. The problem of estimating the region associated with a statement or the set(More)
Compact code generation is very important for an embedded system that has to be implemented on a chip with a severely limited amount of size. Even though on-chip data memory optimization technique has been given more attention, on-chip instruction memory optimization should not be neglected. We propose in this paper some algorithms for a memory offset(More)
The EPC network, a de facto standard of RFID network, provides a variety of services including Information Service (IS) and Discovery Service (DS), fully utilizing today's Internet capabilities, such as HTTP or SOAP communication protocols and HTML or XML contents formats. The mobile RFID network exploits the existing cellular network infrastructure and(More)
This paper describes an efficient mechanism for multicast tree reconstruction at source mobility in a source specific multicast (SSM). Source mobility makes its address changed so that the existing multicast tree corresponding to the home of address (HoA) of the mobile source should be rebuilt. But this causes a large amount of packet delay during the(More)
Clock selection has a significant impact on the performance and quality of designs in high-level synthesis. In most synthesis systems, a convenient value of the clock is chosen or exact (and expensive) methods have been used for clock selection. This paper presents a novel heuristic approach for near-optimal clock selection for synthesis systems. This(More)
Ubiquitous wireless Internet access is to connect all devices to the Internet at any time and any place. To achieve this ubiquitous wireless Internet, we consider integrating the Internet and mobile ad-hoc networks. One of the most important issues in ubiquitous wireless Internet access is to find an efficient and reliable Internet gateway. We propose a(More)
Applications based on geographical location are increasing rapidly in wireless sensor networks (WSN). Localization algorithm research has drawn wide attention in recent years and brought about many sophisticated algorithms. The majority of localization algorithms can be divided into range-free or range-based, based on whether they use range information.(More)
Most embedded systems have limited amount of memory. In contrast, the memory requirements of the digital signal processing (DSP) and video processing codes (in nested loops, in particular) running on embedded systems is significant. This paper addresses the problem of estimating and reducing the amount of memory needed for transfers of data in embedded(More)
An important class of problems used widely in both the embedded systems and scientific domains perform memory intensive computations on large data sets. These data sets get to be typically stored in main memory, which means that the compiler needs to generate the address of a memory location in order to store these data elements and generate the same(More)
