Recent advances in computer arithmetic offer interesting alternative solutions for low-power design. Depending on an assortment of factors that need to be considered, it is worth evaluating the logarithmic number system (LNS) or the residue number system (RNS) for hardware implementations of computationally intensive tasks. As such, the choice of arithmetic can lead to substantial power savings.

The Multimodal Bio-Medical systems Workshop (MBM) was held on October 22 in Maryland and it focused on challenges for multimodal bio-medical systems. The workshop was initiated by life sciences and physical sciences experts to identify and highlight new computational paradigms and technology infrastructure in biomedicine owing to recent advance in biosciences and instruments. The workshop targeted both the micro/nano level and the macro level of biomedical systems. This invitation workshop brought together a selected group of about 40 worldclass experts in the areas of biology, engineering and public and exnvironmental health for a full-day interaction and discussion in the Lister Hill Auditorium.

In this paper, we study the performance of a prioritized on-board baseband switch in conjunction with a multibeam satellite handling integrated services. The services considered for the analysis include voice, video, file transfer and interactive data. The prioritized switch uses both input and output buffering, switch speed-up as well as a two-phase head-of-line resolution algorithm, in order to reduce the buffer loss while maintaining acceptable user delays. The minimum required buffer capacity and switch speed-up for each service in a prioritized environment are found under uniform traffic conditions. It is shown that under uniform traffic conditions, only minimal buffering and switch speed-up are needed even for the lowest priority users. The performance dependence on the switch size is also substantially reduced with head of line resolution and buffering even in a prioritized environment.
