The filter weights are designed to optimize the contrast resolution performance of the imaging system.  ...  We previously described a beamformer architecture that replaces the single apodization weights on each receive channel with channel-unique finite impulse response (FIR) filters.  ...  The authors thank IBM for their Shared University Research Program and access to the high performance computing cluster as well as members of UVa's Research Computing Support Team.  ...

In this work we propose a method to explore the design space for implementing a reliable multi-mode system.  ...  Wide range of digital systems from wireless devices to multi-media terminals are characterized by their multi-mode behavior. Many of these systems are deployed in high-radiation environments [5].  ...  SYSTEM ARCHITECTURE This section discusses the architectural details of the system guarding the FIR filters.  ...
