Radio Astronomy with RASDR2

The RASDR design team is releasing a software-defined receiver (SDR) for radio astronomy called RASDR2 7 . The receiver consists of two high-density circuit boards -a wide-band femtocell 8 chip on the front end analog interface MyriadRF board 9 linked to a DigiRed digitization and function control board -coupled to a computer via either a USB2 or USB3 interface. RASDRViewer software runs in a W...

Cancellation of GLONASS signals from Radio Astronomy Data

Astronomers use the 1612 MHz OH spectral line emission as a unique window on properties of evolved stars, galactic dynamics, and putative proto-planetary disk systems around young stars. In recent years, experiments using this OH line have become more difficult because radio telescopes are very sensitive to transmissions from the GLONASS satellite system. The weak astronomical signals are often...

Partition-Based Hardware Transactional Memory for Many-Core Processors

Transactional memory is an appealing technology which frees programmer from lock-based programming. However, most of current hardware transactional memory systems are proposed for multi-core processors, and may face some challenges with the increasing of processor cores in many-core systems, such as inefficient utilization of transactional buffers, unsolved problem of transactional buffer overf...
