In this paper, we review the file formats for data storage in radio astronomy. As a standard format used in astronomy, Flexible Image Transport System (FITS) is discussed firstly. Random Group FITS File (UVFITS) and FITS Interferometry Data Interchange (FITS-IDI) based on FITS are highlighted. And VOTable promoted by the development of Virtual Observatory (VO) is also briefly reviewed. We all know...
Development of semiconductor technology has led to advent of complex digital systems, such as portable, embedded, SoCs, and FPGA devices. Complexity of modern applications and deep-submicron technologies make low-power design attitude compulsory. The higher the level of abstraction of a design that power optimizations are applied, the higher are potential savings. Memory is known to be extremely power...
Software-based self-test (SBST) is increasingly used for testing processor cores embedded in SoCs, mainly because it allows at-speed, low-cost testing, while requiring limited (if any) hardware modifications to the original design. However, the method requires effective techniques for generating suitable test programs and for monitoring the results. In the case of processor core testing, a particularly...
In this paper a BISR architecture for embedded memories is presented. The proposed scheme utilises a multiple bank cache-like memory for repairs. Statistical analysis is used for minimisation of the total resources required to achieve a very high fault coverage. Simulation results show that the proposed BISR scheme is characterised by high efficiency and low area overhead, even for high defect densities...
