  • An adaptive algorithm for sensor activation in renewable energy based sensor systems 

    Mereddy, Sandeep Reddy; Jaggi, Neeraj; Pendse, Ravi (IEEE, 2009-12-07)
    Future sensor networks would comprise of sensing devices with energy harvesting capabilities from renewable energy sources such as solar power. A key research question in such sensor systems is to maximize the asymptotic ...
  • An algorithm for the two dimensional FFT 

    Hoyer, E.A.; Berry, W. (IEEE, 1977-05-01)
    Conventional two dimensional fast Fourier transforms become very slow if the size of the matrix becomes too large to be contained in memory. This is due to the transposition of the matrix that is required. This new algorithm ...
  • A novel graphical technique for analysis of runtime cache behavior 

    Pendse, Ravi; Tambe, N.; Walterscheidt, U. (IEEE, 1997-08-06)
    A novel technique is introduced to graphically analyze the runtime behavior of block replacement algorithms used in cache controllers. The new method allows a behavioral comparison of two or more algorithms, previously ...
  • Phase synchronization for distributed sensor networks in feedback bit errors 

    Wu, Haijie; Ding, Yanwu; Kwon, Hyuck M. (IEEE, 2010-06-25)
    It has been reported recently that phase synchronization in distributed sensor networks can be achieved by adjusting the phase in sensors randomly with a single bit feedback from the receiver (base station) to the sensors. ...
  • Pipeline LRU block replacement algorithm 

    Bhagavathula, Ravi; Chittoor, P.; Pendse, Ravi (IEEE, 2000)
    Recent advances in VLSI technology have spurred a tremendous increase in the performance of processors. Due to the slower main memory, there exists a bottleneck in the performance of computer systems. Caching is an effective ...
  • Timing analysis of block replacement algorithms on disk caches 

    Rajamoni, R.; Bhagavathula, Ravi; Pendse, Ravi (IEEE, 2000)
    Cache memories are used to reduce the memory latency in systems. While instruction references of a CPU exhibit high temporal and spatial locality, disk references exhibit very minimal temporal and spatial locality. Owing ...
