SOFTWARE RADIO IN CELL PHONES

SEMINAR ON SOFTWARE RADIO IN CELL PHONES : The memory hierarchy of high performance and embedded processors has been proved to be one of the largest consumer of energy. By extrapolating current trends, this Party is likely to increase in the near future. In this paper, a technique proposed using an additional mini cache, called L0-cache, located between the I-cache and the CPU core. This mechanism could provide useful information about the location Stream and, when managed properly, can effectively eliminate the need for high I-cache more expensive. Five techniques are proposed and evaluated that are used for dynamic behavior analysis to the instructional program and proactively guide-L0 cache. The basic idea is that only the most played part of the code are stored in L0 cache, because this is where the program spends most of his time. The results of experiments show that over 60% of the energy dissipated and The cache subsystem can be saved.
