Filter cache (FC) is effective in achieving energy saving at the expense of some performance degradation. The energy savings, here, comes from repeated execution of tiny loops from energy efficient FC. The absence of cacheable loops leads to performance degradation in such FC structures. Therefore, we propose a simple dynamic FC scheme, which detects the(More)
A filter cache is proposed at a higher level than the L1 (main) cache in the memory hierarchy and is much smaller. The typical size of filter cache is of the order of 512 Bytes. Prediction algorithms popularly based upon the Next Fetch Prediction Table (NFPT) helps making the choice between the filter cache and the main cache. In this paper we introduce a(More)
Energy dissipation in cache memories is becoming a major design issue in embedded microprocessors. Predictive filter cache based instruction cache hierarchy is effective in reducing the access energy substantially at the cost of certain performance degradation. Here, the energy-delay product reduction heavily depends on the prediction accuracy of the(More)
The power consumption of microprocessors has been increasing in step with the complexity of each progressive generation. In general purpose processors, this is primarily attributed to the high energy consumption of fetch and decode circuitry, pursuant to the high instruction issue rate required of these high performance processors. Predictive Decode Filter(More)
Speaker Verification is a memory and compute intensive process, giving rise to area and latency concerns in the way of its System-On-a-Chip implementation. The training schemes for computing the speaker models contribute significantly to the overall complexity in the implementation of the system. In this paper, we demonstrate that K-Means algorithm can be(More)
Potato peel is a waste biomass which can be a source of raw material for biofuel production. This biomass contains a sufficient amount of total reducing sugar (TRS), which can be extracted and further treated with microbial pathways to produce bioethanol. The extraction of TRS from potato peels by hydrolysis in dilute sulphuric acid was investigated at(More)
