In this paper, we explore 6 SPM allocation algorithms to improve performance or energy efficiency for Hybrid SPM-Cache (HSC) architectures, including 4 heuristic-based algorithms and 2 optimal algorithms based on model checking. Our experimental results show that the Greedy Stack Distance based Allocation for Energy (GSDA-E) algorithm can efficiently minimize the energy consumption and achieve near...
Hardware co-processors are used for accelerating specific compute-intensive tasks dedicated to video/audio codec, encryption/decryption, etc. Since many of these data-processing tasks already have efficient software algorithms, one could reuse those to synthesize the co-processor IPs. However, such software algorithms are usually sequential and written in C/C++. High-level Synthesis (HLS) helps in...
Aiming at the limited resources and data transmission redundancy of WSN, this paper proposes a novel data compression algorithm based on lifting wavelet transform, gives the rational design. The algorithm distributes the computing quantity which the lifting wavelet transform requires to all nodes, eliminates extra computing and data transmission, reduces the information redundancy of network, greatly...
