Recently, the research of the PSO algorithm has gained more attention. The performance of the PSO algorithm can be improved by using hybrid techniques. In this paper, to solve the problem of slow convergence and optimize the PSO algorithm performance, we propose a new algorithm - cachereplacement Search PSO (CRS-PSO), which integrates basic PSO and the idea of cache design in the computer realm. The experimental results show that the proposed CRS-PSO can effectively solve the slow convergence problem and give a better performance than PSO alone.

In the recent times, various challenges are being encountered during SRAM cache design and development which lead to a situation of converting the memory cell technologies into on-chip embedded caches. The current research statistics towards cache designing reveals that Spin Torque Transfer Magnetic RAMs, preferably termed as STT-MRAMs has become one of the most promising areas in the field of memory chip design. Hence, it gained a lot of attention from the researchers due to its dynamic direct map and data access policies for reducing the average cost i.e. time and energy optimization. Instead of having efficient main memory access capability, STT-MRAMs suffer due to high error rate caused during stochastic switching in write operations. cache replacement algorithms play a significant role in minimizing the error rate in write operations. The proposed study aims to offer a theoretical and analytical modeling of an efficient cachereplacement scheme to overcome the error as mentioned above in L2-STT-MRAM caches. The performance analysis of the proposed algorithm ensures its effectiveness in reducing the error rate and cost overheads as compared to the conventional LRU technique implemented on SRAM cells.

cache memory helps in expediting the speed of data retrieval time in processors in heterogeneous multi-core architecture, which is the main factor that affects system performance and power consumption. The implementation algorithm of cachereplacement in current heterogeneous multi-core environment is thread-blinded, leading to a lower utilization of the cache. In fact, each of the CPU and GPU applications has its own characteristics, where CPU is responsible for the implementation of tasks and serial logic control, while GPU has a great advantage in parallel computing, which causes the need of cache blocks for CPU more sensitive than those for GPU. With that in mind, this research gives full consideration to the increment of thread priority in the cache replacement algorithm and takes a novel strategy to improve the work efficiency of last-level-cache (LLC), where the CPU and GPU applications share LLC dynamically and not in an absolutely fair status. Furthermore, our methodology switches policies between the LRU (Least Recently Used) and LFU (Least Frequently Used) effectively by comparing the number of cache misses on the LLC, which takes both the time and frequency of the accessing cache block into consideration. The experimental results indicate that this optimization method can effectively improve system performance.

A caching model is proposed to accelerate the I/O speed between disks and FPGA devices in the conditions of reconfigurable computing. Especially the speed of FPGA processing is much larger than the RAID reading rate. The accelerating strategy is based on LRU-MRU replacement, adding physical address factors at the same time. In the case of two-cache application mode, the accelerating strategy, according to the characteristics of FPGA application, can accelerate 5% comparing with the traditional LRU-MRU algorithm. Through the quantitative analysis of this algorithm, we propose the cache optimization model of small file to improve disk read rate for FPGA computation.

Video sharing system for mobile devices is an important mobile service which can be used to share videos with others. Scalability is critical to the system. cache technology, which employs cache servers to offload the original server, has been proposed to attack the scalability problem. Traditional replacementalgorithms for cache technology are not suitable for the video sharing system. In this paper, we proposed a cache replacement algorithm called S-LRU for the system. In S-LRU, we consider the size difference of videos. Experimental results demonstrate that S-LRU outperforms the other algorithms.

To improve the distributed cache replacement algorithm performance in wind power system, after researching several traditional algorithms such as LFU (Least Frequently Used), SIZE (Object Size Based), LRU (Least Recently Used) and Hybrid (Saved Value Based), a new algorithm FST (Frequency, Object size, Access time) is proposed. This algorithm combines the features of access frequency, object size, access time interval, and the longest time without access. It avoids the outdated "hot spots" document's occupying memory space to waste resources, so it is supposed to improve the system performance. By taking contrast test with LFU, SIZE and LRU in the wind power system cache server, FST algorithm shows better performance in request hit rate, byte hit rate and reducing delay time.
