The frontend stalls caused by instruction and BTB misses are a significant source of performance degradation in server processors. Prefetchers are commonly employed to mitigate frontend bottleneck. However, next-line prefetchers, which are available in server processors, are incapable of eliminating a considerable number of L1 instruction misses. Temporal instruction prefetchers, on the other hand, effectively remove most of the instruction and BTB misses but impose significant area overhead. Recently, an old idea of using BTB-directed instruction prefetching is revived to address the limitations of temporal instruction prefetchers. While this approach leads to prefetchers with low area... 

One of the primary factors affecting the amount of worldwide energy consumption and greenhouse gas emissions is cooking. Solar cooking is an appropriate solution because it is both inexpensive and expandable. To illustrate modern advancements and the current status of solar cooking technology, this paper presents a review of recent experimental and analytical socioeconomic studies on solar cookers. The experimental studies have been divided into three categories based on different solar cooker structures: (i) box types, (ii) concentrating types, and (iii) panel types. Next, different designs are investigated according to their direct or indirect heat transfer modes and optional equipment for...
