cache system的音標為:[k??? s??s?st?m]
基本翻譯為“緩存系統”。
速記技巧:將“cache”拆分為“ca”和“chache”,其中“ca”可以理解為“藏”,“chache”意為存儲的東西,結合起來就是“藏東西的地方”,即“緩存系統”。
Cache system這個詞的英文詞源可以追溯到拉丁語“cachet”和“cachinnus”,意為“隱藏”或“嘲笑”。它的變化形式包括復數形式“caches”,過去式和過去分詞形式“cached”或“cached”,現在分詞形式“caching”等。
相關單詞:
1. Caching(緩存):這是cache system的核心概念,指的是將數據存儲在更接近用戶或更快速的位置,以減少訪問時間。
2. Secondary cache(二級緩存):相對于主存儲器,例如RAM,二級緩存通常指更小、更快、成本更低的存儲設備,如高速RAM或SSD。
3. Cache hit(緩存命中):在緩存系統中,當數據在緩存中可用時,稱為緩存命中。這通常意味著性能提升,因為數據可以從更快的緩存中獲取,而不是從慢速的主存儲器中獲取。
4. Cache miss(緩存未命中):當數據不在緩存中時,稱為緩存未命中。這可能需要從主存儲器中獲取數據,導致性能下降。
5. Cache coherence(緩存一致性):這是緩存系統中的一個重要概念,確保多個處理器或線程不會同時修改同一數據,從而導致數據不一致。
6. Cache optimization(緩存優化):這是為了提高緩存性能和效率而進行的技術和策略。
7. Cache memory(緩存存儲器):通常是指用于存儲常用或頻繁訪問的數據的小型快速存儲設備。
8. Cache hit rate(緩存命中率):衡量緩存系統性能的一個重要指標,表示實際緩存命中的次數占總訪問次數的比例。
9. Cache hit latency(緩存命中延遲):指從數據請求到數據被實際返回的時間。它對系統性能有重要影響,因為較短的延遲通常意味著更好的性能。
10. Cache size(緩存大小):決定緩存系統能夠存儲的數據量。它需要根據應用需求和系統性能進行權衡和管理。
常用短語:
1. cache memory
2. cache hit
3. cache miss
4. cache buffer
5. cache replacement policy
6. cache coherency
7. cache hierarchy
例句:
1. The cache memory is designed to improve system performance.
2. We need to improve the cache hit rate to reduce the number of disk accesses.
3. The cache buffer is full, so we need to replace some entries.
4. The cache replacement policy should be carefully chosen to ensure optimal performance.
5. We need to ensure that all processors are working in harmony to maintain cache coherency.
6. The cache hierarchy should be optimized for the specific workload to achieve maximum efficiency.
英文小作文:
Cache systems are essential components of modern computing systems, which help improve performance by storing frequently used data in a more accessible and efficient manner. Caches are typically composed of a buffer memory that stores recently used data, along with a replacement policy that determines which data should be discarded in favor of new entries. The cache hierarchy refers to the entire system of caches, which can include levels of different sizes and speeds, all working together to maximize efficiency and minimize latency.
Cache systems are crucial for high-performance computing, as they allow for faster access to data, reducing the number of disk accesses and improving overall system performance. However, maintaining cache coherency and ensuring that all processors are working in harmony is a challenging task that requires careful design and implementation. As computing systems continue to evolve, cache systems will continue to play an increasingly important role in ensuring optimal performance and high-efficiency operation.
