Study on the low power cache design technique 設(shè)計(jì)技術(shù)的研究
In the memory access subsystem design, on the basis of deeply discussing three kernel problems encountered in cache design, this paper presents a li cache model with virtual index and physical tag, using a hardware-based method to solve the synonym problem, and adopting l2 cache " s initiative requesting for the li cache " s snoop service to keep the consistency between li cache and l2 cache, then takes li data cache as an example to illustrate the li cache implementation 在訪存子系統(tǒng)的設(shè)計(jì)中,深入研究并解決了cache設(shè)計(jì)中的三個(gè)核心問題:采用虛地址索引、實(shí)地址tag,用硬件方式解決synonym問題,以l2cache向l1cache主動(dòng)請(qǐng)求snoop服務(wù)的方式實(shí)現(xiàn)兩級(jí)cache間的一致性。在此基礎(chǔ)上,給出了一個(gè)l1d-cache原型。
