直接映射的cache是指每个cache块可以包含一个且只有一个主存块。这种类型的cache可以被快速搜索,但是由于它是1:1映射到内存位置,因此hit rate很低。介于这两个极端之间的是n-way associative cache。2-way associative cache(Piledriver的L1是2-way)意味着每个主内存块可以映射到两个cache块中的一个。8-way意味着...

The goal of the cache system is to ensure that the CPU has the next bit of data it will need already loaded into cache by the time it goes looking for it (also called a cache hit). A cache miss, on the other hand, means the CPU has to go scampering off to find the data elsewh...
I have designed line 66 to perfectly cache. If you comment out line 64, you will see the L1 read gets 100% L1 cache hit rate. HOWEVER, when these reads are interleaved as is in the unmodified code, I only get a 15.8% L1 hit rate. If the .cg instruction really is avoiding the L1...
Design structure for autonomic mode switching for l2 cache speculative accesses based on l1 cache hit rate.A design structure of a speculative access mechanism in a memory subsystem monitors hit rate of an L1 cache, and autonomically switches modes of speculative accesses to an L2 cache ...
Solved: Hello, everyone: I am a new user of Intel Vtune. I want to measure the L1 and L2 cache miss rate on intel Quad 4 Q6600 processor. The
An appropriate cache strategy will improve the cache hit rate.\r\n Read-data && Write-data: Caches both read-data and write-data.\r\n Read-data Only: Caches read-data only.\r\n Write-data Only: Caches write-data only. 战略: 选择将贮藏什么样的数据。 一个适当的贮藏所战略将改进高速...
It is exactly the same amount as the rate increased. However, the stall cycle increased significantly. So, the L2 bound increased due to L2 cache stall cycle, rather than due to increased L2 hit ratio. Finally, these are my questions. Why is the stall cycle increasi...

Cache是一种特殊的存储器,它由Cache 存储部件和Cache控制部件组成。Cache 存储部件一般采用与CPU同类型的半导体存储器件,存取速度比内存快几倍甚至十几倍。而Cache 控,21ic电子技术开发论坛
