I\'m a little confused by the meaning of \"Aliasing\" between CPU-cache and Physical address. First I found It\'s definition on Wikipedia :
I found a way to read L1(data and instruction) cache using http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.faqs/ka4237.html.
Is taskset for CPU affinity applicable when trying to use L2 cache efficiently 开发者_Go百科on a multi core processor in a virtualised environment like Amazon EC2?No, especially towards the smaller in
How do I find the cache block size in Ubuntu, programmatically (with C++) or开发者_开发知识库 otherwise?You can find it in /proc/cpuinfo; cache size for the total size, and cache_alignment for the blo
Recently I was reading some material on cpu cache. I am wondering how does the cpu lookup the L1 and L2 cache and in what format is the data in the cpu cache stored?
Is it possible to read CPU开发者_开发问答 cache hit/miss rate in Android?According to the developer docs, you can use android.os.Debug.startNativeTracing() to get information about cache misses, if yo
I am trying to understand the principles of machine code alignment. I have an assembler implementation which can generate machine code in run-time. I use 16-bytes alignment on every branch destination
I am trying to understand how CPU cache is operating. Lets say we have this configuration (as an example).
there\'re a lot of buzz about cache-related performance issues. I have several questions about them: Probably most popular issues are cache locality, and false cache sharing. Any others?
It appears that CPUs run significantly faster if their L2 is not filled. Will a progr开发者_StackOverflow社区ammer be better off to code something that will eventually be smaller in binary, even if pa
