2014年11月25日 · A TLB has a fixed number of slots that contain page table entries, which map virtual addresses to physical addresses. It is typically a content-addressable memory (CAM), in which the search key is the virtual address and the search result is a physical address.

The TLB lets the processor very quickly convert virtual addresses to physical addresses. If an instruction asks the processor to do some memory operation on a (virtual) address, the processor first checks to see whether the TLB contains an entry for that virtual address.

2016年4月19日 · The TLB is a cache that holds (likely) recently used pages. The principle of locality says that the pages referenced in the TLB are likely to be used again soon. This is the underlying idea for all caching. When these pages are needed again, it takes minimal time to find the address of the page in the TLB.

2018年7月13日 · Instead, the TLB only maintains mappings for the pages that are accessible to the current process. If process A is currently running, the TLB only contains mappings for the pages that are accessible to process A; so if page 2 belongs to process B, it won't be in the TLB. Also, you should be aware that the TLB is a cache.

2011年7月23日 · You may have to tweak the code in qemu to print the contents of TLB. Look at tlb_* functions in qemu/exec.c You may want to add a tlb_dump_function to print the contents of the TLB. As far as I know, this is the closest you can get to dumping the contents of TLB. P.S: I started answering this question and then realized it was an year old.

2015年10月7日 · #import "MyComponents.tlb" no_namespace named_guids IComponentXYZ *pComponent; Sometimes when I right-click on IComponentXYZ in the .h file and "Go to declaration", a MyComponent.tlh file is displayed which shows me the COM wrapper definitions. But other times, it says no definition exists. Can I manually open this file in Visual Studio?

2019年8月17日 · TLB miss occurs when the page table entry required for conversion of virtual address to physical address is not present in the TLB(translation look aside buffer). TLB is like a cache, but it does not store data rather it stores page table entries so that we can completely bypass the page table in case of TLB hit as you can see in the diagram.

2011年4月3日 · I was convinced that there is no way to find COM dependencies of an ActiveX but to my surprise OLEVIEW shows some comments Like: // TLib : // TLib : OLE Automation : {00020430-0000-0000-C000-

2017年5月20日 · A TLB (Translation Lookaside Buffer) is a cache of the translations from virtual memory addresses to physical memory addresses. When a processor changes the virtual-to-physical mapping of an address, it needs to tell the other processors to invalidate that mapping in their caches. That process is called a "TLB shootdown".

2019年1月8日 · Apparently, regtlibv12.exe is part of Visual Studio 2010 (contrary to what I read on various Microsoft forums), but it is located in the Windows\Microsoft.NET\Framework\v4.0.30139 folder (not the v2.0.50727 folder). Using that executable I was able to successfully register the legacy typelib (.tlb).
