Short for Level 2 cache, L2 cache, secondary cache, or external cache, L2 is specialized, high-performance computer memory on the die of the CPU (Central Processing Unit). Unlike Layer 1 cache, L2 cache was on the motherboard on earlier computers, although with newer processors it is ...
You may observe that CPU cache is always supported by the label L1, L2, L3, and occasionally even L4. These labels indicate the multilevel cache utilized for CPUs. So, L1 would be tier one, L2 is tier two, and L3, obviously, is tier three. L1is the fastest memory found in any co...

Level 1 Cache:L1 cache is usually integrated into the CPU chip and offers the highest speed. The CPU accesses L1 cache most frequently. Level 2 Cache:L2 is located between the CPU and the RAM and larger than the L1 cache, but slower. The CPU accesses L2 when required data isn't found...
Level 2 cache Level 2 (L2) is also called the “secondary cache.” It’s where your computer goes when it can’t find your data (or gets a “miss”) after looking in the L1 cache. Level 2 is usually on a memory card in close proximity to the processor. ...
causing the printer to mix output by sending data while some other user's file is printing.不使用系统资源(CPU、磁盘空间); 在其他用户的文件正在打印时,通过发送数据,使打印机混合输出。 b. Probably not, since any protection scheme for time-sharing environment devised by a human can also be broke...

Some dependent libraries attempt to automatically detect the L2 cache size of the system in order to optimize performance. Runtime environments ofFunction Computeare strongly isolated sandbox environments. The L2 cache size cannot be specified. Even it is configured, the specified L2 cache size doe...

But what happens when there's a cache miss? It takes a long time to fetch data from main memory, and while that's happening the CPU is just sitting there idle. So someone had the idea to basically have two sets of thread state (PC + registers) so that another thread (maybe in the...
