缓存器的容量 - Register File 寄存器 << Cache 缓存器 (SRAM) << Main Memory 内存 (DRAM)。 缓存器的延迟 - Register File 寄存器 << Cache 缓存器 (SRAM) << Main Memory 内存 (DRAM)。 缓存器的带宽 一般来说,缓存器和处理器是在同一块片上系统的(On-Chip),然后,内存和处理器不在,所以,从带宽...
为了解决这个问题,Kroft提出了non-blocking cache,(aka lookup-free cache, aka out-of-order-memory system),如下图所示: non-blocking cache 其实就是在cache miss之后,cpu继续发送load/store指令;那么我们可能会有hit after miss,也可能有miss after miss,甚至多次miss连续发生。 我们来看看我们需要增加哪些结构...
Cache存储器(Cache Memory)使得计算机看似拥有了比实际更多的快速存储器。存储器应该具有非易失性(non-volatile)、廉价、快速、功耗低的特点。在现实世界中,每种存储技术都有其自身的特点,其中有些特点是相互矛盾的。例如,速度快的存储器往往昂贵,而速度慢的存储器往往便宜。存储系统使用了几种不同的技术,每种技术...
Synonyms COMA (Cache-only memory architecture) Definition A Cache-Only Memory Architecture (COMA) is a type of cache-coherent nonuniform memory access (CC-NUMA) architecture. Unlike in a conventional CC-NUMA architecture, in a COMA, every shared-memory module in the machine is a cache, where...
The Java Pool Advisor statistics provide information about library cache memory used for Java and predict how changes in the size of the Java pool can affect the parse rate. The Java Pool Advisor is internally turned on when statistics_level is set to TYPICAL or higher. These statistics reset...
Definition A Cache-Only Memory Architecture (COMA) is a type of cache-coherent non-uniform memory access (CC-NUMA) architecture. Unlike in a conventional CC-NUMA architecture, in a COMA, every shared-memory module in the machine is a cache, where each memory line has a tag with the line...
We will also show the performance savings that arise from the use of a large next-generation L2 cache. 展开 关键词: SRAM chips cache storage fault tolerance memory architecture 3D stacking technology MRAM PRAM RRAM SRAM fault resilient set associative cache architecture ...
4 The Memory Management Unit (MMU) 内存管理单元 (MMU) 执行地址翻译。MMU 包含以下内容: The table walk unit : 它从内存中读取页表,并完成地址转换 Translation Lookaside Buffers (TLBs) : 缓存,相当于cache 软件看到的所有内存地址都是虚拟的。 这些内存地址被传递到 MMU,它检查最近使用的缓存转换的 TLB。
Disclosed is an instruction-level method and system for prefetching data or instructions of variable size to specified cache sets. A prefetch instruction containing binary fields allows the compiler,
