Remember that a CPU's cache is local (on-chip) memory that offers fast access over the system's memory.

记住CPU缓存是一个本地(片上)内存，提供了比系统内存更快的访问能力。

To speed up address translation, there is a processor-on-a-chip (PoC) cache and associated logic called translation lookaside buffer (TLB).

为了加快地址转换，架构中有一个 processor-on-a-chip (PoC)缓存和相关的转换后备缓冲器 (TLB)逻辑。

Due to the latency difference between main memory and on-chip memory cache, POWER7 was designed with three levels of on-chip cache (see Figure 1).

由于主内存和芯片级内存缓存之间的延迟差别，POWER 7设计了三种级别的芯片级缓存机制(见图1)。

One major feature of the Power 780 is TurboCore technology, which gives you the option to run the system with fewer cores to take advantage of increased cache from other cores on the chip.

Power 780的主要特性之一是TurboCore技术，这种技术允许用更少的核运行系统，从而利用芯片上的其他核增加缓存。
