The Processor and Main Memory

Motherboard is the main computer circuit inside the PC, which holds the processor, memory and expansion slots, and connects directly or indirectly to every part of the PC.

主板是电脑中主要的电路板，其上安有处理器、内存和扩展槽，并直接或间接地与电脑各个部件相连。

The existing JMM says that volatile reads and writes are to go directly to main memory, prohibiting caching values in registers and bypassing processor-specific caches.

现有 JMM 表明易失性的读和写是直接和主存打交道的，这样避免了把值存储到寄存器或者绕过处理器特定的缓存。

Data may be moved between registers, processor caches, and main memory in different order than specified by the program.

数据可能在寄存器，处理器缓冲区和主内存中以不同的次序移动，而不是按照程序指定的顺序。
