清单3演示了未初始化内存的概念，这是用.bss部分指令(第14行)定义的。
Listing 3 illustrates the concept of uninitialized memory, defined using the.bss section directive (line 14).
代码压缩技术通过对整个应用程序全部或者部分指令进行压缩，能够有效地减少内存的尺寸、功耗等。
Through Compressing full code or sub code of application software, the code compression technology can reduce the size and power of the memory effectively.
在SPU上，大部分指令都可以在寄存器上进行操作，就仿佛它们分别包含多个无关的值一样(因此可以对多个数据项执行一条指令)。
On the SPUs, most instructions can operate on registers as if they contained multiple, independent values (thus the single instruction acting on multiple data items).
模拟器不得不为 guest-kernel-to-application通信拦截大部分指令，也不得不模拟一组完整的虚拟硬件设备。
The emulator has to intercept most of the instructions used for guest-kernel-to-application communications and has to model a complete set of virtual hardware devices.
