Vega处理器包含了一个客户化的读屏障指令，它具有字段检查元数据和针对GC压缩页面的特殊的虚拟内存保护。
Vega processors included a custom read barrier instruction that included bit field checking in reference metadata as well as special virtual memory protection for GC-compacted pages.
Giesler提出一种理论认为，瘙痒感在STT神经元里面产生一种兴奋的状态，而搔痒可以抑制这种状态——好像是我们的手指给脊髓神经元发指令让它们冷静下来。
Giesler theorizes that the itch sensation creates an excited state in the STT neurons that scratching inhibits - as if our fingernails were sending a message to spinal-cord neurons to cool off.
查平说：“如果你想要机器人臂向左动，你就得找携带向左运动指令的那小撮神经元。”
"If you wanted to have a robot arm move left," Chapin explains, "you would have to find that small set of neurons that would carry the command to move to the left."
为了便于获取指令，处理器把需要的由二元数据构成的地址存储在外部处理机总线的序列里面。
To carry out a fetch, the processor places the binary-code address of the desired location onto the address lines of the external processor bus.
使用元数据，运行时可以访问加载代码并将其处理为本机指令所需的所有信息。
Using metadata, the runtime has access to all the information it needs to load your code and process it into native machine instructions.
