这条指令本身是基于位的,因此所有类型都使用相同的底层指令。
The instruction itself is bit-based, so all types use the same underlying instruction.
信道是一个32位的区域,通过使用特殊指令可被重写或读取(但不可能二者兼备——它们是无方向的)。
A channel is a 32-bit area which can be written to or read from (but not both — they are unidirectional) using special instructions.
实际上,内存地址对于任何指令格式可以使用的最大长度只有24位!
In fact, the largest length available for a memory address to any instruction format is only 24 bits!
