寄存器

Accumulator and index register can be accessed by the programmer.

程序员可以对累加器和变址寄存器进行存取。

The first method is that a series connection-input and parallel connection-output macrocell of register “74164” is adopted,which divides one part of data stream into two parts.

,用了一个串并出移位寄存器“74164”宏单元,将一路数据流分成两路。

A coroutine call instruction.The instruction pops the top of stack into temporary register, pushes program counter onto the stack, and then puts the saved top of stack in the program counter.

一协同程序访问指令，该指令把顶弹临时寄存器，把程序计数器内，然后把保存的顶内容存到程序计数器内。
