寄存器

Accumulator and index register can be accessed by the programmer.

序员可以对累加和变址寄存进行存取。

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.

首先,使用了一个串入并出移位寄存“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.

一协同序访问指令，该指令把栈顶弹入临时寄存，把序计数推入栈，然后把保存的栈顶容存入到序计数。
