单片机SINGLE-CHIP MICROCOMPUTER(中文14000字,英文9500字,英文PDF)
摘要
一个单片机，包括处理器，计算过程的控制单元和操作执行单位。微机还包括一个内存单元，接口，缓冲存储单元，一个单元来控制通过系统传输的信息交换。所有这些单位和处理器，其计算过程的控制单元和操作执行单位双向总线互连。该处理器还包括一个缓冲存储单元，处理器信息交换控制单元，地址比较器，这都是相互联系的。单片机还包含了总线仲裁器和连接到单位控制通过系统传输的信息交换系统行仲裁者。最后，微机系统线连接到处理器和缓冲存储单元的地址比较。单片机根据本发明，可以组合成一个系统，一个共同的记忆领域。
单片机发明背景
1．发明的范围
本发明涉及数字计算机，更特别的，一个单片机。最好是适用于提供高效率的多处理器计算系统的一个共同的记忆领域的发明。本发明也适用于过程控制系统和数控机床。

ABSTRACT
A single-chip microcomputer comprises a processor incorporating a computation process control unit and an operation execution unit. The microcomputer further comprises a memory unit, an interface, a buffer storage cell, and a unit to control exchange of information transmitted through a system line. All these units and the processor with its computation process control unit and operation excution unit are interconnected by a bidirectional bus. The processor also includes a buffer storage cell, a processor information exchange control unit, and an address comparator, which are all interconnected. The single-chip microcomputer further contains a bus arbiter and a system line arbiter which are connected to the unit to control exchange of information transmitted through the system line. Finally, the microcomputer includes a system line address comparator connected to the processor and buffer storage cell. The single-chip microcomputer according to the invention can be combined into a system with a common memory field.
