MVME134 Motorola 单板计算机  嵌入式计算机控制器

MVME134是摩托罗拉的一款单板计算机，其中包含MC68020微处理器和MC68881协处理器。

MVME134主要功能有：

前面板运行、停止和故障状态LED。

前面板复位和中止开关。

通过边缘连接器P2远程重置。

五位软件可读标题；模块状态寄存器（MSR）的一部分。

单板计算机是构建在单个电路板上的完整计算机，具有微处理器，存储器，输入/输出（I/O）以及计算机所需的其他功能。

MVME134单板计算机被制作为演示或开发系统，用于教育系统或用作嵌入式计算机控制器。许多类型的家用计算机或便携式计算机将其所有功能集成到单个印刷电路板上。与台式个人计算机不同，单板计算机通常不依赖于扩展插槽来实现外围功能或扩展。MVME134单板计算机使用各种微处理器构建。简单的设计，例如由计算机爱好者构建的设计，通常使用静态RAM和低成本的8或16位处理器。其他类型（例如刀片服务器）的性能与服务器计算机类似，只是采用更紧凑的格式。

MVME134输入/输出（I/O）是指计算机与外部设备或数据源之间的数据传输。输入是指从外部设备或数据源向计算机传输数据，而输出是指从计算机向外部设备或数据源传输数据。I/O操作可以是同步的或异步的，这取决于程序的需求和外部设备的特性。在编程中，I/O操作通常由特定的I/O函数或系统调用执行。

The MVME134 is a single-board computer from MOTOROLA that contains the MC68020 microprocessor and the MC68881 coprocessor.

The main functions of MVME134 are:

Front panel run, stop and fault status LED.

Front panel reset and abort switch.

Remote reset via edge connector P2.

Five-digit software-readable title; Part of the module Status Register (MSR).

A single-board computer is a complete computer built on a single circuit board, with a microprocessor, memory, input/output (I/O), and other features required for a computer.

The MVME134 single board computer is manufactured as a demonstration or development system, for use in educational systems or as an embedded computer controller. Many types of home computers or portable computers integrate all of their functions onto a single printed circuit board. Unlike desktop personal computers, single-board computers generally do not rely on expansion slots for peripheral functionality or expansion. The MVME134 single-board computer is built using a variety of microprocessors. Simple designs, such as those built by computer enthusiasts, typically use static RAM and low-cost 8 - or 16-bit processors. Other types, such as blade servers, perform similarly to server computers, but in a more compact format.

MVME134 Input/Output (I/O) refers to the transfer of data between a computer and an external device or data source. Input refers to the transfer of data from an external device or data source to a computer, while output refers to the transfer of data from a computer to an external device or data source. I/O operations can be synchronous or asynchronous, depending on the requirements of the program and the characteristics of the external device. In programming, I/O operations are usually performed by a specific I/O function or system call.
