MVME310 是MOTOROLA公司生产的一款VME总线工业级单板计算机。

MVME310 采用PowerPC处理器，具有较高的性能和可靠性，常用于国防和航空航天、工业自动化和医疗成像等领域。它支持VME总线标准，具有丰富的外设接口，包括串口、并口、网口等，同时具有较高的可扩展性，方便进行功能扩展和升级。

在计算机中，存储器的主要作用是存储程序和各种数据信息，并能在计算机运行过程中高速、自动地完成程序或数据的存取。

计算机的存储器通常包括内存储器和外存储器。MVME310 内存储器直接与运算器、控制器交换信息，容量体积小，存取速度快，一般只存放那些正在运行的程序和待处理的数据。MVME310 而外存储器通常以硬盘等形式表现而存在，作为内存储器的延伸，用来存放一些系统必须使用，但又不急于使用的程序和数据，这些程序和数据必须调入内存才能够执行。外存储器通常读取数据较慢，但容量大，可以长时间保存大量信息。

The MVME310 is a VME bus industrial-grade single-board computer produced by MOTOROLA.

With a PowerPC processor, the MVME310 offers high performance and reliability and is commonly used in defense and aerospace, industrial automation and medical imaging. It supports the VME bus standard, has a wealth of peripheral interfaces, including serial port, parallel port, network port, etc., and has high scalability, convenient for function expansion and upgrade.

In the computer, the main role of memory is to store programs and various data information, and can complete the access of programs or data at high speed and automatically during the operation of the computer.

The memory of a computer usually includes internal memory and external memory. The MVME310 internal memory directly exchanges information with the arithmetic device and the controller, the capacity is small, the access speed is fast, and generally only stores those programs that are running and the data to be processed. MVME310 External memory usually exists in the form of hard disk, as an extension of the internal memory, used to store some systems must be used, but not eager to use the programs and data, these programs and data must be transferred into the memory to be able to execute. External memory is usually slow to read data, but has a large capacity and can hold a lot of information for a long time.

Features:

Serial port connector · Four-channel DMA controller · Serial download from host computer

The Emerson/MOTOROLA MVME310 intelligent controller was used to develop prototypes of custom interfaces for VMEbus peripherals. It provides a large winding area; There are interrupt and DMA controller devices; In order to facilitate the development of the firmware, it is based on the MC68121 intelligent peripheral controller. The MVME310 provides two slots for a 16K byte wide dual-port static RAM buffer (4K is provided (bytes, two additional slots in the user area are available for buffer expansion) and twp slots for user programs up to 32K bytes in ROM/PROM. One socket can be configured with 8K bytes of static RAM. A PROM socket contains a 4K byte independent debugger -IPCbug. A serial port connector is also available.
