数据总线结构RELIANCE DSA-MTR-60D嵌入式控制器上的本地数据总线是基于MC68040总线的32位同步总线，支持突发传输和窥探。各种本地总线主设备和从设备使用本地总线进行通信。本地总线由优先级类型仲裁器仲裁。本地总线主机的优先级从高到低依次为：82596CA LAN、Industry Pack DMA、53C710 SCSI、VMEbus和MPU。一般来说，任何主机都可以访问任何从机；然而，RELIANCE DSA-MTR-60D并非所有组合都能通过常识测试。请参阅《MVME162FX嵌入式控制器程序员参考指南》和每个设备的用户指南，以确定其端口大小、数据总线连接以及访问设备时适用的任何限制。MC68040或MC68LC040 MPU在MVME162FX嵌入式控制器上使用MC680400或MC68LC 040处理器。MC68040具有片上指令和数据缓存、可选的高驱动器I/O缓冲区和浮点处理器。两个处理器之间的主要区别在于MC68040具有浮点协处理器。MC68040支持多主应用程序中的高速缓存一致性，具有专用的片上总线窥探逻辑。有关更多信息，请参阅MC68040微处理器用户手册。RELIANCE DSA-MTR-60D
Data Bus Structure The local data bus on the RELIANCE DSA-MTR-60DEmbedded Controller is a 32-bit synchronous bus based on the MC68040 bus, and which supports burst transfers and snooping. The various local bus master and slave devices use the local bus to communicate. The local bus is arbitrated by a priority type arbiter. The priority of the local bus masters from highest to lowest is: 82596CA LAN, Industry Pack DMA, 53C710 SCSI, VMEbus, and MPU. Generally speaking, any master can access any slave; however, not all combinations pass the common sense test. Refer to the MVME162FX Embedded Controller Programmer’s RELIANCE DSA-MTR-60DReference Guide and to the user’s guide for each device to determine its port size, data bus connection, and any restrictions that apply when accessing the device. MC68040 or MC68LC040 MPU The MC68040 or MC68LC040 processor is used on the MVME162FX Embedded Controller. The MC68040 has on-chip instruction and data caches, optional high drive I/O buffers, and a floating point processor. The major difference between the two processors is that the MC68040 has a floating point coprocessor. The MC68040 supports cache coherency in multi-master applications with dedicated on-chip bus snooping logic. Refer to the MC68040 Microprocessor User’s Manual for more information.RELIANCE DSA-MTR-60D
