RELIANCE 57C429本地总线仲裁器本地总线仲裁程序实现固定优先级,如下表定时性能所述。本节提供了有关MVME162FX嵌入式控制器性能的信息。控制器设计为在25 MHz或32 MHz下工作。本地总线到DRAM周期时间DRAM基址、阵列大小和设备大小是可编程的。如果DRAM大小需要八个物理设备(即,当存储器阵列大小为4MB且DRAM技术为每个设备4 Mbits时;RELIANCE 57C429或当存储器阵列尺寸为16MB且DRAN技术为每个器件16 Mbits时),则DRAM控制器采用交错结构。奇偶校验和奇偶异常动作也可编程。DRAM阵列大小和设备大小在DRAM空间大小寄存器中初始化。RELIANCE 57C429
Local Bus Arbiter The local bus arbiter implements a fixed priority which is described in the following table Timing Performance This section provides information on the performance of the MVME162FX Embedded Controller. The controller is designed to operate at 25 MHz or 32 MHz. Local Bus to DRAM Cycle Times The DRAM base address, array size, RELIANCE 57C429and device size are programmable. The DRAM controller assumes an interleaved architecture if the DRAM size requires eight physical devices (that is, when the memory array size is 4MB and DRAM technology is 4 Mbits per device; or when the memory array size is 16MB and DRAM technology is 16 Mbits per device.) Parity checking and parity exception action is also programmable. The DRAM array size and device size are initialized in the DRAM Space Size Register.RELIANCE 57C429
