2.产 品 详 情 资 料：
RELIANCE SA3000DC70如果基板上填充了4MB，那么兼容的mezzanies是从4开始的。（即，夹层地址映射从4MB开始。）因此，在4MB基板上，夹层上的内存似乎与基板上的内存相邻。软件可以通过检查偏移地址$25处的寄存器的第七位（位23）来确定基板上有多少内存。该位在MC2芯片初始化时由硬件状态机设置。《MVME162FX嵌入式控制器程序员参考指南》中MC2芯片编程模型中的DRAM内存控制器部分规定了内存性能。下表定义了用于控制器SRAM选项的基板和夹层内存填充选项的组合。RELIANCE SA3000DC70嵌入式控制器的设计包括512KB SRAM选项。SRAM架构是单非交织的。其性能在《RELIANCE SA3000DC70嵌入式控制器程序员参考指南》中MC2芯片编程模型中的SRAM内存控制器一节中进行了规定。
RELIANCE SA3000DC70If the base board is populated with 4MB, the compatible mezzanines are ones that start at four. (i.e. the mezzanine address map starts at 4MB.) Therefore on 4MB base boards, the memory on the mezzanine appears contiguous to the memory on the base board. The software can determine how much memory is on the base board by examining the seventh bit (bit 23) of the register at offset address $25. This bit is set upon MC2 chip initialization by a hardware state machine. Memory performance is specified in the section on the DRAM Memory Controller in the MC2 chip Programming Model in the MVME162FX Embedded Controller Programmer’s Reference Guide. The following table defines the combinations of base board and mezzanine memory population options used for the controller SRAM Options The MVME162FX Embedded RELIANCE SA3000DC70Controller’s design includes a 512KB SRAM option. SRAM architecture is single non-interleaved. Its performance is specified in the section on the SRAM Memory Controller in the MC2 chip Programming Model in the MVME162FX Embedded Controller Programmer’s Reference Guide.RELIANCE SA3000DC70
