一般來說，ALSTOM NRD108028 8RDB43655 SA43655.E任何主設(shè)備都可以訪問任何從設(shè)備；然而，并非所有組合都能通過“常識測試”。請參閱《單板計(jì)算機(jī)程序員參考指南》和每個(gè)設(shè)備的用戶指南，以確定其端口大小、數(shù)據(jù)總線連接以及訪問設(shè)備時(shí)適用的任何限制。ALSTOM NRD108028 8RDB43655 SA43655.E
M88000 MPU 基于M88000系列，使用一個(gè)MC88100 MPU和兩個(gè)MC88200或MC88204 CMMU。一個(gè)CMMU用于數(shù)據(jù)緩存，一個(gè)用于指令緩存。有關(guān)更多信息，請參閱MC88100和MC88200用戶手冊以及MC88204數(shù)據(jù)表。ALSTOM NRD108028 8RDB43655 SA43655.E
EPROM用于27C102JK或27C202JK型EPROM的四個(gè)44針PLCC/CLCC EPROM插座。他們是：? 組織在兩個(gè)32位寬的庫中，支持8位、16位和32位讀取訪問? 由VMEchip2控制? 本地總線復(fù)位后映射到本地總線地址0–這允許MC88100在復(fù)位后開始在地址0執(zhí)行代碼。ALSTOM NRD108028 8RDB43655 SA43655.E
英文資料：
In general, any master can access any slave; however, not all combinations pass the “common sense test.” Refer to the Single Board Computers Programmer's Reference 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.ALSTOM NRD108028 8RDB43655 SA43655.E
M88000 MPU The is based on the M88000 family and uses one MC88100 MPU and two MC88200 or MC88204 CMMUs. One CMMU is used for the data cache and one is used for the instruction cache. More information is available in the MC88100ALSTOM NRD108028 8RDB43655 SA43655.E and MC88200 user's manuals and the MC88204 data sheet.
EPROM Four 44-pin PLCC/CLCC EPROM sockets for 27C102JK or 27C202JK type EPROMs. They are: ? Organized in two 32-bit wide banks supporting 8-, 16-, and 32-bit read accesses ? Controlled by the VMEchip2 ? Mapped to local bus address 0 following a local bus reset – This allows the MC88100 to start executing code at address 0 following a reset.ALSTOM NRD108028 8RDB43655 SA43655.E
