ICS TRIPLEX T9402冗余控制模块，T9402使用指导

内存配置默认值。动态RAM夹层板的默认配置将使用从使用ENV参数“的基址”选择的地址开始的最大内存大小动态内存”。基址参数默认为0。较小的夹层将紧跟在内存映射中较大的上方。如果相同尺寸和类型的夹层存在时，第一个（最靠近电路板）映射到选定的基址。如果夹层存在相同大小但不同类型（奇偶校验和ECC），奇偶校验类型将映射到随后是选定的基址和ECC类型的夹层。

Memory Configuration Defaults.

The default configuration for Dynamic RAM mezzanine boards will position the mezzanine with

the largest memory size to start at the address selected with the ENV parameter "Base Address of

Dynamic Memory". The Base Address parameter defaults to 0. The smaller sized mezzanine will

follow immediately above the larger in the memory map. If mezzanines of the same size and type

are present, the first (closest to the board) is mapped to the selected base address. If mezzanines of

the same size but different type (parity and ECC) are present, the parity type will be mapped to the

selected base address and the ECC type mezzanine will follow. The SRAM does not default to a

location in the memory map that is contiguous with Dynamic RAMENV asks the following series of questions to set up the VMEbus interface for the MVME172

series modules. You should have a working knowledge of the VMEchip2 as given in the

MVME172 VME Embedded Controller Programmer’s Reference Guide in order to perform this

configuration. Also included in this series are questions for setting ROM and Flash access time.

The slave address decoders are used to allow another VMEbus master to access a local resource of

the MVME172LX. There are two slave address decoders set. They are set up as follows:Configuring the IndustryPacks

ENV asks the following series of questions to set up IndustryPack modules

(IPs) on MVME172LXs.

The MVME172 VME Embedded Controller Programmer’s Reference

Guide describes the base addresses and the IP register settings. Refer to

that manual for information on setting base addresses and register bits. Introduction

This chapter describes the MVME172LX VME embedded controller on a

block diagram level. The Description of Features provides an overview of

the MVME172LX, followed by a detailed description of several blocks of

circuitry. Figure 4-1 shows a block diagram of the overall board

architecture.

Detailed descriptions of other MVME172LX blocks, including

programmable registers in the ASICs and peripheral chips, can be found in

the MVME172 Embedded Controller Programmer’s Reference Guide

(part number VME172A/PG). Refer to it for a functional description of the

MVME172LX in greater depth.
