Memory Management
All system memory resides on the MCP-IPx card. Random Access Memory (RAM) is
located directly on the MCP-IPx card. The MCP-IPx also acts as a mother card to baby
CLA and DBX memory cards. The DBX contains 1MB of Static Random Access
Memory (SRAM) expansion memory.
Flash memory, located on the IMC8 card, stores the generic feature software which
determines the operation of the system. RAM, both on the MCP-IPx and on the DBX
expansion cards, stores the system configuration database, and is used as a run
memory for general purposes.
Database memory and real-time clock functions in the Coral system are protected
against power loss by long-life lithium backup batteries. A battery is installed both on
the MCP-IPx and on each DBX card. A monitoring circuit on each card constantly
measures the voltage level of its battery. It signals the main processor when the
remaining energy stored in any battery approaches the point that it can no longer
provide sufficient power to maintain the memory circuitry.
The generic feature software and feature authorization information is installed and
updated into the IMC8 using FMprog PC-utility. Similarly, the system database is
regularly backed up to, and may be transferred and restored from, an IMC8 card kept
in the IMC8 drive.
The Program Interface Facility
The PI (Program Interface) and CoralVIEW CVA/CVD provides a text-based facility
for reviewing and changing the system configuration and database. It enables the
performance and monitor of diagnostic routines. The PI can be accessed either via a
simple data terminal or by a personal computer.
The PI and CoralVIEW CVA/CVD/CVT can be accessed via an RS-232E data terminal
port (KB0) provided on the MCP-IPx front panel (see
Figure 8-3
), or via an additional
RS-232E ports (KB1, KB2, KB3) provided at the top left of the IPx 500M main cage via
the Auxiliary connector. See
