Parameter | Type | Values |

ace_mode | Boolean | true or false. |
This statement enables the ACE mode if the CHARON-AXP license permits it. If this statement is omitted from the CHARON-AXP configuration file and the license permits it, "true" is the default, otherwise "false" is the default. For test purposes the ACE mechanism can be disabled with:

The CHARON-AXP log file displays the status of the ACE option.
The ACE mode is disabled when the host system does not meet the minimum physical requirements for this operation. If the emulator appears to not run at its normal performance, check the log file for a change in the ACE mode and verify that sufficient host resources, especially memory, are available.
The ACE mode can be additionally calibrated with "set ace" directive and the following parameters:
Parameter | Type | Description | |
|---|---|---|---|
| cpu_architecture | Text String | Specifies the architecture of the virtual Alpha CPU. Can be one of the following: EV4, EV45, EV5, EV56, EV6, EV67, EV68 Example:
Refer to this section to find an appropriate value of the HP Alpha architecture per each HP Alpha model supported by CHARON-AXP. | |
cache_size | Value | "cache_size" defines the amount of memory in megabytes allocated to the ACE cache. The default value of the cache_size set to 1GB (1024 MB). Example:
|
RAM
The CHARON-AXP memory subsystem is permanently loaded and has the logical name "ram".
| Parameter | Type | Description |
|---|---|---|
| size | Numeric | Size of the emulated memory in MB. |

It is important to have the "system_name", "hw_model", "cpu_architecture" and "dsrdb[n]" (DSRB - Dynamic System Recognition Data Block) parameters in sync. (see above for details) to configure CHARON-AXP to for emulation of a particular HP Alpha model.
The following table illustrates tables illustrate how to synchronize those values:
