Figure 3.58 Address Translation according to VP_MAP Tables

How to translate addresses depends on the settings of the radio buttons of the memory area group

in the [Configuration] dialog box. The following shows how to translate addresses in each setting

state.

•

When the Normal radio button is selected:

The VP_MAP table has a priority over the TLB. When the VP_MAP table is enabled and the

specified address is within the VP_MAP table settings, the emulator translates the address

according to the VP_MAP table. If the specified address is outside the VP_MAP table settings

even when the VP_MAP table is enabled, or when the VP_MAP table is disabled, the emulator

translates the address according to the MMU state.

•

When the Virtual radio button is selected:

The address is translated according to the TLB. If the specified address is outside the TLB

table settings, a TLB error will occur.

•

When the Physical radio button is selected:

The address is not translated.
