Mapping Memory
If you are using the emulator in ACT mode, emulation memory cannot be
used; therefore, this section is not applicable.
Because the emulator can use target system memory or emulation memory
(or both) in Normal mode, it is necessary to map ranges of memory so that
the emulator knows where to direct its accesses.
Up to 8 ranges of memory can be mapped, and the resolution of mapped
ranges is 256 bytes (that is, the memory ranges must begin on 256-byte
boundaries and must be at least 256 bytes in length).
Emulation memory is made available to the mapper in 64-Kbyte blocks.
When you map an address range to emulation memory, at least one block is
assigned to the range. When a block of emulation memory is assigned to a
range, it is no longer available, even though part of the block may be unused.
Direct memory access (DMA) to emulation memory is not permitted.
You should map all memory ranges used by your programs before loading
programs into memory.
In order to map memory, you must first start the configuration interface and
access the "Memory Map" configuration section (refer to the previous "Using
the Configuration Interface" section).
