2.8.1. Overview of memory modelling with mapfiles

mapfile is a memory model which you can configure yourself. You can specify the size, access width, access type and access speeds of individual memory blocks in the memory system in a memory map file (see Map files).

ARMulator simulates each memory access as it occurs. It counts wait states according to the type of memory access.

The debugger internal variables $memstats and $statistics give details of accesses of each cycle type, regions of memory accessed and time spent accessing each region (see AXD and armsd Debuggers Guide for information on retrieving details of debugger internal variables).
