1.2.3. Memory barriers

To ensure a consistent memory view, it is architecturally defined that software must perform a Data Memory Barrier (DMB) operation:

  • between acquiring a resource, for example through locking a mutex or decrementing a semaphore, and making any access to that resource

  • before making a resource available, for example through unlocking a mutex or incrementing a semaphore

SWARM - Software ARM:
It is a modular simulation of an ARM 7 processor written in C++. It is cycle accurate, and models the datapath at the bus level. It is sufficiently complete that it will run microcontroller linux.

 SkyEye is an Open Source Software Project (GPL Licence). Origin from GDB/Armulator, The goal of SkyEye is to provide an integrated simulation environment in Linux and Windows. SkyEye environment simulates typical Embedded Computer Systems (Now it supports a series ARM architecture based microprocessors and Blackfin DSP Processor). You can run some Embedded Operation System such as ARM Linux, uClinux, uc/OS-II (ucos-ii) etc. in SkyEye, and analysis or debug them at source level.
