Does anyone know how to determine the memory usage of different processes and how much is available? Also, how can the CPU usage be determined?
GreenHills Multi2000 has a good tool to view the state of the OS. It includes dialogues for all threads, timers, semaphores and so on…
To measure the CPU load I use a very low priority thread and let it run full speed just incrementing an integer. then every 10 seconds I check how high it counted. The higher it counts, the less load on the cpu. To determine the maximum it will count to at 0 load, let it be the only thread and just see how high it goes. Hope this helps
To find out memory-usage I do a loop with allocating memory in blocks of 256 K. When malloc() fails, i approximatly know how much is available. After that don’t forget to free all memory blocks again
