How to get M3's cpu loading and memory usage?

Hi,

I use TI 816x evm and RDK 01.05.00.08.

My question is how to get cpu loading and memory usage on each M3 processor?

Is there any utility can print out these message?

Thank you very much!

    The M3 cpu loading can be print out at function Utils_prfLoadPrintAll() of Utils_prf.c.

        Vps_printf("\r\n");
        Vps_printf(" %d: LOAD: CPU: %d%% HWI: %d%%, SWI:%d%% \n", Clock_getTicks(),

                   cpuLoad, hwiLoad, swiLoad);

    What is the mean about hwiLoad and swiLoad?

    Hi,

    HWI load means CPU load in interrupt. How much processing is done in interrupt, SWI load means processing done in software interrupt. BIOS supports some software interrupts also. And CPU load is the cumulative load of hardware interrupt, software interrupt and task context. For all practical purpose CPU load is enough to notice.

    Hi Medwin

    The heap status also can be print out by send command "SYSTEM_COMMON_CMD_PRINT_STATUS".

    You can get this print message:

        Vps_printf
            (" %d: SYSTEM  : Heap Free Space (System = %d bytes, FrmBuf = %d bytes,
             BitBuf = %d bytes, Mbx = %d msgs) \r\n",
             Clock_getTicks(), Utils_memGetSystemHeapFreeSpace(),
             Utils_memGetBufferHeapFreeSpace(),
             Utils_memGetBitBufferHeapFreeSpace(),
             Utils_mbxGetFreeMsgCount());
