RTOS/TMS320C6746: DSP/BIOS 5 Application to SYS/BIOS 6

Hi,

Converted Tcf file to cfg file .This need to be done manually even though command line command given.
I almost done that .While converting dsp bios to sys bios 6.46 below are some queries
1.
For g_ltf_msec = ( (float)CLK_CPUCYCLESPERLTIME() / (float)GBL_getFrequency() );

CLK_CPUCYCLESPERLTIME() and GBL_getFrequency which functions to be replaced in sys bios 6.46 . do I need to do changes in cfg file as well?

2. For CLK_getltime(); which function to be replace .Is modification in cfg file required. Do I need to include any file for this
I replaced CLK_getltime(); with Clock_getTicks(); .So in following statement instead of CLK_getltime(); I used Clock_getTicks
e.g. ta_f = ( (float)( Clock_getTicks() - t_1 ) * MULT_1000 * g_htf_msec );

Thanks

Manisha,

Clock_getTicks() is the correct replacement for CLK_getltime(). The default tick period for BIOS is 1ms. If your application requires a different tick period, add the following to your .cfg file:

    var Clock = xdc.useModule('ti.sysbios.knl.Clock');
    Clock.tickPeriod = 1000;  /* the tickPeriod is specified in microseconds */

The BIOS equivalent for GBL_getFrequency() is BIOS_getCpuFreq(). You must pass a ptr to Types_FreqHz structure to hold the return value:

    Types_FreqHz cpuFreq;

    BIOS_getCpuFreq(&cpuFreq);

    /* cpuFreq.lo contains the least significant 32 bits of the CPU frequency in Hz */
