Compiler/TDA4VM: How to make clock_create using the kernal Clock to create SW Interrupts?

I didn't get your question. Clock_create() already creates SW Interrupts. You want to know how to configure the BIOS clock ? like for example tickPeriod ?

Take a look at section 5.2 of the BIOS user guide

5.2 Clock
The ti.sysbios.knl.Clock module is responsible for the periodic system tick that the kernel uses to keep
track of time. All SYS/BIOS APIs that expect a timeout parameter interpret the timeout in terms of Clock
ticks.
The Clock module, by default, uses the ti.sysbios.hal.Timer module to create a timer to generate the
system tick, which is basically a periodic call to Clock_tick(). See Section 5.3 for more about the Timer
module.
The Clock module can be configured not to use the timer with either of the following configuration
statements:
The period for the system tick is set by the configuration parameter Clock.tickPeriod. This is set in
microseconds.
The Clock_tick() and the tick period are used as follows:
• If the tickSource is Clock.TickSource_TIMER (the default), Clock uses ti.sysbios.hal.Timer to
create a timer to generate the system tick, which is basically a periodic call to Clock_tick(). Clock
uses Clock.tickPeriod to create the timer. Clock.timerId can be changed to make Clock use a different
timer.

I have read the chapter5.2, It said if clock_create will use HW Timer by default.

If I use this example below, if it means the clock.create will create SW Interrupt?

var Clock = xdc.useModule('ti.sysbios.knl.Clock');
var clockParams = new Clock.Params();
clockParams.period = 5;
clockParams.startFlag = true;
clockParams.arg = (UArg)0x5555;
Program.global.clockInst1 = Clock.create("&myHandler1", 5, clockParams);

Yes, clock_create() uses the same HW Timer which is also used by BIOS for it's tick.

Your code will create a SW interrupt.
