3.6 N-Intrinsics
ZSP_timer_stop(<timer>)
unsigned int ZSP_timer_read(<timer>)
The <timer> parameter must be TIMER0 or TIMER1. The <mode>
parameter must be SINGLE_SHOT or AUTO_RELOAD.
The following example illustrates how to use this interface to time a
section of code:
#include <stdio.h>
#include <timer_util.h>
main ()
{
}
N-Intrinsics provide support for DSP instructions. N-Intrinsics are
implemented as macros in the header file N_Intrinsic.h. The name
of an N-Intrinsic begins with an N_ , followed by a suffix that indicates the
operation’s data type: _s for int, _l for long, and _h for high-order int
of a long.
To use N-intrinsics, add the following line in each of your C files:
