#include <nitro/os/systemCall.h>
void SVC_WaitByLoop( s32 count );
This function runs the loop process at the specified number of times on the system ROM.
Four cycles are needed for one loop. Normally, this makes it possible to reduce the number of times that the main processor stalls when a subprocessor has prior rights to the main memory, and the subprocessor is made to run a program on the system ROM.
There are times when it is effective to effect a call on the main processor side when it is necessary to give prior rights to the main processor for main memory display or other modes, but in most cases if operations are left to the cache or TCM, then there will not be any need to call the main processor.
