#include <nitro/os.h>
void IC_PrefetchRange( const void* startAddr, u32 nBytes );
startAddr | Lowest address in the prefetch region |
nBytes | Number of bytes in the prefetch region |
None.
This function prefetches the instruction code of the specified region into the instruction cache.
startAddr
is rounded down to the closest 32-byte boundary. startAddr
+ nBytes
is rounded up to the closest 32-byte boundary.
Operates register 7 of the system control coprocessor. This function divides the specified range into cache-line units and repeats its operation. Thus the amount of time it takes is proportional to the size of the range.
IC_InvalidateRange, IC_LockdownRange
11/14/2005 Changed the type of startAddr
to const void*
.
04/19/2005 Added a description of the reason why processing time is proportional to the size of the memory region.
12/22/2003 Initial version.
