EC_relocateXScratchMem
Description
Changes the X scratch memory buffer used by the AEC algorithm.
Include
ec_api.h
Prototype
void EC_relocateXScratchMem(int* ptrStateX, int* xScratchMem);
Arguments
ptrStateX
xScratchMem
a pointer to the state memory for this instance of AEC
a pointer to the new X scratch memory to be used by the AEC
algorithm
Return Value
None.
Remarks
After relocating the X scratch memory, the older scratch memory is not used by the
AEC library.
Code Example
int ecStateMemX [EC_XSTATE_MEM_SIZE_INT]
int ecScratchX [EC_XSCRATCH_MEM_SIZE_INT]
int ecScratchX2 [EC_XSCRATCH_MEM_SIZE_INT]
int ecScratchY [EC_YSCRATCH_MEM_SIZE_INT]
_XBSS(2);
_XBSS(2);
_XBSS(2);
_YBSS(2);
.
.
.
EC_init(ecStateMemX, ecScratchX, EC_ORDER);
The AEC algorithm is using ecScratchX for its scratch memory.
.
.
.
EC_relocateXScratchMem(ecStateMemX, ecScratchX2);
The AEC algorithm is now using ecScratchX2 for its scratch memory.
