Part Number: TMS320F28388D
We have used function as :
void memcpy_asm(void * dst, const void * src, UINT16 u16Length)
{
asm( " LSR AL, #1\n");
asm( " DEC AL\n" );
asm( " MOV AR0, AL\n");
asm( " MOVL ACC,*XAR5++\n"
" MOVL *XAR4++,ACC \n"
" BANZ -2,AR0--\n");
}
UINT16 XorChecksum_asm(void *vptrData, UINT16 u16Length)
{
asm( " DEC AL\n" );
asm( " MOV AR0, AL\n");
asm( " MOV ACC, #0\n");
asm( " RPT AR0 || XOR ACC, *XAR4++\n");
}
My question is when parameters are passed, how AL, XAR4, XAR5 are filled with data of passed parameters ?. Which PDF will give me information about this ?
I was referring " TMS320C28x Optimizing C/C++ Compiler v18.1.0.LTS". But no where its mentioned UINT16 data is stored in AL, FIrst void * parameter, second void * parameter in so and so register.
Can I get details from where I could get data ?.
