ARM7 printf long long int

Hi, my program does not do the expected things, printf a unsigned long long int. #include <aduc7026.h> #include"stdio.h" void RS232_init(void); int main (void) { unsigned long long int A; RS232_init...

ARM v8 Neon instruction for multiply long

Hi All, I need perform multiply long operation on uint16x8_t data type on ARM v8. The ARM v7 implementation would be as follows: uint16x8_t u16x8_data1 = vld1q_u16(pBuffer1); uint16x8_t u16x8_data2...

Any NEON instructions can be dual issued with vector long multiply accumulate (SMLAL) on Cortex A53 or A55?

Anyone know if this is possible? I've tried several instruction mixes: A53 A55 smlal.int8 & 64bit load (ld1) 0.97 1.72 instructions/cycle smlal.int8 & 64bit dup 0.97 0.96 smlal.int8 & 64bit or...
