  • Coding for Neon - Part 3: Matrix Multiplication
    In part 1 of this series we dealt with how to load and store data with NEON, and part 2 involved how to handle the leftovers resulting from vector processing . Let us move on to doing some useful data...
  • 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...

  • 1-cycle multiply, 64-bit result,  reciprocal?
    Can someone tell me how many extra gates the 1-cycle multiply uses? If there was a 64-bit result, how many more gates would be used? Can these gates also be used to find the reciprocal of a number so...
