• 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...
  • Cortex M0/M0+/M1 32-bit x 32-bit --->64-bit signed multiply
    I have been spent about 2 months trying to find a faster way of multiplying 2 32-bit numbers giving a 64-bit result. It is truly driving me mad because it FEELS like their is a faster solution. I should...
  • Bit-Banding. Only 1 bit at a time?
    Hi, I am developing a fixed-point MP3 & ACELP decoder on an Arduino Due. I realize that bit-banding makes a RMW sequence atomic but I notice fields in the Due hardware are multi-bit fields. Is there an...

  • How many ways to set a register 32 bit value?
    Hi, I find Arm has 16 bit immediate value load to register instruction, but it has no instruction to load 32 bit value to register. I am new to asm level programming. How many ways to load a register...
