Hi.
I wonder how to calculate absolute value of a 32-bit signed integer in C as fast as possible. I saw that there is a FPU instruction VABS.F32, which do that in one cycle (above the floats). I thought, if it is possible to use it also with integers …
Why the Cortex M4 instruction SMMUL (32 = 32 x 32b) preserves a redundant sign bit and discards one useful bit of information? What could possibly be the justification for such blatant disregard of the ISO/IEC TR 18037 standard Fract format?
I need to be able to handle long bitfields as effectively as possible. Right now I need up to 64 bits in length.
Are there instructions to set, clear and test individual bits in one cycle available for some of the architectures? Which? Particularly, will…
I need some indications to begin writing a program.
Write a compare routine to compare 64-bits values , using only two instructions.
Thanks for your indications !
Hello I was curious about which ARM launch/starter board would be best used to create an electronics controller for a 32 bit 3D FDM printer? I was thinking that I've seen one project for the TI TM4C123G launchpad that might work. But are there better…
