[Discuss-gnuradio] max and argmax blocks with SIMD instructions

[Trond Danielsen]

Hi everyone,

I've written a couple of blocks for GNU Radio, but am not satisfied
with the performance. I am therefore thinking of using SIMD
instructions. However, I am not that familiar with x86 assembly
instructions, and finding the reference manual on Intel's website was
not easy. I know that DSPs such as the Blackfin has special vector
instructions that would make this very simple, but I am not sure about
x86.

I am also going to write a general purpose multiply and accumulate
block that would benefit much from SIMD instructions.

Any comments are appreciated.
