simd

I have some code in a loop

for(int i = 0; i < n; i++)
{
  u[i] = c * u[i] + s * b[i];
}

So, u and b are vectors of the same length, and c and s are scalars. Is this code a good candidate for vectorization for use with SSE in order to get a speedup?

What's the difference between logical SSE intrinsics?

Hello, Is there any difference between logical SSE intrinsics for different types? For example if we take OR operation, there are three intrinsics: _mm_or_ps, _mm_or_pd and _mm_or_si128.

Combining prefixes in SSE

as seen on Stack Overflow - Search for 'Stack Overflow'
In SSE the prefixes 066h (operand size override) 0F2H (REPNE) and 0F3h (REPE) are part of the opcode. In non-SSE 066h switches between 32-bit (or 64-bit) and 16-bit operation. 0F2h and 0F3h are used for string operations. They can be combined so that 066h and 0F2h (or 0F3h) can be used in the… >>> More
