I'm looking now into incorporating some simd instructions into my code.
How ever the following SIMD code
nm_srl_pi32(sy,13)
Is much much slower then
sy>>13

Any ideas?
Thanks
Aviv

Aviv,

Thanks for your interest in the forum. Unfortunately the PXA product line was sold to Marvell over a year ago. You can see details here: http://software.intel.com/en-us/forums/showthread.php?t=54050

If you would like support for this line of products, you might look at http://www.marvell.com/products/cellular/index.jsp

Thanks,
Lester
