[Discuss-gnuradio] Problem with adopting ccomplex_dotprod_sse() in my block

2007-03-14 Thread hanwen
Hi, everyone, Recently, I'm implementing some synchronization algorithm in block, which require higher efficiency. I try to use the function ccomplex_dotprod_sse() to speed up the block, but I always get "segment fault". I'm using a PC with Pentium D CPU, and I'm sure the ccomplex_dotprod_sse() w
