[Discuss-gnuradio] GMSK Gaussian filter byte alignment?

2007-10-31 Thread George Nychis
Hey all, I've been playing around with GMSK and reading through the code of the processing blocks. I see that the dot product code for the Gaussian filter is optimized such that it requires the data be 16-byte aligned. Where does this alignment actually occur in the processing chain? On the

This and other questions. You are not doing something right. Just using the spe's for fft's we will see a huge speed up in gnuradio. I can run filter, NCO, baud clock and carrier recovery, and equalizer on the cell on 40 Mbaud signals. Trying getting that out of a (Intel) cola nut. We
