Hi all, I've been working on ARM platforms and supporting VOLK for a while now, and I've wanted to support accelerating Android (and therefore Java) as devices become smaller and lower power. The obvious answer to accelerating this code is to take advantage of ARM's Jazelle mode which is direct

No, my hypothesis is that backpressure from the USRP (meaning: the OFDM Mapper block can't write samples to its output) leads to GNU Radio having to drop messages between OFDM MAC and OFDM Mapper. That backpressure could simply be caused by you producing more samples per second than the USRP

On the release 4 image, you can't set the clock speed under 10 MHz. However, you can use a DDC (which is built in and automatically used). Simply set the clock rate to 32 MHz (or 16 MHz if this is MIMO) and the sample rate to 8 MHz. Cheers, Martin On 03/30/2016 05:02 PM, Gabriel Pechiarovich
