start of the "run" signal. This is important for MIMO. Bug reported by Christoph Hein and Hanwen .
2009-09-03seems to build a decent fpga, but still some issues with a full connection.Matt Ettus

2009-07-30Add custom FPGA build.jcorgan
This is a custom build for USRP2 FPGA. It allows using a BasicRX or LFRX board and feed two independent, real signals. In addition, instead of the CIC/HB decimator, which optimizes frequency response, it uses an integrate and dump decimator, which optimizes for time-domain impulse response. These changes have been made in dsp_core_rx.v: * A second DDC has been added, sharing a frequency register with the existing DDC. * The output of the two DDCs are interleaved as I1 Q1 I2 Q2I ... into the receive FIFO. This limits the host configured decimation to 8 intead of 4. Use gr.deinterleave to recover the streams. * The ADCs are hardcoded: RX_A ==> DDC #1 I-input 0 ==> DDC #1 Q-input RX_B ==> DDC #2 I-input 0 ==> DDC #2 Q-input Thus, the input mux has been disabled. * The CIC/HB decimator has been replaced by an integrate and dump at the decimation rate. * To assist with meeting timing, the external RAM has been disabled. The basic application is to coherently sample two real IF streams and downconvert to baseband, while minimizing the impulse response duration of the resampling filters. git-svn-id: http://gnuradio.org/svn/gnuradio/trunk@11519 221aa14e-8319-0410-a670-987f0aec2ac5

2008-10-15Added firmware support for adc_mux to handle swapping I/Q, etc.eb
Modified dsp_core_rx.v to swap A and B mapping so that the software thinks that the TVRX is connected to A/D A. ISE 10.1 SP3 is required to compile the FPGA successfully. SP2 is insufficient. It compiles with SP2, but the firmware doesn't load. Only the F led is one in that case. git-svn-id: http://gnuradio.org/svn/gnuradio/trunk@9795 221aa14e-8319-0410-a670-987f0aec2ac5
2008-09-08Merged r9433:9527 from features/gr-usrp2 into trunk. Adds usrp2 and ↵jcorgan
gr-usrp2 top-level components. Trunk passes distcheck with mb-gcc installed, but currently not without them. The key issue is that when mb-gcc is not installed, the build system skips over the usrp2/firmware directory, and the firmware include files don't get put into the dist tarball. But we can't do the usual DIST_SUBDIRS method as the firmware is a subpackage. git-svn-id: http://gnuradio.org/svn/gnuradio/trunk@9528 221aa14e-8319-0410-a670-987f0aec2ac5
