* Add custom FPGA build.jcorgan2009-07-3012-3/+1704
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 * The CIC/HB decimator has been replaced by an integrate and dump at the decimation rate.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

| | | | | | FPGA build to use integrate-and-dump decimator instead of CIC/HB combination. This provides a much shorter time duration impulse response for the same decimation rate, at the expense of worse stop-band rejection. git-svn-id: http://gnuradio.org/svn/gnuradio/trunk@10888 221aa14e-8319-0410-a670-987f0aec2ac5
