20 * src/python/gnuradio/blksimpl/gmsk.py: Removed long deprecated
21 code. We'll give this a week or so for the dust to settle, then
22 we'll rename gmsk2.py to gmsk.py
24 2006-06-29 Tom Rondeau <trondeau@vt.edu>
26 * src/lib/general/gr_correlate_access_code_bb.cc (work):

33 Changes to access code correlator to handle BPSK phase reversal
34 killed qa_correlate_access_code. Modified the access code search in
35 test_001 to all the test to pass properly.
37 2006-06-28 Tom Rondeau <trondeau@vt.edu>

162 * src/lib/general/gr_constellation_decoder_cb.{h,cc,i}: new.
163 Maps i/q value to closest constellation point and return value
164 associated with the point. This probably obsoletes
167 * src/lib/general/gr_qpsk_slicer_cb.{h,cc,i}: new.
168 * src/lib/general/gr_unpack_k_bits_bb.{h,cc,i}: unpack bytes

183 * src/lib/general/gr_firdes.cc (root_raised_cosine): force ntaps
186 2006-05-21 Martin Dudok van Heel <nldudok1 at olifantasia.com>
188 Added generic test class gr_test.
189 gr_test is a gnuradio block meant to be used in a flow_graph.
190 It doesn't do much processing, but you can specify from python every parameter you need to for testing.
191 For example history, output_multiple, input and output signature, decimation and such.
192 Especially handy for testing setting up the buffers.
193 It also touches every available input and output to check for segfaults.
194 You can also instruct it to not consume all ninput_items or not produce all noutput_items.
196 There is also a new script test_buffers.py in src/tests which uses gr_test to test setting up the buffers.
197 It is NOT automatically run by make check yet, because it will fail with an assert when it reaches circbuf memory limit of the system.
198 (On linux: Trying to setup a buffer >shmmax
199 Note that you can set the smmax limit manually on a linux 2.6 system in the following way in a root console)
200 #set shmmax limit manually to 300MB
201 echo 300000000 >/proc/sys/kernel/shmmax
203 * src/lib/general/Makefile.am: added gr_test

206 * src/lib/general/gr_test.h: new
207 * src/lib/general/gr_test.i: new
208 * src/lib/general/gr_test_types.h: new
209 * src/tests/test_buffers.py: new script to test setting up the buffers using gr_test
211 2006-05-21 Martin Dudok van Heel <nldudok1 at olifantasia.com>
213 Solved the following bugs which result from incorrect buffersize setup:
214 sched: <gr_block gr_test (21)> is requesting more input data
216 ninput_items_required = 8192
217 max_possible_items_available = 8191
218 If this is a filter, consider reducing the number of taps.
220 python: src/lib/runtime/gr_buffer.h:108: unsigned int gr_buffer::index_sub(unsigned int, unsigned int):
221 Assertion `(unsigned) s < d_bufsize' failed.
224 * src/python/gnuradio/gr/flow_graph.py: resolved above bugs by adding + mdown.history() to nitems when appropriate
226 2006-04-24 Eric Blossom <eb@comsec.com>
228 * src/lib/general/gr_chunks_to_symbols_XX.{h,cc,i}.t,
229 src/lib/general/gr_packed_to_unpacked_XX.{h,cc,i}.t,
230 src/lib/general/gr_unpacked_to_packed_XX.{h,cc,i}.t:
231 new pseudo-templates for generating family of blocks. Patch
232 submitted by Achilleas Anastasopoulos <anastas@umich.edu>, touched
235 2006-04-24 Martin Dudok van Heel <nldudok1 at olifantasia.com>
237 * src/python/gnuradio/gr/flow_graph.py (buffer_sizes.allocate):
238 increase buffer size allocation for blocks with a large
239 output_multiple, not just those that are decimators.
241 2006-04-05 Eric Blossom <eb@comsec.com>
243 * src/lib/general/gr_pll_carriertracking_cc.i: added
244 squelch_enable and set_lock_threshold methods.
246 * src/lib/general/gr_clock_recovery_mm_cc.h: removed erroneous
247 class prefix to method. GCC 4.1.0 complains ;)
249 2006-04-03 Eric Blossom <eb@comsec.com>
251 * src/lib/general/gr_pll_carriertracking_cc.cc (phase_detector):
254 * src/python/gnuradio/gr/prefs.py: don't load prefs if
255 GR_DONT_LOAD_PREFS environment variable is set. run_tests sets
256 this to avoid interactions with system and user prefs during
259 * src/python/gnuradio/gr/qa_rational_resampler.py: disabled two
260 tests that were causing hangs on SuSE 10.0. Should be investigated.
262 2006-03-30 Eric Blossom <eb@comsec.com>
264 * src/lib/filter/gr_fft_filter_ccc.{h,cc},
265 src/lib/filter/gr_fft_filter_fff.{h,cc}: reworked to allow
266 safer setting of new taps after instantiation.
268 2006-03-29 Eric Blossom <eb@comsec.com>
270 * src/lib/general/gr_prefix.{h,cc,i}: new function that returns
271 installation prefix directory (--prefix argument to configure).
273 * src/lib/general/gr_prefs.{h,cc,i}: reworked implementation to
274 use python ConfigParser.
275 * src/python/gnuradio/gr/prefs.py: moved from
276 src/python/gnuradio/prefs.py to solve initialization problem.
278 * src/lib/general/gr_stream_to_vector.{h,cc,i}: renamed from gr_serial_to_parallel
279 * src/lib/general/gr_vector_to_stream.{h,cc,i}: renamed from gr_parallel_to_serial
280 * src/lib/python/gnuradio/gr/__init__.py: new aliases for
281 backwards compatibility with rename.

361 * src/lib/general/gr_prefs.{h,cc,i}: renamed parameter from "val" to
362 "v" to work around issue in SWIG 1.3.{28,29} and/or g++ 4.0.2.
364 * src/lib/general/gr_prefs.{h,cc,i}, src/python/gnuradio/prefs.py:
365 new class for user preferences. This uses SWIG directors (serious
366 magic), to have the actual implementation be in python, but
367 callable transparently from C++. We'll use this for user prefs
368 such as audio module, audio module options, etc.
370 2006-03-25 Eric Blossom <eb@comsec.com>

385 src/lib/omnithread/ot_posix.h, src/lib/omnithread/posix.cc,
386 src/lib/omnithread/nt.cc: mods to
387 allow specifying a max count on semaphores. This allows the
388 construction of binary semaphores by passing max_count=1 to the ctor.
389 The default behavior is unchanged.

434 Changed gr_single_pole_iir.h to make this work
435 Bugfix, to make make_check work again.
437 * src/lib/filter/Makefile.am: Added gr_single_pole_iir_filter_cc
438 Added missing gr_single_pole_avg.h and gr_single_pole_rec.h (fix make check bug)
439 * src/lib/filter/filter.i: changed. Added gr_single_pole_iir_filter_cc
440 * src/lib/filter/gr_single_pole_iir.h: changed template to have
441 partial specialization for <gr_complex,i_type,double>. Needed

909 * config/gr_set_md_cpu.m4, src/lib/filter/Makefile.am: add simd
910 support for x86_64 platform.
912 * src/lib/filter/ccomplex_dotprod_3dnow64.S,

936 src/lib/filter/cpuid_x86.S: filename debug info fix,
937 removed useless emms instruction in pure SSE.
938 * src/lib/filter/qa_gr_fir_ccc.cc: comment fix
940 2005-08-28 Eric Blossom <eb@comsec.com>
942 * src/lib/general/malloc16.c: fixed 64-bit pointer to int cast problem.
944 2005-08-26 Eric Blossom <eb@comsec.com>
946 * src/python/gnuradio/gr/qa_rational_resampler.py
947 (test_rational_resampler.test_002_interp): reduced random test
948 from 10k cases to 1000 cases. The 10k case turns up a single
949 failure. FIXME figure out why!
951 * src/python/gnuradio/gr/qa_fsk_stuff.py
952 (test_bytes_to_syms.test_simple_framer): fixed test case to
953 reflect 0x55 trailing tail.
955 * src/lib/filter/qa_gr_fir_ccc.cc (test_random_io): Ensure 16-byte
956 input alignment to meet contract with SIMD ccc kernel.
958 2005-08-25 Eric Blossom <eb@comsec.com>
960 * src/lib/general/gr_simple_correlator.cc: average the samples in
961 the sync field and use this to set the slicing level for the
962 payload. This helps account for frequency offsets between the Tx
965 2005-08-24 Eric Blossom <eb@comsec.com>
967 * src/lib/general/gr_simple_framer_sync.h: include GRSF_TAIL_PAD
970 * src/lib/runtime/gr_single_threaded_scheduler.cc (main_loop): now
971 only invoke sources if we are not making progress. This avoids
972 blocking (in most cases) unless we've got nothing better to do.
974 * src/lib/filter/gr_freq_xlating_fir_filter_XXX.cc.t
975 (build_composite_fir): reversed taps to fix problem introduced
976 when we "rationalized" the tap ordering a while ago. [We are
977 missing a unit test for this...]
979 2005-08-22 Matt Ettus <matt@ettus.com>
981 * src/python/gnuradio/blksimpl/gmsk.py:
982 made several changes to the filters on both TX and RX.
983 The demod filter (integrate_taps) should not average
984 over multiple samples. In reality, a few samples should
985 work, so I'm not sure why it doesn't here.
987 2005-08-22 Eric Blossom <eb@comsec.com>
989 * src/lib/general/gr_simple_correlator.cc (general_work): removed
990 incorrect magic number and replaced with constant expression.
991 [Almost as embarrassing as a buffer overflow]
993 2005-08-21 Eric Blossom <eb@comsec.com>
995 * src/lib/general/gr_simple_framer_sync.h: added one byte tail
996 padding to ensure that correlator has a chance to get synced in
997 case it was later on the previous packet.
999 * src/lib/general/gr_simple_correlator.cc (general_work):
1000 corrected to use count_bits64.
1002 2005-08-19 Eric Blossom <eb@comsec.com>
1004 * doc/Makefile.am: clean-local now uses $(RM) -fr
1006 2005-08-18 Eric Blossom <eb@comsec.com>
1008 * src/lib/general/gr_count_bits.{h,cc}: new gr_count_bits64.
1010 * src/lib/general/gr_simple_correlator.{h,cc},
1011 src/lib/general/gr_simple_framer.{h,cc},
1012 src/lib/general/gr_simple_framer_sync.h,
1013 src/python/gnuradio/gr/qa_fsk_stuff.py: changed length of SYNC
1014 code from 32 to 64 bits.
1016 2005-08-16 Andrew Thomas Beck <Andrew.Beck@postgrads.unisa.edu.au>
1018 * src/lib/runtime/gr_vmcircbuf_createfilemapping.cc (gr_vmcircbuf_createfilemapping): fixes.
1020 2005-08-15 Eric Blossom <eb@comsec.com>
1022 * src/lib/runtime/gr_single_threaded_scheduler.i,
1023 src/lib/runtime/gr_block_detail.i, src/lib/runtime/gr_buffer.i:
1024 fixes for SWIG 1.3.25. Thanks to Job de Haas for a big clue!
1026 2005-08-08 Martin Dudok van Heel <nldudok1 at olifantasia.com>
1028 Addded a new block to convert from float to unsigned char. Needed for new tv-reception example.
1030 * src/lib/general/gr_float_to_uchar.{cc,h,i}: new
1031 * src/lib/general/gri_float_to_uchar.{cc,h}: new
1032 * src/lib/general/Makefile.am: changed. Added gr_float_to_uchar and gri_float_to_uchar. (Also added gr_float_to_char.h which was
1033 forgotten in previous patch to add gr_float_to_char)
1034 * src/lib/general/general.i: changed. Added gr_float_to_uchar and gri_float_to_uchar.
1036 2005-07-28 Eric Blossom <eb@comsec.com>
1038 * src/lib/general/qa_gr_circular_file.cc (t1): conditionalized
1041 2005-07-24 Stephane Fillod <f8cfe@free.fr>
1043 * src/lib/runtime/gr_vmcircbuf_mmap_tmpfile.cc: get correct

1090 number to frequency mapping. Fixed a couple of problems related
1091 to reversing filter tap order.
1093 2005-07-20 Martin Dvh <gnuradiomail@olifantasia.com>
1095 * src/lib/runtime/gr_vmcircbuf_createfilemapping.{h,cc}: new.

1099 2005-07-19 Eric Blossom <eb@comsec.com>
1101 * src/lib/filter/gr_fft_filter_fff.{h,cc,i}: new. Work in
1102 progress. Not yet ready for prime time.
1104 * src/lib/runtime/gr_single_threaded_scheduler.cc: fixed spinning when
1105 sink's upstream was done, but there was a non-zero but too small
1106 amount of data left in the sink's input buffer.
1108 2005-07-18 Stephane Fillod <f8cfe@free.fr>
1110 * config/gr_libgnuradio_core_extra_ldflags.m4,

1138 returns the right order. We now require the "right" order for
1139 taps, instead of the reversed order ("dot product order") we used to
1142 2005-07-13 Martin Dvh <gnuradiomail@olifantasia.com>
1144 * config/gr_check_createfilemapping.m4,

1198 * src/lib/general/gr_nlog10_ff.{h,cc,i}: added addition constructor arg,
1199 k, that is added to the return value. Handy for normalizing FFTs.
1201 * src/lib/filter/gr_fft_filter_ccc.{h,cc,i}: new. FFT based FIR filtering.
1203 2005-06-10 Eric Blossom <eb@comsec.com>
1205 * src/python/gnuradio/gr/flow_graph.py (buffer_sizes.allocate),
1206 src/python/gnuradio/gr/basic_flow_graph.py (downstream_verticies_port):
1207 modified to take into account downstream block decimation ratio.
1208 This allows us to compute big FFTs, FIRs with lots of taps, etc.
1210 2005-05-18 Eric Blossom <eb@comsec.com>
1212 * src/lib/runtime/gr_block.{h,cc,i}: new start/stop methods. These are
1213 useful for minimizing latency due to startup overhead.
1214 * src/lib/runtime/gr_single_threaded_scheduler.cc: call new methods.
1216 2005-05-18 John Gilmore <gnu@toad.com>

1313 src/python/gnuradio/gru/__init__.py,
1314 src/python/gnuradio/gruimpl/__init__.py: refactored organization
1315 so that hierarchical blocks are physically contained in the
1316 blkimpl directory, but that for convenience in naming, all blocks
1317 appear in the gnuradio.blks package. Same story for gruimpl vs gru.
1319 Rearranged a bunch of stuff under src/python. CVS sucks!
1321 2005-02-28 Eric Blossom <eb@comsec.com>
1323 * src/lib/general/gr_frequency_modulator_fc.cc (work): fixed
1324 floating point loss of precision.
