180 2006-05-21 Martin Dudok van Heel <nldudok1 at olifantasia.com>
182 Added generic test class gr_test.
183 gr_test is a gnuradio block meant to be used in a flow_graph.
184 It doesn't do much processing, but you can specify from python every parameter you need to for testing.
185 For example history, output_multiple, input and output signature, decimation and such.
186 Especially handy for testing setting up the buffers.
187 It also touches every available input and output to check for segfaults.
188 You can also instruct it to not consume all ninput_items or not produce all noutput_items.
190 There is also a new script test_buffers.py in src/tests which uses gr_test to test setting up the buffers.
191 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.
192 (On linux: Trying to setup a buffer >shmmax
193 Note that you can set the smmax limit manually on a linux 2.6 system in the following way in a root console)
194 #set shmmax limit manually to 300MB
195 echo 300000000 >/proc/sys/kernel/shmmax
197 * src/lib/general/Makefile.am: added gr_test

205 2006-05-21 Martin Dudok van Heel <nldudok1 at olifantasia.com>
207 Solved the following bugs which result from incorrect buffersize setup:
208 sched: <gr_block gr_test (21)> is requesting more input data
210 ninput_items_required = 8192
211 max_possible_items_available = 8191
212 If this is a filter, consider reducing the number of taps.
214 python: src/lib/runtime/gr_buffer.h:108: unsigned int gr_buffer::index_sub(unsigned int, unsigned int):
215 Assertion `(unsigned) s < d_bufsize' failed.
218 * src/python/gnuradio/gr/flow_graph.py: resolved above bugs by adding + mdown.history() to nitems when appropriate
220 2006-04-24 Eric Blossom <eb@comsec.com>
222 * src/lib/general/gr_chunks_to_symbols_XX.{h,cc,i}.t,
223 src/lib/general/gr_packed_to_unpacked_XX.{h,cc,i}.t,
224 src/lib/general/gr_unpacked_to_packed_XX.{h,cc,i}.t:

226 submitted by Achilleas Anastasopoulos <anastas@umich.edu>, touched
229 2006-04-24 Martin Dudok van Heel <nldudok1 at olifantasia.com>
231 * src/python/gnuradio/gr/flow_graph.py (buffer_sizes.allocate):
232 increase buffer size allocation for blocks with a large
233 output_multiple, not just those that are decimators.
235 2006-04-05 Eric Blossom <eb@comsec.com>
237 * src/lib/general/gr_pll_carriertracking_cc.i: added
238 squelch_enable and set_lock_threshold methods.
240 * src/lib/general/gr_clock_recovery_mm_cc.h: removed erroneous
241 class prefix to method. GCC 4.1.0 complains ;)
243 2006-04-03 Eric Blossom <eb@comsec.com>
245 * src/lib/general/gr_pll_carriertracking_cc.cc (phase_detector):
248 * src/python/gnuradio/gr/prefs.py: don't load prefs if
249 GR_DONT_LOAD_PREFS environment variable is set. run_tests sets
250 this to avoid interactions with system and user prefs during
253 * src/python/gnuradio/gr/qa_rational_resampler.py: disabled two
254 tests that were causing hangs on SuSE 10.0. Should be investigated.
256 2006-03-30 Eric Blossom <eb@comsec.com>
258 * src/lib/filter/gr_fft_filter_ccc.{h,cc},
259 src/lib/filter/gr_fft_filter_fff.{h,cc}: reworked to allow

262 2006-03-29 Eric Blossom <eb@comsec.com>
264 * src/lib/general/gr_prefix.{h,cc,i}: new function that returns
265 installation prefix directory (--prefix argument to configure).
267 * src/lib/general/gr_prefs.{h,cc,i}: reworked implementation to
268 use python ConfigParser.
269 * src/python/gnuradio/gr/prefs.py: moved from
270 src/python/gnuradio/prefs.py to solve initialization problem.
272 * src/lib/general/gr_stream_to_vector.{h,cc,i}: renamed from gr_serial_to_parallel
273 * src/lib/general/gr_vector_to_stream.{h,cc,i}: renamed from gr_parallel_to_serial
274 * src/lib/python/gnuradio/gr/__init__.py: new aliases for

356 "v" to work around issue in SWIG 1.3.{28,29} and/or g++ 4.0.2.
358 * src/lib/general/gr_prefs.{h,cc,i}, src/python/gnuradio/prefs.py:
359 new class for user preferences. This uses SWIG directors (serious
360 magic), to have the actual implementation be in python, but
361 callable transparently from C++. We'll use this for user prefs
362 such as audio module, audio module options, etc.

433 * src/lib/filter/filter.i: changed. Added gr_single_pole_iir_filter_cc
434 * src/lib/filter/gr_single_pole_iir.h: changed template to have
435 partial specialization for <gr_complex,i_type,double>. Needed
436 because calculations and temporary variables have to be

930 src/lib/filter/cpuid_x86.S: filename debug info fix,
931 removed useless emms instruction in pure SSE.
932 * src/lib/filter/qa_gr_fir_ccc.cc: comment fix
934 2005-08-28 Eric Blossom <eb@comsec.com>
936 * src/lib/general/malloc16.c: fixed 64-bit pointer to int cast problem.
938 2005-08-26 Eric Blossom <eb@comsec.com>
940 * src/python/gnuradio/gr/qa_rational_resampler.py
941 (test_rational_resampler.test_002_interp): reduced random test
942 from 10k cases to 1000 cases. The 10k case turns up a single
943 failure. FIXME figure out why!
945 * src/python/gnuradio/gr/qa_fsk_stuff.py
946 (test_bytes_to_syms.test_simple_framer): fixed test case to
947 reflect 0x55 trailing tail.
949 * src/lib/filter/qa_gr_fir_ccc.cc (test_random_io): Ensure 16-byte
950 input alignment to meet contract with SIMD ccc kernel.
952 2005-08-25 Eric Blossom <eb@comsec.com>
954 * src/lib/general/gr_simple_correlator.cc: average the samples in
955 the sync field and use this to set the slicing level for the
956 payload. This helps account for frequency offsets between the Tx
959 2005-08-24 Eric Blossom <eb@comsec.com>
961 * src/lib/general/gr_simple_framer_sync.h: include GRSF_TAIL_PAD
964 * src/lib/runtime/gr_single_threaded_scheduler.cc (main_loop): now
965 only invoke sources if we are not making progress. This avoids
966 blocking (in most cases) unless we've got nothing better to do.
968 * src/lib/filter/gr_freq_xlating_fir_filter_XXX.cc.t
969 (build_composite_fir): reversed taps to fix problem introduced
970 when we "rationalized" the tap ordering a while ago. [We are
971 missing a unit test for this...]
973 2005-08-22 Matt Ettus <matt@ettus.com>
975 * src/python/gnuradio/blksimpl/gmsk.py:
976 made several changes to the filters on both TX and RX.
977 The demod filter (integrate_taps) should not average
978 over multiple samples. In reality, a few samples should
979 work, so I'm not sure why it doesn't here.
981 2005-08-22 Eric Blossom <eb@comsec.com>
983 * src/lib/general/gr_simple_correlator.cc (general_work): removed
984 incorrect magic number and replaced with constant expression.
985 [Almost as embarrassing as a buffer overflow]
987 2005-08-21 Eric Blossom <eb@comsec.com>
989 * src/lib/general/gr_simple_framer_sync.h: added one byte tail
990 padding to ensure that correlator has a chance to get synced in
991 case it was later on the previous packet.
993 * src/lib/general/gr_simple_correlator.cc (general_work):
994 corrected to use count_bits64.
996 2005-08-19 Eric Blossom <eb@comsec.com>
998 * doc/Makefile.am: clean-local now uses $(RM) -fr
1000 2005-08-18 Eric Blossom <eb@comsec.com>

1016 * src/lib/runtime/gr_single_threaded_scheduler.i,
1017 src/lib/runtime/gr_block_detail.i, src/lib/runtime/gr_buffer.i:
1018 fixes for SWIG 1.3.25. Thanks to Job de Haas for a big clue!
1020 2005-08-08 Martin Dudok van Heel <nldudok1 at olifantasia.com>
1022 Addded a new block to convert from float to unsigned char. Needed for new tv-reception example.
1024 * src/lib/general/gr_float_to_uchar.{cc,h,i}: new
1025 * src/lib/general/gri_float_to_uchar.{cc,h}: new
1026 * 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
1027 forgotten in previous patch to add gr_float_to_char)
1028 * src/lib/general/general.i: changed. Added gr_float_to_uchar and gri_float_to_uchar.
1030 2005-07-28 Eric Blossom <eb@comsec.com>

1096 progress. Not yet ready for prime time.
1098 * src/lib/runtime/gr_single_threaded_scheduler.cc: fixed spinning when
1099 sink's upstream was done, but there was a non-zero but too small
1100 amount of data left in the sink's input buffer.
1102 2005-07-18 Stephane Fillod <f8cfe@free.fr>

1190 2005-06-11 Eric Blossom <eb@comsec.com>
1192 * src/lib/general/gr_nlog10_ff.{h,cc,i}: added addition constructor arg,
1193 k, that is added to the return value. Handy for normalizing FFTs.

1200 src/python/gnuradio/gr/basic_flow_graph.py (downstream_verticies_port):
1201 modified to take into account downstream block decimation ratio.
1202 This allows us to compute big FFTs, FIRs with lots of taps, etc.
1204 2005-05-18 Eric Blossom <eb@comsec.com>
1206 * src/lib/runtime/gr_block.{h,cc,i}: new start/stop methods. These are
1207 useful for minimizing latency due to startup overhead.

1307 src/python/gnuradio/gru/__init__.py,
1308 src/python/gnuradio/gruimpl/__init__.py: refactored organization
1309 so that hierarchical blocks are physically contained in the
1310 blkimpl directory, but that for convenience in naming, all blocks
1311 appear in the gnuradio.blks package. Same story for gruimpl vs gru.
1313 Rearranged a bunch of stuff under src/python. CVS sucks!
1315 2005-02-28 Eric Blossom <eb@comsec.com>
1317 * src/lib/general/gr_frequency_modulator_fc.cc (work): fixed
1318 floating point loss of precision.
