6e94d9ce51 #108 [WIP] Created new ThreadPool class with a static ScheduledThreadExecutor that is now shared by all components. Removed ThreadPoolManager from all classes. Consolidating into 1 pool seems to have reduced CPU usage by ~15-20%. Overall memory usage is also reduced. 2017-01-22 09:33:47 -05:00

078a6fddce Closes #71 - frequency controller throws exception when exceeding min/max tuning limits of a tuner.
Updated code to show dialog to user whenever the tuning limit has been exceeded.  Added new InvalidFrequencyException that includes the requested invalid frequency and the valid frequency limit that was exceeded

c3d52ff86e Merges #34 Major redesign of Tuner, Channel and Alias management.
Changes to model, view and controller components and updates all gui
editors.  Removes the configuration panel and tree and replaces with 3
new panels.  Updates playlist.xml to a new playlist_v2.xml format.

218eeb1848 WIP #34 - more work on tuner model and view. Includes new tuner
configuration and tuner configuration assignment editors.  Beginning of
tuner editor panel rework.   Removes most of the remaining JTree
configuration pieces.  Updates the settings manager to load and save
tuners and refactors all of the tuner configuration management out into
the tuner configuration model.

63cea60c42 Merges master CF2C0CA, EEAD22F, 5F2D8C8, 22D3871, and 6F2A7E8 - updates
libusb transfer processing and shutdown/cancel management of transfers
in progress.

cf2c0ca07d Resolves significant memory usage issue - updates Airspy and HackRF with
the recent changes applied to RTL2832 Tuner controller for processing of
libusb transfer buffers.

0951277915 Tuner Controller update to better handle automatic center frequency
calculation when additional channels are allocated.

Incorporates tuner specific definition of overall usable bandwidth, so
that tuners like airspy can specify 90% of 10 MHz (ie 9 MHz) is truly
usable and the fringe 10% is unusable rolloff.

Also includes tuner-specific defining of the width of the central spike,
or a value of 0 indicates that the entire range is usable (ie airspy).

f04a6727b0 Resolved issue with channel label display in spectrum overlay panel
when a new tuner is added.

Cleanup of debugging messages.

70e62ebb35 Adds airspy USB tuner support and updates the spectral display
component.

-Airspy supported with 10 and 2.5 MSps sample rates.  Additional
decimation may be added later.

-Spectral display updated to include smoothing and filtering options.

Note: the decimated output of a tuner channel from the airspy is
48,076.9 samples per second, versus the normal 48 kHz decimated rate.
This is 1.0015 times the normal rate and doesn't appear to impact the
decoders or audio processing.  Therefore, no fractional resampling has
been added.

f4d8ea281d Initial commit of redesigned internal processing and audio management.
Note: Several of the decoders are currently non-functioning in this
commit.  If you want the latest functioning codebase, please checkout
the commit prior to this one.  All decoders will eventually be updated
with this new architecture.

Currently broken:
- Logging and recording
- Aux decoders (Fleetsync/MDC/LoJack/Tait)
- LTR/Passport decoders

Changes in this commit:
- Module architecture for decoders and components with central
provisioning by the DecoderFactory
- Transition from Complex sample stream processing to float buffer
processing for improved memory management
- Redesigned filter structures - to support buffers and streams
- Resolved several memory leak issues
- Universal sharing of the thread pool manager
- Added centralized audio management with call/user prioritization and
new gui with mute/volume controls
- Embedded audio metadata for eventual streaming support
- Redesigned ProcessingChain to support independent re-use
- Added new TrafficChannelManager to handle traffic channel allocations
- Traffic Channel pool size and Call timeout available in P25 and
MPT1327 configs
- Redesigned channel and decoder gui components

ba053457bd Out of memory fixes and updates to the P25 decoder.
Memory Fixes
Decreased the decimation process repeat timing so that it runs smaller work chunks more often
Decreased scheduled thread pool to 2 hot threads
Wrapped all scheduled thread pool runnables in try/catch blocks so that an exception doesn't kill the sample buffer processing thread and cause the buffer to grow unbounded.

P25 updates
Moved TSBK crc checks into the message framer so that message corrections don't occur after the message is constructed.
Added more functionality to the channel state for handling registrations and call events.

ae0568ff3b Updated spectral display to used dBm scale and removed baseline/amplification items.
Updated sample handling code to use -1.0 to 1.0 float values throughout, to support P25 decoder and symbol filter.

e61c3a891c Memory/CPU performance improvement and Audio/Mixer source restructuring
Converted to use float primitives and to keep samples in buffer format until the sample rate is decimated to 48kHz.  
Added new non-recursive, CIC decimation filter -- untested

Updated sound card/mixer input source management.  Now testing for mono/stereo support for each card and limiting channel choices accordingly.  Separated the mixersource into a ComplexMixer and and SimplexMixerSource.  The ComplexMixer is used for sound card based tuners like the funcube.  The SimplexMixerSource is used for demodulated sound card inputs.

Interfaces for sample handling - standardized on using 'Complex' to indicate I/Q samples and 'Simplex' to indicate demodulated float samples.  The processing chain now accepts either a decimated (48k) list of complex samples from a tuner channel source, or a 48k simplex buffer (array of demodulated float samples).

Resolved issue with HackRF tuner not applying tuner configuration information.

5f4e7652bd HackRF - final check-in. Changed all tuners to use the low-level API of the usb4java library to resolve limitation in high-level API that constrains maximum sample rate to ~2.0 MHz. Added console logging to logback. 2014-10-20 23:09:50 +00:00
