Denny Sheirer	0eec2e7ab8	Updates complex decimation filters to use either scalar or vector optimal implementation. (#1148) ... Updates HackRF native byte buffers with automatic DC removal. Creates new half-band channel source to replace the cic-based channel source in the heterodyne channelizer. Resolves issue in RTL native buffer processing. Creates a CACHED thread pool and reduces the number of threads for the SCHEDULED thread pool to 2. Changes each of the channel source implementations to use a dedicated thread (Dispatcher class) instead of the scheduled thread pool, to reduce the amount of buffered/retained samples objects in memory. Lots of other small changes and tweaks. Removes last of Reusable buffer code. Updates DFTProcessor to use a single thread scheduled executor. Updates Polyphase channelizer to use threads instead of an executor. Removes a number of unused classes. Commenting out window calibration. Scalar is faster in both implementations. Adds vector and scalar implementations for windows. Repackages window and window type classes. WIP adds vector implementations for Airspy non-interleaved buffer iterator and calibration plugins for both interleaved and non-interleaved buffer iterators. WIP adds vector implementations for Airspy interleaved buffer iterator. Work on developing scalar and vector implementations of airspy sample conversion and airspy native buffer processing. Introduces new INativeBuffer framework where tuner raw samples are retained in their native (compressed) format until when they're needed and they are converted on-demand into smaller complex sample buffers to aid garbage collection. Removes all usage of ReusableComplexBuffers and ReusableChannelREsultsBuffers. Updates polyphase channelizer to be more efficient in output channel processing. Updates ViterbiDecoder to change Map usage to array for memory efficiency. Updates channel processors to used scalar implementation for gain and mixer, until the polyphase channel results can be fixed to be a multiple of the SIMD lane width. Resolves final changes for the conversion from interleaved sample arrays to complexsamples buffers for distributing baseband samples to channels and processing chains. Updates tuner channel sources and all decoders to receive new complex samples buffers, removing the previous reusable complex buffers as the default baseband samples buffer object. Still to resolve is the ComplexMixer implementations. Needs validation and a calibration implementation with an update to the complex mixer factory. Updates the DMR decoder to use optimal (scalar vs vector) implementations of filter and AGC controls. Updates the AM demodulator for separated I&Q float sample processing. Code review and testing changes. updates build script for runtime configuration. Integrates calibration manager with main sdrtrunk application. Updates NBFMDecoder to use new optimized FIR and Decimation filter options. Updates real half-band decimation filters to select the optimal (scalar vs vector) implementation. Adds calibration manager plugins. Adds calibration manager and plugins to determine the optimal (scalar vs vector) implementation type to use for various classes of dsp components. Adds vector squelching FM demodulator and cleans up the IIR filter and power squelch to use all floats. Adds vector implementation of FM demodulator. This introduces a new interface that accepts i/q samples as two separate float arrays, versus an interleaved array, which enables more efficient processing. This new complex sample interface will be used across the codebase eventually. Adds ComplexOscillator and a SIMD version VectorComplexOscillator. Deprecates the LowPhaseNoiseOscillator because the ComplexOscillator is about 35% faster. The vectorized version is about 43% faster when SIMD lane width is 8x. Adds new vector complex filters and new real oscillators. Note: the RealOscillator using straight Java math sin() function is 3x slower than the existing legacy implementation. Will replace this with a complex oscillator that only uses the real part. Updates ComplexFIRFilter to be 50% more efficient. Adds 23 tap filter implementations. Will not add 63-tap implementations because they are slower than the default vector implementation. Adds 15-tap customized vector half band filters. Adds initial custom complex vector half-band decimation filters for 11-tap and 15-tap decimation filters.. Adds vector complex half band filter implementations. Note: performance of the generic 64-bit 2-lane filter is horrible and is not included. Optimizes complex half-band filter to be 27% more efficient. Implements vectorized real half-band filter implementations. Implements a new FIR filter class that processes sample buffers instead of single sample at a time. Refactored all of the calibratons to be time-duration based. Testing on windows i7 gen 3 CPU showed that it took 1000x longer for one of the calibrations to run, versus my AMD 5800x. Changed gradle jvm args so that the windows plaf export is always applied. Updates gradle build script to ensure incubator module is included and to cleanup javafx library management for building runtime images. Testing tweaks and changes. Adds logging limiter to dispatcher for buffer overflows Adds User Preferences editor for performing Vector/SIMD calibrations and new startup dialog prompting the user to perform calibrations. Updates calibration manager and all calibration implementations to add warm-up and test phases and to reduce the overall time it takes to calibrate a system.

Denny Sheirer	b67d4d92dc	Identifier Framework and Message/Event Processing Overhaul (#455) ... * WIP on new P25 message framer. * WIP on new P25 message framer. * Adds new 1/2 and 3/4 rate trellis decoders. Still trying to chase down why there is a sync pattern mismatch in the NID buffer queue. * WIP - new p25 message framer works correctly now. PDU's are dectected and decoded using the 1/2 and 3/4 rate trellis decoders. Packet Sequences are assembled. Need to add a new packet sequence message factory that can detect Motorola Auto Registration Service (ARS) formatted UDP/ID packets and SNDCP command packets. * WIP - removes nullify on channel results queue. * WIP - updates message framer for TSBK 1/2/3 processing. * WIP removing P25 sync pattern and nid bits from all message parsers. * WIP - merges identifier framework branch changes into this branch. * WIP on updating link control words to new format and identifier framework. * WIP - implements rest of link control words for extended formats * WIP - initial work on ISP/OSP TSBK message restructuring. * WIP - adds more TSBK ISP and OSP messages * WIP - finished updating most of the TSBK ISP and OSP messages. Converted all messages to no longer include the NID (nac + dataunitID) so that each message can simply hold the parsed values. Removed AliasList as an argument to each message and updated all messges to use the new IIdentifer and IAPCO25Channel interfaces. Removed legacy TDU and LDU link control messages and replaced with a single LinkControlWord class hierarchy. P25 decoder state is not yet updated for the new message structure. PDU message parsing is not fully implemented. * WIP - adds some Multi-Block trunking control messages with Alternate and Unconfirmed formats. * WIP - Fully implements AMBTC and UMBTC PDU message parsers. Some package restructuring. * WIP - Resolves Link control parsing in LDU1 and 2 messages. * WIP - finishes updating TSBK and Link Control messages. Adds support for moto link control messages for patch groups. * WIP - finishes updating TSBK and Link Control messages. Adds support for moto link control messages for patch groups. Adds support for moto ARS service, IPV4 decoding, and UDP/IP packets. * WIP - finishes SNDCP packet data with header parsing. Compressed IP or UDP headers are not yet supported, but are logged as such. * WIP - converts all talkgroup identifiers to integers and updates alias list to create a per-protocol map of talkgroup id's to alias. Inserts a legacy talkgroup (ltr, p25, passport, mpt1327, mdc, etc.) conversion utility to convert existing legacy (string) talkgroups to new integer talkgroup format. Creates an audio packet manager to insert metadata into audio packets before streaming packets for playback, recording, and/or streaming. Creates identifier collection to manage current identifiers in each of the channel and decoder states. Creates simplified channel metadata to maintain the now playing display. Moves channel attributes (alias list, system, site, name) as configuration identifiers in the channel state. Many other refactoring and updates. * WIP - numerous updates to push use of identifier collection throughout the system. Updates the channel metadata and audio packet processing logic. Implements a large portion of the P25 decode state processing. Updates traffic channel management. Adds user preferences for timestamp and identifier formatting, however doesn't add a user interface yet. * WIP - initial implementation of user preferences editor window. * WIP - updates preferences editor window to close and dispose window but retain javafx event thread running. * WIP - fully updates p25 decoder state and traffic channel processing to use the new identifier framework. Cleans up channel event processing and removes channel model as the sole broadcaster of channel events. Channel processing manager now listens for all start/stop events and requestors dispatch event directly to the channel processing manager. Resolves issue in airspy that was causing user interface to lock-up. The issue appears to occur when the dongle is plugged into a usb port that can't fully support the data rate. sdrtrunk now recognizes these errors and warns the user that they should use another usb port. * WIP - updates alias action manager and adds new talkgroup range alias identifier. Updates playlist to incorporate a version number so that the playlist updater only runs when needed, to update a playlist to the correct version format. Updates user preferences to use the google event bus to broadcast preference update notifications to remove the need for listeners to register directly on the user preferences instance. * WIP - updates alias id editors to flag invalid values and moves legacy alias ids to legacy package. Updates event logging configuration to add traffic channel decode events and decoded message logging. Removes binary message logging since that is now replaced with demodulated bitstream recording. * Removes system properties from user preferences. Preferences are stored in the OS-dependent settings store (windows - registry) * Updates MapService to use new PlottableDecodeEvent instead of monitoring all of the decoded messages. Updates Fleetsync decoder and related messages to identifier framework. * Updates LTR-Net, Fleetsync and LJ1200 decoders to new identifier framework and adds support for user preferences for formatting of LTR-Net and fleetsync talkgroup identifiers. Breaks LTR-Net messages into various message types and uses a new message factory. Removes alias list from message processing for ltr-net, fleetsync and lj1200. * Updates LTR-Standard messages to Identifier framework. * Removes Plottable and IPlottable from codebase. * wip * WIP on MPT-1327 messages. * Updates MPT1327 decoder to identifier framework and new traffic channel manager. This decoder still needs to be updated with a new message parser factory and a sync detector like what is now used for P25. * Updates MDC1200 decoder and message to identifier framework. * Updates Tait1200 and Passport decoders to identifier framework. * Merges changes from master branch. * Removes legacy alias support classes. Updates passport message processor to only pass valid messages. Adds support to playlist updater for converting passport mobile ids to become passport talkgroup values. * Updates P25 decoder state and channel state to better track allocated traffic channels. Resolves issue in timestamp manager for trackig message timestamps. Resolves issue in airspy tuner that was causing the tuner to stop sending samples to the application. * Update P25 Decoder state to process SNDCP management messages and PDU messages. Updates P25 activity summary to display network and site details. Resolves issue with overlay panel that prevented enabled channels from rendering correctly when zoomed in. * Creates a new FilePreferences as part of the user preferences to begin the transition of SystemProperties over to user preferences and consolidate file preferences in one location. Updates playlist manager to use the new file preferences and to use default.xml as the new default playlist name, following conversion of a playlist_v2.xml format to the new format. In the near future, the user will be able to edit file locations and to create/use other playlists.

Denny	60ffb18cd9	39 [WIP] cleans up the reusable buffers and creates both real and ... complex variants.	2018-03-25 09:13:03 -04:00
Denny	f2f2c92afe	[WIP] Implements reusable sample buffers across all components. This ... produces a significant reduction in memory usage, especially for tuners like the airspy and hackrf that produce 10/20 MSPS sample rates. This is observed to be around 66% reduction in peak memory usage and provides a more stable memory utilization across time reducing stress on the garbage collector. Use of these reusable memory buffers will be pushed further down into the processing chain modules to ensure we keep new object creation to the lowest levels possible.	2018-02-03 10:05:16 -05:00
