<p>This project aims to provide an API for different programming languages to load firmware, start/stop and communicate with the BeagleBone PRUs (Programmable Realtime Units) from user space using the RemoteProc, RPMsg drivers. Example firmware and user space software are provided to demonstrate the use of the project.</p>

<p>While the BeagleBone family has a large number of pins available on their P8/P9 headers, projects requiring a large amount of GPIO I/O may still be infeasible due to pinmux conflicts with other interfaces (SPI, UARTs, etc.). The newer PocketBeagle platform is even more restricted in the number of available GPIOs for interfacing. In addition, bi-directional bus communication using GPIOs is infeasible, as each GPIO is configured for either input or output. This project will combine your hardware and software skills to address these limitations by creating a shift register-based hardware design that will allow serial streams of data going in/out of the PocketBeagle or BeagleBone family GPIOs to be mapped into a bi-directional communications bus</p>

This project aims to enable the development of models that are suitably efficient for use in real-time interactive applications on embedded systems such as the BeagleBone-based Bela. At the project's core is difflogic, a recent technique that employs sparsely-connected network composed of basic logic gates to obtain small models and fast inference. The core goal of the project is to enable a convenient workflow for developing difflogic models and running them on the Bela, with an expected workflow of developing and training models on a larger machine, followed by exporting the model to C and cross-compiling it for the BeagleBone - either the main CPU or the PRUs. To support this, I will develop wrappers for exporting compiled difflogic models for use in the languages supported on Bela (C++, Pure Data, SuperCollider, Csound). I will then build out integrations and applications of difflogic for the rapid development of useful audio models, exploring the possibilities for combining difflogic networks with DDSP (differentiable digital signal processing) and cheap/lightweight techniques and toolkits, "porting" well-known ML architectures to difflogic networks, and training difflogic networks to approximate the behavior of existing neural networks (knowledge distillation). I will develop example applications involving sound analysis, classification, and synthesis, and experiment with interactive machine learning. Finally, I will apply these techniques to a creative application inspired by work on bytebeat and sound matching: generating networks of logic gates to approximate sounds and exploring the space of such sound-generating networks. I will train difflogic gates to reproduce particular sounds, treating the entire network as a bytebeat-style audio-generating function of time. Lastly, I will build an interactive application to explore the space of sound-generating networks (e.g. by mutating or morphing networks) and visualize the execution of logic gate networks.

<p><strong>corobo Enhancement</strong></p> <p>The goal of this project is to make corobo secure by reducing its surface vulnerability. It also includes implementing a better testing infrastructure to test plugins like LabHub, as well as to make the existing plugins configurable so that they can also be adapted by other communities to cater their needs.</p>

<p>SPI slave driver implementation. The task is to create a driver controlling SPI hardware controller in slave mode, and to ensure optimal performance through the use of DMA and interrupt. Creating an easy to implement realization of SPI slave would definitely help the BeagleBone community members to write applications based on SPI much more easily. The first implementation of my protocol driver is going to example of a bidirectional data exchange. This application will provide the BeagleBone community with valuable experience and will be a good example of SPI slave. Hardware limitations make it impossible to perform any realization of the device using SPI slave. Sending away data to the master during one transaction is not possible. One transaction is enough to receive data by slave device. To receive and send back data, two transactions are needed. The data received from master device in a single transaction is transferred to the user after completing the transaction. The user's reply to received data is sent in the next transaction.</p>

<p>To develop an analyzing routine at least for python and java that will find all documentation strings in a file, parse them into specific groups and check them against a specified documentation style given by the user. The functionality can be extended so that the analyzing routine provides a patch that re-formats the documentation correctly, checks for grammatical errors (eg: checking parameter’s description for imperative present tense) and perform other aesthetical fixes (i.e capitalization, sentence termination with a period).</p>

<p>The aim of this project is to implement the architecture that enables the support for nested - languages by default. The users of coala would not have to concentrate on writing new bears/ analysis routines. This project would perfectly work with the existing bears.</p> <p>On the successful completion of project, coala would have the support for the following programming languages:</p> <ol> <li>Codeblocks in RST</li> <li>PHP and HTML</li> </ol> <p>It is important to note that the aim of the project is not to provide a full fledged support for all nested languages , but to lay the foundation of architecture. It’s not possible to provide the full fledged support for languages until coala has a new feature where the bears can accept AST’s and lint through them, instead of taking files as input.</p>

<h4>GitMate for all!</h4> <p>This time with user configurable plugins!</p> <h3>About the product</h3> <p><strong>GitHub</strong>, <strong>GitLab</strong> and <strong>BitBucket</strong> support webhooks for common events like opening/closing/commenting on Merge Requests, creating Issues, etc. These webhooks could be configured for automated response using their own API's for comments, tests/integrations, etc. <strong>GitMate</strong> merely acts as a tunnel for these events and responds accordingly. The interface for these API's is held by its wrapper library, IGitt.</p> <h3>Aim of the project</h3> <p>This project is aimed at extending the support for <strong>GitMate</strong> to <strong>GitLab</strong> and <strong>BitBucket</strong> repositories. This adds up to unified and automated code analysis and maintenance on the big three code hosting platforms.</p> <h3>Implementation</h3> <p>This project consists of implementing <strong>GitLab</strong> and <strong>BitBucket</strong> interfaces in <strong>IGitt</strong>, following the already implemented <strong>GitHub</strong>'s convention, while simultaneously creating webhook responders and tasks for the same on <strong>gitmate-2</strong>.</p> <p>Extending plugins is quite easy on <strong>gitmate-2</strong> following <code>gitmate_testplugin</code> as an example, thanks to its plugin-based architecture.</p>

<p>This project is about adding a verification process for the pull requests made to coala. There are many special types of commit messages that should only be used in conjunction with patches containing a special type of content. Such commits should be detected, and allowed or disallowed based on configuration settings in .coafile.</p>

<p>The main purpose of this project is to make the text-editors of coala more robust and active. This will be done through ensuring that the plugins are up-to-date with proper tests and continuous integration, to make maintenance more simplified for contributors in the future. This project will be completed through the use of several open-source tools. Further, the completion of this project will lead to other developers having the freedom to use coala in their favourite text editors. The ease of usage in different text editors may also help potentially serve as a way to popularize coala.</p>

<p>Result reporter tool to convert linter/bear results into multiple formats.</p>

In this GSoC project, I worked on developing a multimedia processing system, focusing on commercial detection and replacement using deep learning. I have developed a real-time, efficient solution that enhances media consumption experiences by seamlessly integrating custom audio streams during commercial breaks.

<p>As coala tries to be welcoming organization for newcomers, giving them clear pathways and as much direct assistance as possible. However, it is already known that newcomers face many barriers while attempting to contribute to the open source community for the first time. Some barriers they face include orientation issues that can potentially demotivate newcomers from placing their first contribution. On the other hand, gamification is widely used to engage and motivate people to accomplish task and improve their performance.Therefore, the goal of this project is to use gamification to orient and motivate newcomers to overcome onboarding barriers to contribute and engage with coala and its community.</p>

<p>The aim of the project is to ease the process of testing bears in coala by significantly improving the testing API to yield favorable, easy to understand results, add support for at least 8 additional useful linter bears, integrate the MarkdownBear with useful plugins, include <code>remark-lint</code> to report error messages and get the MarkdownBear to a bug free state, and enhance documentation to include the newly written Linter bears.</p>

<p>The goal of project meta-review is to track emoji responses to review comments. These responses would be collected, processed and displayed. This project builds a meta-review system on the community site and gh-board to display score ranking statistics and meta-reviews in need, respectively, and encourage people to do meta-review.</p>

<p>The <a href="http://www.creative-technologies.de/linux-based-low-latency-multichannel-audio-system-2/" target="_blank">CTAG face2|4 Audio Card</a> is a multichannel I2S soundcard based on the <a href="http://www.analog.com/media/en/technical-documentation/data-sheets/AD1938.pdf" target="_blank">AD1938 audio codec</a> by Analog Devices. Currently the soundcard can only be used with a <a href="http://beagleboard.org/black" target="_blank">BeagleBone Green/Black</a>. Due to CPU intensive calculations in digital audio the <a href="http://beagleboard.org/x15" target="_blank">BeagleBoard-X15</a> seems to be a perfect alternative to realize more complex audio effects and synthesizers and achieve lower latencies. Moreover the BeagleBone-X15 (<a href="http://www.ti.com/lit/ug/spruhz6e/spruhz6e.pdf" target="_blank">TI AM5728 SoC</a>) offers two separate DSPs (<a href="https://www.ti.com/lsds/ti/processors/dsp/c6000_dsp/c66x/overview.page" target="_blank">C66x</a>) which can be used to offload cpu-intensive multimedia tasks in asymmetric multiproccesing (AMP) configurations. The goal of the project is to port the soundcard drivers to the BeagleBoard-X15 and create an user-space library to make use of C66x DSPs via TI OpenCL and TI DSPLIB.</p>

<p>Gitmate, a git workflow management bot created by coala, hasn't been actively maintained in the last 3 years. My project aims to update it and bring it back to active use for the coala community. I plan to undertake various improvements to Gitmate as well as IGitt, the underlying library that powers Gitmate's git operations.</p> <p>My primary goal is to set up Gitmate for the coala community. I will also upgrade both Gitmate and IGitt to the latest API versions of Github, Gitlab and Jira and add support for the latest python versions by upgrading the dependencies. Along with this, I will update various aspects of the documentation of both these projects, improve testing, and ensure that the Continuous Integration setup is in perfect condition. The last phase of my project will involve merging three pull request plugins into a combined plugin and improving various pull request events. Throughout the project, I will work on feedback from the coala community and try my utmost best to improve their experience with using Gitmate.</p>

Deep learning is a subset of machine learning that involves the use of neural networks with multiple layers. Neural networks consist of multiple layers of interconnected nodes, each building upon the previous layer to refine and optimize the prediction. The main goal of the project is to accelerate as many types of layers as possible using OpenGLES and Darknet as deep learning frameworks. Accelerating the performance of deep learning models is crucial for real-time applications. GPUs are widely used to accelerate the computations in deep learning models, as they can perform many operations in parallel.OpenGLES is a widely used graphics API that provides a framework for performing computations on GPUs. By using OpenGLES to perform computations, we can leverage the parallel processing power of the GPU to accelerate the performance of deep learning models.

<p>Bitbanging an SPI or/an I2C device in Linux leads to a lot of problems.It consumes a lot of valuable CPU cycles.And since Linux is an non-preemptive OS(And not an RTOS),once we start bitbanging,other important tasks that require CPU time would suffer.Thus,there are a lot of software overheads in doing the same. To avoid this on the BBB,we could offload the task of bitbanging I2C,SPI,UART, to the PRU.The PRU is a separate core and,hence,not affected by the Linux Scheduler. Hence the motivation for exposing the PRU as an I2C,SPI,UART device comes from the fact that they would be no software overheads in doing it and hence,we would gain extra serial interfaces without wasting valuable CPU cycles in bitabanging.</p> <p>This project involves writing Device Tree Overlays,Device Drivers and PRU firmware code for Bitbanging I2C,SPI and UART.</p>

<p>The idea behind the project is to make Xen hypervisor available and easy to use on beagleboard-x15. This implementation will allow users to experiment on embedded virtualization and in related fields like automotive, critical systems prototyping and processor's resources sharing. It might also provide very interesting possibilities for heterogeneous resources' utilization. The most interesting outcome is the availability of open-source virtualization on top of the open-source hardware.</p>

<p>coala is a modular and language-agnostic tool for performing static code analysis. The aim of coala is to make static code analysis easier for the users. However, getting started with coala for a user requires prior knowledge about different bears coala has (users may get confused among lots of available options), how to create a correct coafile, what values to provide for settings, avoid duplicity among the bears, what bear-dependencies to install, etc.</p> <p>coala-quickstart is a tool with an aim to help users to quickly get started with coala by doing all the boilerplate work. It generates a .coafile (coala's configuration file) that is tailored to the project.</p> <p>The ultimate goal of the project is to make coala-quickstart generate a more tailored coala configuration file with less user effort and time.</p> <p>The primary objectives of the project are:</p> <ol> <li>Develop a mechanism to extract information of interest to coala like setting values from some common kinds of project files like <code>Gruntfile.js</code>, <code>Gulpfile.js</code>, etc.</li> <li>Make coala-quickstart include relevant bears to the project in the generated coafile.</li> <li>Improving the user interface, increasing automation and adding some minor features.</li> </ol>
