ABS 2014 - The Growth of Android in Embedded SystemsBenjamin Zores
The document discusses the growth of Android in embedded systems. It provides an overview of Android's history and architecture. While Android has brought Linux to many devices, its proprietary development model and design flaws mean it is not optimal for all embedded use cases. Specifically, it can be a burden for manufacturers due to fragmentation, proprietary drivers, and high hardware requirements. However, Android remains attractive for its application framework, time-to-market advantages, and focus on the user experience rather than low-level software.
Droidcon 2013 france - The Growth of Android in Embedded SystemsBenjamin Zores
1) Android was originally developed by Android Inc. in the 2000s and was purchased by Google in 2005. It was revamped to be based on Linux and the first Android smartphone was released in 2008.
2) Android is appealing for some embedded systems due to its standardized application framework and aggressive time-to-market. However, it also has some downsides for performance-critical systems due to its Java-based design and proprietary changes from vanilla Linux.
3) While Android has brought Linux to many consumer devices, it has also slowed down some innovation and standardization in embedded systems. Linux remains a better choice for embedded devices not focused on apps and with high performance needs.
The document discusses porting a device to run Android Jelly Bean. It begins with an introduction of the speaker and their background working with open source software. The agenda then outlines the topics to be covered, including the Android build system, various Android subsystems, and porting specific devices. Device porting involves designing the custom board around a reference design, ensuring hardware compatibility, selecting supported peripherals, writing detailed specifications, and addressing pin multiplexing. The goal is to provide developers a consistent environment.
The document provides an overview of porting Android to custom hardware devices. It discusses the key requirements for compatibility with Google services and the Android ecosystem. It then describes the process of creating a custom Android device using the AOSP and Linaro sources, including setting up the device directory, bootloader, kernel, and init system. The document shares the speaker's experience porting Android to various hardware architectures and outlines some of the differences between the Android and typical Linux systems.
This document provides an overview of porting Android to new platforms. It discusses the Android software stack, the Android Open Source Project structure, the AOSP code structure, common Android hardware abstraction layers, device configuration files, the AOSP build process, the Android boot process, and Android debugging tools.
We all want our devices to boot faster, but how much effort do you want to dedicate to optimizing and maintaining a custom kernel and apps? This presentation offers a graded list of things you can do to reduce boot time. They start with simple changes, such as adjusting the position of your main application the init sequence. Then there are the changes you can make to the kernel and bootloader configuration to speed things up, and finally, there are moderately advanced techniques such as using U-Boot in falcon mode.
All of this is done using standard configuration techniques, with the idea of being able to maintain these changes in the future. I will show the effect of each of these changes on typical a embedded dev board so that you can judge for yourself where on the journey you want to jump off.

Embedded Android: Android beyond the smartphoneChris Simmonds
We are all familiar with Android as an operating system for smarphones. Looking beyond that,
Android is an open-source operating system that runs on top of Linux, which opens up a wide range
of applications in the embedded space. Using Embedded Android, you get the well-known user
interface, with it’s familiar touch screen gestures, and you get a well-known programming interface
based on Java. So, why would you not want to consider Embedded Android?
Android is beginning to take off as an embedded operating system alongside Windows Embedded and traditional embedded Linux. What are the motivations for using Android? What are the potential problems? This presentation addresses these points, with use-cases based on real-world applications of Embedded Android
Android provides concise logging and debugging capabilities. The boot process involves initializing hardware and loading drivers in the bootloader and kernel stages. The init process then sets up the file system and executes scripts to start services like the zygote process and boot animation. There are several Android logs including main, events, radio, and system. Tools like dumpsys and dumpstate provide detailed system status information. Native crashes produce a log with the build fingerprint, registers, stack trace, and current stack to aid in debugging.

Containerizing Hardware Accelerated ApplicationsDocker, Inc.
Many applications allow you to use hardware such as GPUs and FPGAs for acceleration. Common examples include media processing and offloading highly parallel work to a GPU. Applications that use accelerators are resource heavy and have stacks spanning kernel and user space; accelerators often have their own requirements for operating system support and kernel versions. While it may not seem intuitive to containerize this type of application, the use of containers provides benefits such as reduced setup time from container reuse, reduction in dependency conflicts and dependency on a specific operating system, and easier updates.
In this session I show a media processing stack, making use of containers alongside a GPU. Specifically, I explain the kernel and user space divide of a hardware-accelerated transcode application using a device exposed to the container. This specific stack is an interesting case because of its dependency on hardware, use of a custom kernel and libraries, and operating system requirements. Our investigations have shown the use of containers has minimal performance overhead compared to running natively. Furthermore, we can quickly deploy on other machines with reduced configuration effort. There are some aspects of the application not suited to containerization, however. Since the application relies on a custom kernel, the use of containers does not necessarily increase portability. Improvement in this area would require rethinking how the applications are developed and distributed. Other areas of innovation include things such as Docker plugins to check for compatibility between the container software and host kernel.
The document discusses Agnostic Device Drivers (ADD), a concept for a slimline boot firmware for Linux on Power Architecture systems. ADD uses a small virtual machine to execute bytecode programs that control low-bandwidth devices like I2C and GPIO in a platform-agnostic way.

Conversational agents, or chatbots, are increasingly used to access all sorts of services using natural language. While open-domain chatbots - like ChatGPT - can converse on any topic, task-oriented chatbots - the focus of this paper - are designed for specific tasks, like booking a flight, obtaining customer support, or setting an appointment. Like any other software, task-oriented chatbots need to be properly tested, usually by defining and executing test scenarios (i.e., sequences of user-chatbot interactions). However, there is currently a lack of methods to quantify the completeness and strength of such test scenarios, which can lead to low-quality tests, and hence to buggy chatbots.
To fill this gap, we propose adapting mutation testing (MuT) for task-oriented chatbots. To this end, we introduce a set of mutation operators that emulate faults in chatbot designs, an architecture that enables MuT on chatbots built using heterogeneous technologies, and a practical realisation as an Eclipse plugin. Moreover, we evaluate the applicability, effectiveness and efficiency of our approach on open-source chatbots, with promising results.

Dandelion Hashtable: beyond billion requests per second on a commodity serverAntonios Katsarakis
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).
