Vim Touch: Vim Editor for Android

Many Linux developers or admins use vi or vim in Linux to edit source or/and configuration files and some may want to use it in the go in their smartphone or tablets. Some hacks are available to install vim on Android via ADB on a rooted device, but now, it has all become nice and easy, as a touch enabled version of vim called VimTouch is also available on Android. VimTouch supports full vim syntax and finger touch gestures to help VIM much more usable on touch screens. This vim editor for Android includes the following features: Touch to scroll Fling to scroll Long press to zoom-in Two-fingers to delete lines (“dd”) or new lines (“p”) Single tap to send “ESC” Read email attachments Single instance to open files in vim window Real VIM runtime You would think it is rather cumbersome to use vi/vim on a mobile device, but reviews […]

ARM Development Studio 5 (DS 5) Demos At Design West

ARM has shot a few video demos of their ARM Development Studio 5 (DS 5), a software development tool suite for ARM platforms, at Design West 2012. The first video shows DS 5 running on the Xilinx Zynq-7000 platform (dual cortex A9 + FPGA), and we can see the memory map, registers, call graphs and stack usage. We can also see real-time processor switching and the function that takes the most CPU resources (profiling). The second videos showcases ARM DS-5 Streamline, a performance analyzer, which helps determine how well programs are running on a Linux or Android platform, on an Samsung Exynos 4210 platform (Origen board?). This tool also to profile both the dual-core ARM Cortex-A9 and ARM Mali-400 MP GPU in the platform. We are shown three types of reports: CPU/GPU Loading Threads usage Power Usage per application The third and last video shows ARM DS 5 on Freescale i.MX6 […]

Express Logic Releases ThreadX-Lite RTOS for ARM Cortex-M

express_logic_threadx

Express Logic has unveiled its ThreadX-Lite Real-Time Operating System, a priority-based, preemptive scheduling RTOS for ARM Cortex-M development. It is exclusively be available via IAR Systems and is integrated with the C/C++ compiler and debugger tool suite IAR Embedded Workbench. ThreadX-Lite  is “designed to be small, fast, and easy-to-use, while maintaining the functionality and efficiency of a highly optimized RTOS”. ThreadX-Lite targets Cortex-M0, M0+, M3, and M4-based microcontrollers from Atmel, Freescale, Fujitsu, Infineon, NXP, STMicroelectronics, and Texas Instruments. ThreadX-Lite is a subset of ThreadX RTOS, both RTOS share features and capabilities packaged in an object library as well as ThreadX API, but it is not very clear what the differences between the two are from the resources available. Here are the key feature of this RTOS: Small-footprint (small as 2KB, automatic scaling) Fast execution (sub microsecond context switch) Unlimited threads, semaphores, timers, queues, block pools, byte pools, and event flag groups […]

Linaro 12.03 Release with Kernel 3.3-rc3

Linaro has just released version 12.03 based on Linux Kernel 3.3-rc3 and Android 4.0.3. Among the key points, hardware video decode in now supported in Origen (Android),  Android runs in A15/A7 platforms, libav AAC optimization provides about 2x performance improvement and QEMU supports Samsung Exynos 4240 and Calxeda Highbank (work done upstream). Here are the highlights of the release: Android Linaro Android has support for DS-5 version 5.9. Hardware accelerated Multimedia is now integrated on Origen. EEMBC, denbench and coremark have been ported to Android and are running in LAVA. android.net ConnectivityManager unit tests have been built and integrated in all builds. Hardware decode of H264 and MPEG4, 1080P and 30 FPS is enabled on Origen. Origen now has 1080p HDMI Graphics and Video Support. Android runs on A15, A7 and A15/A7 fast models. ARM’s big.LITTLE has been tested running Android using a set of unit tests. Kernels of prebuilt […]

Xilinx Zynq-7000 Extensible Processing Platform (EPP): Dual Cortex A9 + FPGA SoC

The Xilinx Zynq-7000 EPP (Extensible Processing Platform) is a new class of device, offering a mix of a dual-core ARM Cortex-A9 subsystem (including cache, memory controllers, interface, and peripheral functions) with a 28-nm programmable digital FPGA and programmable analog capabilities. This  combination opens the door to a range of demanding applications, including automotive (video processing and analytics requirements for driver assistance systems), broadcast (high-bit-rate bandwidth for high-accuracy video processing and analytics), and industrial control systems that combine high-processing demands with tight integration requirements. There are actually 4 models which share the same processing subsystem (CPU core, memory, peripherals, etc…) and only differ by the programmable logic used: Z-7010 – Artix-7 FPGA with 28K logic cells. Z-7020 – Artix-7 FPGA with 85K logic cells. Z-7030 – Kintex-7 FPGA with 125K logic cells. Z-7045 – Kintex-7 FPGA with 350K logic cells. The Zynq-7000 EPP platform allows concurrent software and hardware development: System […]

ARM Releases Ne10: An Open Source Library with NEON Optimized Functions

Arm NE10

The Advanced SIMD extension (aka NEON or “MPE” Media Processing Engine) is a combined 64- and 128-bit single instruction multiple data (SIMD) instruction set that provides standardized acceleration for media and signal processing applications for ARM Cortex-A (ARMv7) processors and the goal of these instructions is similar to MMX, SSE, and 3DNow! extensions for x86 processors. Starting early 2011, ARM has been working internally on a project codenamed Snappy to develop common functions accelerated by NEON. They have now released the first version of Snappy, now called the Ne10 library, which is available on GitHub at https://github.com/projectNe10/Ne10 . The code has been developed in C and Assembler and tested on Ubuntu on ARM (Linaro). A Makefile is also included to build it for Android (AOSP). The current functions include vector and matrix operations accelerated by NEON instructions. Since the library is open source, ARM hopes developers will make use of the Ne10 […]

Virtual Hardware Platforms: Test & Debug Software Before the Silicon is Ready

Historically software could only be tested and debugged when the first silicon sample was ready, and the software team could not participate in the design process. But thanks to Virtual Hardware Platforms, software can be executed at speeds close to real time on an abstract model of the hardware, available long before a design has been completed. The virtual platform is designed to simplify the creation and support of virtual prototypes and allow design teams to begin developing software weeks to months before a hardware prototype is available, and software teams can use it as their application development platform. For example, Freescale is using a Virtual Hardware Platform for their new Vybrid Controllers to emulate both Cortex A5 and Cortex M4 cores, as well as peripherals and run OS such as Linux or MQX before the Controllers are ready (Q2 2012). One Virtual Hardware Platform has just won the ACE […]
