Second Release of Debian 6 for Raspberry Pi

As Raspberry Pi boards have started to ship this week, the Raspberry Pi foundation has also posted a new Debian 6.0 “squeeze” release to the downloads section of raspberrypi.org this week-end. This release contains several performance enhancements, including enabling the 128K system L2 cache for the first time, and first-cut ALSA drivers. Enabling the L2 cache will boost the ARM CPU performance, however, it may decrease the GPU performance. So this setup is ideal for headless server, but for other applications, for example a media player decoding 1080p30 videos, the performance might actually go down. This is still customizable, as the L2 cache can be enabled / disabled with enable_l2cache parameter in the config.txt file stored on the SD card. The ALSA drivers are here for audio support, so audio output might not have been supported in the first release (TBC), except if they used another type of audio drivers […]

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 […]

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 […]
