ARM Introduces DSP ‘Lab-in-a-Box’ For Education Combining STMicro STM32F4-Discovery Board and Wolfson Audio Card

DSP (Digital Signal Processing) courses at University have traditionally used software simulation packages (Matlab), or hands-on labs using development kits costing around $300 per student. In order to reduce costs, ARM University program and their corporate partners have launched a DSP ‘Lab-in-a-Box’ so that university students can learn DSP and audio systems with hardware selling for about $50, or over 80% cheaper than previous educational hardware. A typical DSP Lab-in-a-Box (LiB) would come with: STMicroelectronics ARM Cortex-M4-based STM32F4 Discovery MCU board Wolfson Microelectronics and Farnell element14 Wolfson Audio Card. ARM Keil MDK-Professional development tool with a 1-year renewable software license. Teaching materials such as lecture slides, code samples, and hands-on lab manuals. STM32F4-Discovery board features an STM32F407VGT6 MCU (ARM Cortex-M4F core) with 1 MB Flash, and 192 KB RAM, sensors (motion and accelerometer), a digital microphone, and audio DAC, a micro USB connector, and various buttons and LEDs. The Wolfson Audio Card bring HD Audio, at 24-bit, 192KHz via audio …

TI TMS320C6748 DSP Low Cost Development Kit for Fingerprint Recognition and Face Detection

Texas Instruments recently introduced the TMS320C6748 DSP development kit (LCDK) for real-time analytics applications such as fingerprint recognition and face detection, as well as other digital signal processing applications, such as audio and communications. The C6748 DSP development kit comes pre-loaded with TI C6748 SYS/BIOS Software Development Kit (SDK) which includes: SYS/BIOS real-time kernel C6748 StarterWare software package (lightweight, operating-system-independent software libraries and utilities) Sample apps for fingerprint recognition and face detection Code Generation Tools DSP core performance benchmarks that show the real-time processing power of TI’s C674x DSPs. The C6748 DSP development kit also includes Code Composer Studio IDE v5.1. Several standard interfaces for connectivity and storage are available in the board to allow audio, video and other signals. Expansion headers also allow developers to add display and user interface technology, such as camera boards and LCD screens. The board schematics and design files are supposedly available for download, although I could not find where… and very little information …

Linux 3.3 Release

Linux Torvalds announced the release of Linux Kernel 3.3 on the 18th of March: So after the extra -rc release last weekend, now the final 3.3 is out there in the usual locations. Things did indeed calm down during the last week, and the shortlog looks pretty boring. The diffstat from -rc7 is dominated by the arch/tile defconfig changes, the rest is pretty small, although there are changes spread out in various subsystems (drivers, filesystem, networking, perf tools). … And obviously, the 3.3 release means that the merge window for 3.4 is now open, although I may keep of pulling stuff for a day or so to encourage people to test the actual release. Linux 3.2 brought ext-4 and btrfs file system improvements, support for Qualcomm Hexagon processor, an improved profiling tool (perf top), and better CPU and network bandwidth management. Linux 3.3 brings the following key changes: Android merge: As announced at the end of last year, the Android …

Embedded Systems Outlook and Trends for 2012

National Instruments has recently published a report entitled “Embedded Systems Outlook 2012 – Key Technologies and Methodologies Impacting the Embedded Systems Market” which lists technology and business trends for the development of embedded systems. Here are the key findings: Technologies & Architectures: Embedded Platforms Technology providers are developing components, modules, or even complete embedded platforms (software + hardware) with higher levels of integration and increased functionality to speed up time to market. System-on-Chip (SoC) and System-on-Module (SoM) benefit from this trend and some also embed a FPGA. Reconfigurable Computing Previously, designers chose between low-cost microcontroller or high performance CPU based on the expected performance needs of the embedded system. As cost decreases and performance increases, low cost devices such as control and monitoring systems now often come with more features thanks to the use of programmable logic. This type of flexibility can be achieved by adding an FPGA to the MCU / MPU in the embedded systems platform. Mobile Devices and …
