This application note describes a method for developing block-oriented I/O device drivers
for applications that use the DSP/BIOS real-time kernel and includes examples that run
with Code Composer Studio v2.1 on the Texas Instruments TMS320C5402 and
TMS320C6711 DSP Starter Kits (DSKs). The device driver model presented here has
now been superceded with an updated version that supports not only block oriented
DEVICES, but also DEVICES such as UARTs, PCI and USB buses and Multimedia cards.
Documentation on the updated driver model as well as example drivers and source code
can be found in the Device Driver Developer s Kit product now available for download
from the TI Developer s Village.

Need to play Windows Media files and streams, mpeg4 video or DVDs in java? Access WDM capture DEVICES? Control a firewire DVCam? Then maybe this can help you. dsj is an ongoing project to provide a java wrapper around Microsoft s DirectShow API. It offers a set of high level classes that give java easy access to functionality widely missed by java programmers and also lets you dive deeper into the interiors of Windows core api for 2D media. On the java side dsj tries to keep things open as possible - you may use it standalone or let it feed data into JMF or other APIs.
關于FPGA流水線設計的論文
This work investigates the use of very deep pipelines for
implementing circuits in FPGAs, where each pipeline
stage is limited to a single FPGA logic element (LE). The
architecture and VHDL design of a parameterized integer
array multiplier is presented and also an IEEE 754
compliant 32-bit floating-point multiplier. We show how to
write VHDL cells that implement such approach, and how
the array multiplier architecture was adapted. Synthesis
and simulation were performed for Altera Apex20KE
DEVICES, although the VHDL code should be portable to
other DEVICES. For this family, a 16 bit integer multiplier
achieves a frequency of 266MHz, while the floating point
unit reaches 235MHz, performing 235 MFLOPS in an
FPGA. Additional cells are inserted to synchronize data,
what imposes significant area penalties. This and other
considerations to apply the technique in real designs are
also addressed.
藍牙協議This specification describes the Audio/Video Control Transport Protocol (AVCTP), which is used to transport command and response messages for controlling Audio Video features in conformant DEVICES. This protocol enables a device to support more than one control profile at the same time each supported profile shall define its own message formatting and/or usage rules.
J2ME application that captures video from on-board camera of SymbianOS Series60 3rd ed. mobile DEVICES. A snapshot can be captured and image processed by manipulation of RBG pixels before displaying
goText is a program for mobile phones that allows you to send text messages over GPRS/EDGE/UMTS. It was made in Java (J2ME) MIDP 1.0 CLDC 1.0 and so avaible for all java mobile DEVICES.
這是一個Linux下的USB攝像頭捕捉程序，是一個調用V4L2（Video for Linux 2）非常好的例子。英文介紹為：This is a driver for the USB video bridge USBVision from Zoran/Nogatech, a USB-only cable used in many "webcam" DEVICES. It supports streaming and capture of color or monochrome video via the Video4Linux API. Most V4L apps are compatible with it, but a few video-conferencing programs do not work yet.

PeerSec Networks MatrixSSL?is an embedded SSL implementation designed for small footprint applications and DEVICES. PeerSec Networks offers a fully supported, commercial version as well as an open source version that is available for download. PeerSec MatrixSSL allows secure management of remote DEVICES. Several secure embedded Web servers also use MatrixSSL for their encryption layer.
This article describes Atmel’s FingerChip technology for electronic fingerprint sensing that
combines the advantages of small size, low cost, high accuracy, zero maintenance, low energy
consumption and portability. This technology has applications in a wide range of fixed and
portable secured DEVICES including access control systems, cash terminals, public transport, PCs,
PDAs, Smart Card readers and motor vehicles. It can be used in almost any situation where
rapid, reliable and accurate identification or authentication of an individual is required.
