ChipWrights Marks Major Milestone with First Linux® Software Release

June 22, 2009

Bedford, MA, June 5, 2009. ChipWrights, Inc. - part of AD Group – announced the availability of its media browser software for the CW5631 processor. The software provides the components to build a multimedia product that runs under the Linux operating system on a CW5631 processor target platform.

By leveraging the Linux open source environment with the processing power and feature-rich peripheral set in the CW5631 processor, developers can quickly release applications such as IPTVs, IP set-top boxes, personal media players (PMP), and digital signage and networked video applications.

“ChipWrights is delivering on its promise to advance the CW5631 development platform into a cross-platform environment,” said Halil Padir, Director of Software at ChipWrights, Inc., a semiconductor company based in Bedford, Massachusetts. “Our customers can take advantage of Linux’s open source environment to easily develop applications or port existing applications that run on Linux to the CW5631 processor,” he added. This reduces time to market considerably.

The software is based on a Linux 2.6.24 kernel, which provides the device drivers for the CW5631 interfaces: Ethernet, USB 2.0, IDE, MMC/SD, CompactFlash (CF), Video out (NTSC/PAL composite and VGA), OSD, Audio (I2S), I2C, SPI, GPIO, LIRC, UART, 802.11 wireless, and DSP. The Linux kernel runs on an ARM926EJ-S® core with DSP acceleration. The DSP provides acceleration for codecs and various image processing functions.

Media browser is a simple application that provides Internet access and is based on Qt™ libraries. Qt provides a cross-platform application development framework for the development of GUI programs. Mplayer provides media player functionality. Simple Direct Media Layer (SDL) is a cross-platform multimedia library designed to provide low level access to audio, keyboard, mouse, joystick, and 2D video framebuffer, which is what Mplayer uses to display videos through the framebuffer driver. Modern, low bandwidth codec support includes H.264, MPEG4, MPEG2, MJPEG, JPEG, AAC, MP3, and G.711. The software also supports ChipWrights' Hardware Development Kit, IPTV, and C1IPB reference designs.
