| Avago Technologies Introduces IrSimple Protocol Software Avago Technologies has announced the release of its IrSimple protocol software, a new global IrDA standard for camera phones, digital cameras and other mobile devices incorporating IrDA infrared communications hardware. Avago's ASDL-S900 IrSimple protocol software can be implemented alone or coexist with existing IrDA protocol standards. The IrSimple protocol improves IrDA transfer throughput as compared to existing IrDA protocols for large files, including high-resolution JPEG picture files, MP3 and WMA music files and AVI, WMV and 3G video files. It is able to achieve a throughput as high as 90 percent. For example, at the 4 Mbps FIR (fast infrared) data rate, existing IrDA protocol might achieve a data transfer rate of 2 Mbps, whereas the IrSimple protocol would attain up to 3.6 Mbps. With IrSimple, users can quickly and easily ("point and shoot") transmit images from a camera phone, PDA or digital still camera to a color photo printer or a television for immediate viewing. Users can also enjoy fast data transmission between two mobile devices. IrSimple allows business travelers to make slide presentations directly from their PDAs or smart phones to infrared-equipped projectors, eliminating the need for notebook PCs and associated cables. Avago's IrSimple solution has been tested and verified at all standard speeds. It supports SIR (serial infrared, 115 Kbps), MIR (medium infrared, 1.152 Mbps), FIR (fast infrared, 4 Mbps), and VFIR (very fast infrared, 16 Mbps). It also supports UFIR (ultra fast infrared, 100 Mbps) and a frame size of up to 32 KB. Avago's IrSimple Protocol can be implemented in a wide variety of consumer devices because it supports both bidirectional and unidirectional profiles. To use IrSimple with existing IrDA protocols, Avago offers its HSDL-S101 IrOBEX (infrared object exchange) v. 1.3 and HSDL-S100 IrDA protocol stack, which have been installed in numerous mobile devices. Avago supplies the ASDL-S900 IrSimple source code in standard ANSI-C programming language, making it portable to a variety of platforms. write your comments about the article :: © 2006 Computing News :: home page |
