Jungo Software Technologies, a provider of residential gateway software platforms and applications, will soon introduce a newer version of its WinDriver, a software development toolkit that enables developers to create custom device drivers that can run on a multitude of OSs without modification.

"The new version will be an interim version between the presently latest available version, WinDriver 5.2, and WinDriver 6.0, planned to be introduced globally in March 2003," said Roy Tannenbaum, the product manager at Jungo.

The WinDriver 5.2, which was introduced in September 2002, has new features such as the WDM, plug-and-play and power management. According to Erica Narcyz, Marcom manager for Jungo, "WDM has emerged as the standard by which plug-and-play and power management for Windows OS is implemented. Jungo tools now enable writing drivers which employ full spectrum of WDM capabilities."

This version also enables 64-bit data transfer. "High data transfer capability enables the WinDriver to utilize the additional bandwidth provided by 64-bit hardware on x86 platforms running 32-bit OSs," explained Tannenbaum. "Drivers developed using the WinDriver are expected to attain significantly better performance results than drivers written with DDK or other driver development tools that do not have this feature."

With WinDriver 5.2, Jungo's driver tools are enabled to provide enhanced support for the PLX PCI 9656 I/O Accelerator chip. "The tools include a special set of APIs for PLX's 64-bit silicon, which implements PCI 9656 access and control," said Tannenbaum. "A sample PCI 9656 application is included and can be used as a skeletal driver to further jumpstart driver development. The PCI 9656 I/O Accelerator is the industry's first bus-mastering silicon to enable 64-bit, 66MHz operation in adapters and embedded hosts that incorporate Motorola PowerQUICC processors or generic 32-bit, 66MHz local bus designs. The PCI 9656 serves designs that demand maximum PCI bandwidth without incurring the expense or effort of implementing 64-bit peripherals on the local bus."

Further, Narcyz stated that WinDriver also eases driver distribution. "Drivers developed with WinDriver require installation of only one kernel module on target computers," she said. "An enhanced utility enables smooth and easy installation and removal of drivers on both customers' target computers. Moreover, in one mouse click, WinDriver automates INF installation, eliminating the multiple steps involved in the end user's exposure to Windows' "Found New Hardware" wizard. These features, in addition to the enhanced driver generation wizard, provide an even better user experience and a rapid development cycle for device drivers and hardware access applications."

Other enhancements of 5.2 include API support for multiple interface USB devices, dual processor, and SMP support on Linux and scatter/gather DMA support on Linux 2.4.

The next version, which is scheduled to come out around January 2003, is expected to further enhance the abilities of WinDriver 5.2. Tannenbaum said, "The most important enhancements over 5.2 version would be WinCE.NET support, Microsoft's latest CE OS; and USB for Linux, thus enabling USB customers to enjoy cross platform capability. WinDriver USB for Linux will also enable customers to port code for USB drivers developed for Windows OS with WinDriver to Linux without having to rewrite the code, and vice versa, that is, customers that develop drivers for USB hardware running Linux will be able to port the drivers to Windows OSs."

According to Narcyz, the market for Jungo products is equally divided between Asia, Europe, and the U.S. "We look forward to even larger markets in Japan and Taiwan upon the launching of our new products," she said.
