PLX SDK v3.5 Features up to 42-X Improvement in API Performance; Full Support for Linux 2.4 Kernels, Windows XP

10/15/2002 - PLX Technology, the leading supplier of high-speed interconnect silicon to the communications industry, announced the newest PLX® SDK Pro v3.5 software development kit (SDK), which dramatically boosts performance - up to 42 times that of the previous SDK — in Linux and Microsoft® Windows® XP drivers for all PLX I/O Accelerator devices.

The SDK v3.5 includes major enhancements to PLX's PCI drivers; many of the SDK's advanced programming interface elements have been optimized to take advantage of the drivers' performance in Linux and Windows. SDK v3.5 benchmark testing conducted by PLX shows API performance at near 51MB/s under Windows, and 45MB/s under Linux, representing a 4200 percent improvement over the SDK's predecessor. Additionally, the SDK adds support for Linux kernel 2.4, the latest for that operating system.

"Developing systems and boards with PLX's PCI devices running under Linux and Windows continues to demand more speed from the API libraries," said Tom Martin, product marketing manager at PLX. "In addition to adding support for the latest Linux kernels, the SDK v3.5's APIs have been optimized to significantly increase the performance of user designs. Designers of communications and other embedded systems can use PLX's array of proven development tools, now featuring the SDK v3.5, to take full advantage of PLX's PCI device performance in a variety of today's operating environments."

The SDK Pro v3.5 is tailored to the needs of the software engineer, facilitating the development of application code for use in proven platforms, such as Linux and Windows XP. The SDK includes local-side, real-time operating systems (RTOS) application API libraries, drivers and board support packages that accelerate the development of real-time software running on PCI-based systems and adapters.

Additionally, the SDK Pro v3.5 provides host-side support, consisting of Windows and Linux host drivers, APIs and libraries, enabling developers to rapidly establish communication with PLX I/O Accelerator devices across the PCI bus. (A Windows host-side-only version of the kit, the SDK-LITE, also provides the same Windows drivers, APIs and libraries as the SDK Pro v3.5.) With the SDK Pro v3.5's broad operating-system and PCI silicon support, developers can write host- and local-side software for any PLX PCI I/O Accelerator device.
