QNX Enhances Performance of Network Elements with Big Endian Support for Intel® XScaleTM Technology-based Processors

OTTAWA, April 29, 2003 - In its latest step to optimize the QNX® Neutrino® RTOS for wireless and wireline networking equipment, QNX Software Systems has announced Big Endian support for processors based on Intel XScale technology.

"Endian" refers to how a computer system stores data: most significant byte first (Big Endian) or least significant byte first (Little Endian). By supporting Big Endian - the byte order used by most networking software - QNX Neutrino allows net-centric applications such as routing and packet processing to run faster, with less marshaling overhead. Big Endian support also makes it much easier for networking OEMs to port their existing stacks and applications to systems based on Intel XScale technology.

"Networking vendors are under pressure to reduce risk and maximize return on investment," said Sachin Lawande, director, product management, QNX Software Systems. "With QNX Neutrino's Big Endian support, they can migrate to a variety of Intel XScale technology-based processors while leveraging their existing code base. The time and cost of porting is kept to a minimum."

Intel XScale technology-based processors that will benefit from QNX's Big Endian support include the Intel IXC1100 control plane processor as well as the Intel IXP2400, Intel IXP2800, Intel IXP2850, and Intel IXP4XX network processors.

"Networking OEMs are taking advantage of the high-speed line rates, low power consumption, and application flexibility of Intel's XScale technology-based processors," said Jim Finnegan, general manager of the Intel Network Processor Division. "QNX Neutrino's Big Endian support and POSIX-based memory-protected architecture provide its customers with a smooth migration path to the Intel IXC1100 control plane processor and the IXP2XXX/IXP4XX network processors."

QNX will add its Big Endian support for Intel XScale technology-based processors to QNX Momentics® Professional Edition, a fully integrated development suite that includes the QNX Neutrino RTOS; a graphical IDE; tools for C, C++, and Java development; and a host of board support packages, libraries, and driver source kits.

QNX's Big Endian support will also work with other ARM-based processors compatible with the QNX Neutrino RTOS.
