8- And 16-Bit Microprocessors Gain TCP/IP Stack
Today's networked devices require TCP/IP. Compact Internet device designers can take advantage of low-cost processors with CMX-MicroNet TCP/IP stacks and TCP/IP-based applications from CMX Systems. ROM requirements start at 3 kbytes. Ethernet, dial-up and direct connections are supported. CMX-MicroNet is written in C with source provided. Standalone and RTOS versions are available. You can acquire the software for a one-time fee with no royalties.

Voice-Activation Toolkit Simplifies
Speaker-Independent Recognition Using C
Voice activation can provide hands-free operation of embedded devices. Sensory's Voice Extreme Toolkit makes programming the company's RSC-364 speech chip in C a snap. Speaker-independent and speaker-dependent voice recognition with speech prompting, speech verification, and audio record and playback are supported.
The RSC-364 incorporates microphone input and preamp plus DSP, amplifier, and speaker output. Available for $2.40 ($3.85 in large quantities), it supports Sensory Speech 5.0 Technology. The Voice Extreme Toolkit, which includes development hardware with an RSC-364 chip, sells for $129.

Real-Time UML Developers Gain Testing Tool
Testing real-time Unified Modeling Language (UML) designs is not an easy task. The latest version of Rational Software's real-time UML development environment, Rational Rose RealTime, has a new test tool option, Rational Test RealTime. Features include object testing of new components, UML sequence diagram tracing, and hard real-time system testing support with millisecond-timing resolution. It also handles Rational ClearCase and ClearCase LT, Rational's change management tool.
The latest version of Rational Test RealTime now incorporates Rational Quality Architect for RealTime and new support for Sun's Java 2 Micro Edition (J2ME) platform and Mobile Information Device Profile (MIDP). Both features are included in the price of Rational RoseReal Time. Rational Test RealTime will cost $5495 per node-locked license and $9625 per floating license.

TCP/IP Stack Offloads Host For Gigabit Speeds
Gigabit Ethernet pushes most processors to the limit, so offloading network processing to an intelligent network interface card (iNIC) can increase performance and reduce processor overhead. Wind River's Tornado for Intelligent Network Acceleration (TINA) architecture and software streamlines iNIC and processor integration. TINA initially supports Intel's XScale microarchitecture and Wind River's VxWorks 5.4 RTOS. Wind River's reference board is based on Intel's 80200 processor.
TINA splits the TCP/IP stack across the host processor and the XScale processor. It supports hardware-assisted checksum generation and hardware-assisted segmentation. The stack supports Jumbo frames. Because TINA handles the OpenNIC API, developers can write customized applications, such as virtual private networks and firewalls. Linux host drivers are included as well. TINA can support iSCSI, sending SCSI commands over TCP/IP. The application development kit is available now.
