Internet processor
The
Au1000 Internet Edge processor
is based on the MIPS instruction set and is designed for high-performance at low-power. It runs at speeds of up to 500MHz. Its peripheral set targets communications market segments whose products operate on the 3outer edge2 of the Internet network, such as wireless palm-sized PCs, third-generation data devices, VoIP telephony devices, firewalls, and routers. The Au1001s architecture consists of a 32-bit core and includes a five-stage scalar pipeline, 16K instruction
cache, a 16K non-blocking data cache, a high-speed multiply-accumulate (MAC) unit and an R400 class memory management unit (MMU). Its peripherals include 10/100 Ethernet controllers, fast IrDA, multiple UARTs, AC 97 controller, and I2S.

Client software
EmWeb/Client
is software that allows devices to initiate basic HTTP transactions (GET, PUT, and POST) with any web server on the Internet for communications such as the transmission of new configuration files or firmware images, notification of web-based alarms, and distribution of configuration information to other networked devices. It supports persistent connections (meaning it reuses TCP connections, rather than
establishing them each time a URL is to be fetched). Used in conjunction with EmWeb/Server, EmWeb/Client can implement applications through send and receive communications between different devices and web-based applications. The idea is that were you to have a networked printer attached to the Internet by means of a unique web page address, it would be possible to automatically upload a document residing on a different web page to the networked printer.

Information Linux
Based on Red Hat Linux,
NeoLinux
is an OS designed for business-to-business information appliances such as cash registers, firewalls, routers, interactive web-kiosks, thin clients, security devices, and wireless
appliances. Its features include ezCompress, which allows Linux to be installed on small systems without a hard drive; ezOFF, which allows people to turn off their device without going through the 3shut down2 process required by a desktop OS; ezSecure, which makes the OS read only; and ezManage, which allows appliances to be remotely managed, configured, and updated across a LAN or WAN. NeoLinux is designed to operate on Intel X86 or compatible processors.

Tools for Bluetooth
The
Bluetooth Extension to WinDK
is a toolkit that enables developers to attach Bluetooth hardware to a tested Windows Bluetooth stack. It may be used to develop hardware and protocol drivers for Bluetooth
implementations based on the Digianswer A/S Bluetooth software stack. Also featured by the Bluetooth Extension to WinDK is support for the development of hardware drivers for USB, PCI, and PCMCIA buses, as well as serial interfaces. Additionally, it lets you access the hardware using any combination of port I/O, memory I/O, interrupts, and DMA. It1s available now for $14,995.

Design kit
Micro WebTarget
is a hardware/software prototyping technology designed for Web-enabled cell-phones, PDAs, pagers, and other mobile devices. It1s based on the connected limited device configuration component (CLDC) of the Java 2 platform, Micro Edition. The Micro WebTarget features a single processor core from Hyperstone
Electronics that combines a 32-bit RISC processor with a 16-/32-bit DSP unit. The processor core provides 200 MOPS of processing power at 50MHz. Also included is a built-in Ethernet controller and interface transformer support for a direct network connection. In addition to 4MB of DRAM and 1MB flash, the MicroWebTarget utilizes HyNetOS, a real-time network operating system designed specifically for the Hyperstone RISC/DSP architecture. The MicroWebTarget is available now for $2,350.
