Green Hills has the lot for Cirrus Crystal
The latest IDE, RTOS and embedded internet connectivity products from Green Hills Software are for the Cirrus Logic Crystal CS89712 32bit RISC commmunications processor.
In addition, the reference hardware can be used for rapid software development and testing prior to the availability of a product's final electronics.
"Green Hills Software's new Wi-Fi reference platform takes much of the time and risk out of the development of Wi-Fi-enabled products", said Dan Mender, Director of Business Development for Green Hills Software.
"It lets developers start with a working system from day one".

Compiler exploits PowerPC vector coprocessor
Green Hills Software has a new compiler for its Multi IDE that provides automatic vectorisation support for Motorola PowerPC processors equipped with the AltiVec vector-processing engine.
"We deliver all of the software and hardware integrated, including the 802.11 device driver, security protocols, networking stack, embedded operating system, and software development tools".
The Green Hills Wi-Fi reference platform addresses a broad range of applications, from resource-constrained mobile devices through mission-critical network infrastructure equipment.
Accordingly, it can be configured to use Green Hills Software's ultracompact or advanced routing TCP/IP stacks, both of which are available in IPv4 or dual-mode IPv4/IPv6 configurations.
It can also be used with either of Green Hills Software's royalty-free embedded operating systems: the small and fast Velosity microkernel for resource-constrained and cost-sensitive devices, or the memory-protected Integrity real-time operating system for devices with high security and protection requirements.
Scalability and flexibility between TCP/IP stacks and real-time operating systems allows developers to reuse application code across projects and product generations.
The initial release of Green Hills Software's Wi-Fi reference platform uses an Intel XScale processor and Conexant Prism 802.11a/b/g chipset.
A software-only Wi-Fi solution is also available for users who choose to integrate with their own custom hardware platforms.
Green Hills Software's Wi-Fi driver and dual-mode IPv4/IPv6 networking stacks are developed by technology partner Interpeak.
"Interpeak's advanced Wi-Fi, IPv4 and IPv6 security support, coupled with the Integrity RTOS, delivers the industry's most secure and reliable Wi-Fi platform", commented Johan Fornaeus, Chief Executive Officer of Interpeak.
All the latest Wi-Fi security mechanisms will be available for the Green Hills Software reference platform, including: Wired Equivalent Privacy (WEP); Wi-Fi Protected Access with Pre-Shared Keys (WPA-PSK); and IEEE 802.1x Extensible Authentication Protocol (EAP), including Transport Level Security (EAP-TLS), Protected Extensible Authentication Protocol (PEAP), and MD5 authentication.
These Wi-Fi security protocols complement the IP security solutions available today for Green Hills Software's stacks, including IPv6/IPsec, Internet Key Exchange (IKE), Secure Sockets Layer (SSL), Secure Shell (SSH), Firewall, Crypto and more.
When used with the Integrity real-time operating system (RTOS), the Green Hills Software Wi-Fi solution provides the maximum possible level of security for the end platform.
The Integrity RTOS allows a system to be divided into multiple partitions, each with a guaranteed allotment of memory and processor time.
This prevents a task running in one partition from carrying out a denial-of-service attack on another partition, and ensures that high priority and real-time tasks can continue to run regardless of what else is going on in a system.
In addition, hardware memory protection is used to prevent a task in one partition from spying on or corrupting a task in another partition or the operating system itself, thereby protecting against hackers and maliciously inserted code.
The Wi-Fi software solution with WEP and WPA-PSK is available now for ARM, Blackfin, Coldfire, MIPS, PowerPC and x86 processors. Request a free brochure from Green Hills Software ...
