Cores to power next-generation WLAN chipsets
Wireless LAN chipset specialist Atheros Communications has licensed both the ARM926EJ-S and ARM946E-S processors.
The VeriCall Edge platform enables developers to add VoIP functionality without the need for costly and power-hungry external VoIP ASICs or digital signal processors (DSPs).
VeriCall Edge technology uses the available computing power within the ARM926EJ-S microprocessor core with DSP extensions to introduce soft VoIP functionality into the equipment.
"The VeriCall Edge platform and the ARM926EJ-S processor combination is a compelling approach for OEMs to implement the most cost sensitive VoIP SOHO devices", said Mike Inglis, Executive Vice President of Marketing at ARM.

"Furthermore, the single chip VoIP subsystem solution significantly reduces development cost, design complexity, and time-to-market".
"Developers of VoIP residential gateways, ATAs, and IP phones now have a significant advantage in significantly reducing bill of material costs", said Salim Bhatia, CEO of Trinity Convergence.
"Not only does the solution eliminate the need for a costly DSP, but the highly portable nature of the VeriCall Edge platform enables OEMs to leverage the price, power, and performance curves of any semiconductor vendor employing the ARM9E core family".
The ARM9E family enables single core solutions for microcontroller, DSP, and Java applications, offering savings in chip area and complexity, power consumption, and time-to-market.
The ARM9E family of products are DSP-enhanced 32bit RISC processors, well suited for applications requiring a mix of DSP and microcontroller performance.
The family includes the ARM926EJ-S processor, the ARM946E-S processor, the ARM966E-S processor, and the newly released ARM968E-S processor, optimised for low-cost information and networking applications.
They include signal processing extensions to enhance 16bit fixed point performance using a single-cycle 32 x 16 multiply-accumulate (MAC) unit, and implement the 16bit Thumb instruction set giving excellent code density, maximising savings on system cost.
The ARM926EJ-S processor also includes ARM Jazelle technology which enables the direct execution of Java bytecodes in hardware.
The VeriCall Edge platform includes the principal VoIP functions with a flexible framework including: G.711, G.726, G.729 A/B, GSM/AMR, EVRC and SMV voice coders, voice activity detect, packet loss concealment, acoustic and line echo cancellers, DTMF detect and generate, jitter buffer manager, RTP/RTCP/UDP/IP, and an embedded SIP stack for call control on a single chip solution.
The VeriCall Edge platform is written in portable C.
Optimised versions are available for the ARM9E family of products.
The initial release of the VeriCall Edge platform will be under embedded Linux.
Future releases will support VxWorks, Symbian OS and Microsoft CE.NET.
