Toshiba and Hellosoft Demonstrate Low-Cost, DSP-Free VoIP Phone

Aug 07, 2004

HelloSoft, Inc., a leading provider of communication intellectual property and Toshiba America Electronic Components, Inc. (TAEC), a leader in high-technology products, today announced the development of a complete voice over Internet Protocol (VoIP) phone software suite fully optimized for the Toshiba T6TC1XB-001 embedded controller. The T6TC1XB-001 is built on a single ARM926EJ-S™ processor core. The software reference design implementing the phone suite includes complex voice algorithms and protocols running on the embedded Linux operating system (OS) and can be seen at the HelloSoft booth, booth 105, at the VoIP Developer Conference in San Jose, August 3 - 4.

The TAEC and HelloSoft solution implements all VoIP functions, including codecs, line echo cancellers, acoustic echo cancellers, telephony components, and telephony signalling stack, on the Toshiba T6TC1XB-001-based reference design. The reference design is built on a single ARM926EJ-S processor core running the embedded Linux OS.

"The TAEC and HelloSoft solution represents a step forward in assisting original equipment and original device manufacturers in significantly reducing the cost and complexity of developing VoIP phone systems," said Richard Tobias, vice president of the ASIC and Foundry business unit, TAEC. "The optimized solution is powerful enough to implement two channels of voice for VoIP phones, wireless IP phones, residential gateways, integrated access devices and other VoIP-enabled devices."

"The Toshiba T6TC1XB-001 embedded controller-based design together with HelloSoft's expertise in utilizing RISC processors efficiently for complex DSP algorithms enabled us to develop this high-performance, ultra low-cost VoIP solution," said Krishna Yarlagadda, CEO and president, HelloSoft. "This low-cost VoIP solution from our two companies cannot be underestimated in regards to its effect on enabling the market."

The HelloVoice™ software suite on the Toshiba reference design is an enhanced solution including G.711, G.726, G.723.1 and G.729AB vocoders, G.168-2000 Line Echo Canceller, Voice Activity Detection (VAD), Comfort Noise Generation (CNG), Jitter Buffer, Packet Loss Concealment (PLC), DTMF Tone Detection and Generation, Call Progressive Tone (CPT), SIP/RTP/RTCP Call Signalling and Control, and multi-channel system-level framework.

The T6TC1XB-001 embedded controller is part of the Toshiba SoCMosaic™ custom chip program that lowers development costs and enables tape-out in as little as six months using mix-and-match IP blocks and a standardized bus. The T6TC1XB-001 embedded controller runs at 150MHz, and features two full-duplex Ethernet 10/100 Media Access Controllers (MAC), an ARM926EJ-S core, 2 x 16KB cache, 8KB Static Random Access Memory (SRAM), Memory Management Unit (MMU), Real-Time Clock (RTC), counter, interrupt controller, Universal Asynchronous Receiver Transmitter (UART), watchdog timer, General Purpose Input/Output (GPIO), 33MHz Peripheral Component Interconnect (PCI), static and non-volatile memory (flash/SRAM/ROM) interface controller, Synchronous Dynamic Random Access Memory (SDRAM) controller, Direct Memory Access (DMA) and Joint Test Action Group (JTAG) /Scan /BIST.

Pricing and Availability
Voice components and protocols are available now from HelloSoft. The Toshiba T6TC1XB-0001 embedded controller and its reference design are available now from TAEC and is priced at $13.50 each in 1,000-piece quantities.
