BANGALORE, India Indian wireless startup Impulsesoft has signed deals with Broadcom Corp. and Silicon Wave Inc. to jointly develop hardware and software solutions for Bluetooth wireless applications.
Under terms of the agreement with Broadcom (Irvine, Calif.), the partners will supply Bluetooth-based solutions for PC manufacturers that include Impulsesoft's BluePC software stack and Broadcom's all-CMOS Blutonium silicon transceivers, for use in Windows PCs.
The partners said the deal would permit faster delivery of embedded Bluetooth functionality to PC makers.
The deal with Silicon Wave (San Diego), meanwhile, melds the BluePC software with Silicon Wave's Bluetooth chip set. The company's radio modem and baseband will be configured to run with Impulsesoft's Bluetooth protocol stack in platforms using qualified components.
Impulsesoft's single-threaded software architecture will be combined with Broadcom's Bluetooth chip sets to speed OEMs' design process, said Scott Bibaud, Broadcom's director of Bluetooth marketing.
Impulsesoft's BluePC protocol stack architecture aims to give OEMs the option of customizing software for specific applications, along with flexible driver implementation. It operates as a Windows driver for network access and handles serial-port emulation for wireless applications over the Bluetooth medium.
Broadcom's Blutonium chips are designed to allow a variety of implementations in embedded PC applications. The chip sets consist of multiple version 1.1-compliant radios and basebands, all featuring low power consumption. They also provide a fractional-N interface optimized for use in mobile phones. Two standalone baseband chips include host-based and HCI-compliant architectures.
In the Silicon Wave deal, the partners said the hardware/software approach will allow equipment makers to add Bluetooth functionality to PC cards and Compact Flash cards, enabling PCs to interact with other Bluetooth devices.
Silicon Wave was the first company to receive Bluetooth specification version 1.1 qualification for its products, which support point-to-multipoint, master/slave switch, flow-control and low-power modes.
"Together we offer a solution that uses fully qualified hardware and software," said Jarvis Tou, vice president of marketing and business development at Silicon Wave. "[That] helps reduce the design, development and testing time, and therefore reduces costs for end users."
Impulsesoft chief executive K. Srikrishna said the deals are part of the Bangalore company's strategy to speed delivery of Bluetooth applications. The company said in March it would work with Infineon Technologies AG on Bluetooth functionality for PCs and embedded applications.
