The solution, developed in collaboration with Freescale Semiconductor and Consilient Technologies, consists of a Freescale Kinetis K60 microcontroller based on ARM Cortex M4 technology combined with an audio subsystem specifically designed for voice communication. The microcontroller is preloaded with VoIP and Mbarx-M2M (machine-to-machine) middleware which runs on the MCU's internal flash and SRAM with no need for a co-processor or additional memory components. The solution is available as development kit, a production board, a module or a pre-programmed MCU.
"An MCU-based solution achieves a simpler overall design, better system integration, a lower cost bill-of-materials and reduces boot time," said David Steele, product manager. "By enhancing the VoIP capability with our Mbarx-M2M stack we can voice-enable 'Internet of Things' applications including home control and multi-service intercoms, two-way voice security applications and healthcare devices for assisted living."
The voice middleware includes a full SIP/RTP VoIP stack using peer-to-peer or PBX/proxy infrastructure modes with additional firmware supporting multicast IP audio distribution and mass-notification. Audio encoding supports narrow-band (G.711a, G.711u) and wide-band (G.722) vocoders along with the necessary audio intelligibility and psychoacoustic enhancements to support full-duplex, handsfree intercoms and speakerphones including; Acoustic Echo Cancellation (AEC), noise reduction, Auto-Gain-Control (AGC) and optionally, beam forming and far field microphone pickup. The system is low-power and ready to place a call in under 6 seconds from a cold start -- suitable for remote or solar powered call boxes or other "wake on demand" applications.
The system is operated using a dedicated I/O interface or over-the-wire using the Mbarx-M2M protocol. Dedicated I/O directly support common push-to-call functions, features and status notification, while offering integration options to connect legacy or external equipment. The Mbarx-M2M protocol supports configuration and operation over a network or serial interface, including a network-to-UART pass-through mode that allows a remote host to address a connected serial device over the network. This flexible mix of peripheral, host and slave options, simplifies system-level integration for IoT applications and highly supervised workflow systems.
"Freescale's Kinetis K60 32-bit MCU is powerful enough to run two-way real-time voice communications as well as M2M control signaling, providing small-form-factor, highly-integrated VoIP solutions," said Freecale's Rudan Bettelheim, Business Development manager for Freescale's MCU business . "Today, voice is becoming an increasingly popular HMI option in traditional building security, public safety, home control, and residential security applications."
Access to an eco-system of Mbarx-M2M tools is provided with the kit, including the Mbarx-System Manager for site-wide maintenance and configuration, and the Mbarx-Virtual Control Panel, a host-side reference implementation designed to help with using and integrating the protocol.
All run-time software is preinstalled on the MCU, there is no costly NRE, complex BSP to install or expensive tools to buy.
