&& PREVIOUS FINALIST | MAIN | NEXT FINALIST >> Category: Embedded-system Technologies Finalist: AYRE wireless platform, Sound Design Technologies Sound Design Technologies’ AYRE (SA3410) hybrid is an ultra-low power and compact wireless platform targeting body-worn designs. It consists of a DSP SoC, nonvolatile memory, and a wireless transceiver. The DSP SoC is Sound Design’s programmable multicore WOLVERINE platform that includes two ADC’s, one DAC, five cores, and 573kbits of on-board memory. The nonvolatile memory consists of up to 1 Mbit of EEPROM and 256kbit of one-time-programmable memory. The wireless transceiver is a proprietary Near-Field Magnetic Induction (NFMI) device capable of delivering 298 kbps of data up to 55 cm without any external boost circuit. When programmed to stream 20 kHz of audio and with the DSP running adaptive noise reduction, adaptive feedback cancellation, adaptive directional microphone, and environmental classification algorithms, the AYRETM hybrid consumes under 4 mA of current when operating off a 1.2V battery. The innovative aspect of the AYRE hybrid is the level of integration achieved in a small footprint using Sound Design’s thinSTAX packaging technology. The device contains three integrated circuits, 15 capacitors, a resistor, and a diode in a compact size of 6.35 x 3.68 x 1.65mm. The only external components required to implement a wireless receiver are a battery, an antenna, switches, and a speaker. Add one or two microphones and the system is capable of implementing a noise cancelling ear-bud. |
