DETROIT—Derek McAulay is one hardy Scotsman. The Cadence principal design engineer had just landed from his trans-Atlantic flight when he dived right into a technology demo here at the IEEE Standards Association’s Ethernet & IP @ Automotive Technology Day event.
McAulay showed an automotive audio solution that pulled out-of-sync audio signals back in sync for two speakers. Using Cadence IP including an Ethernet mac, a Tensilica Xtensa processor and an Integrated Interchip Sound (I2S) module, he showed the automotive solution in an audio unit using automotive Ethernet using AVB packets. He demonstrated how to get the packets back in sync using the solution and leveraging precise time protocol standard (PTP).
