Abstract: At a microphone, voice activity is detected in a data stream while simultaneously buffering audio data from the data stream to create buffered data. A signal is sent to a host indicating the positive detection of voice activity in the data stream. When an external clock signal is received from the host, the internal operation of the microphone is synchronized with the external clock signal. Buffered data stream is selectively sent through a first path, the first path including a buffer having a buffer delay time representing the time the first data stream takes to move through the buffer. The data stream is continuously sent through a second path as a real time data stream, the second path not including the buffer, the real time data stream beginning with the extended buffer data at a given instant in time. The buffered data stream and the real time data stream are multiplexed onto a single data line and transmitting the multiplexed data stream to the host.

Abstract: A plurality of sensors are coupled to a data transmission bus and a command line. A marker is transmitted across the command transmission line. The marker is sensed at each of the plurality of the sensors. At each of the plurality of sensors, data is transmitted over the data bus at a predetermined time from the marker. Each predetermined time for each of the plurality of sensors is different from the predetermined time at the other sensors. Data transmitted from each of the plurality of sensors does not interfere with data transmitted from others of the plurality of sensors.
