Abstract: A signal decode circuit is coupled to a buffer for each signal channel. A memory includes a shared area configured to store waveform data sets, each waveform data set including a sequence of coded waveform values specifying waveform step states. The shared area further stores delay data sets, each delay data set including a digital delay value for each signal channel defining a delay profile. A signal pointer addresses the shared area to read one waveform data set from the memory with the sequence of coded waveform values being selectively loaded into one or more of the buffers. A delay pointer addresses the shared area to read one delay data set from the memory with the digital delay values used to control delayed actuation of the signal decode circuits to decode the sequence of coded waveform values from the buffers and generate waveform signals in accordance with the delay profile.

Abstract: A memory includes a sequence of memory locations storing a corresponding sequence of state codes that specifying the shape of a waveform. The sequence of state codes is read from the memory and decoded by a long and toggle decoder circuit. The decoding operation generates a sequence of signal codes. When the state code is a long code, the sequence of signal codes includes same signal codes corresponding to a signal level of the waveform. When the state code is a toggle code, the sequence of signal codes includes a first signal code corresponding to one signal level of the waveform and a second signal code corresponding to another signal level of the waveform. A signal decode circuit then decodes the signal codes in the sequence of signal codes to generate the waveform for output which includes the signal levels corresponding to the decoded signal codes.

Abstract: A waveform generator includes a system control unit and signal channels controlled by the system control unit and configured to supply driving signals for driving a respective transducer of an array of transducers. Each signal channel includes a sequential access memory having rows, where each row contains an instruction word configured to generate a respective step of a waveform to be generated. A memory output of the sequential access memory is defined by an output row at a fixed location. The waveform to be generated is defined by a block of instruction words. Each signal channel also includes an internal control unit that is configured to sequentially move the content of the sequential access memory, based on the instruction word currently at the memory output, so that sequences of instruction words are provided at the output row.

Abstract: A digital representation of a waveform is generated based on signals received during a recording period. The received signals include a digital clock signal providing a determined number of clock pulses during the recording period, a plurality of binary digital signals defining, for each clock pulse of the determined number of clock pulses, a waveform state associated with the clock pulse. A digital representation of the waveform is generated and stored. The waveform has a duration based on the recording period and a profile based on the defined waveform states associated with the clock pulses of the determined number of clock pulses.

The control unit may cyclically control the acoustic transducers in a transmission state for transmitting ultrasound signals, and in a reception state for receiving echoes of the transmitted ultrasound signals. The control unit may include an input stage which receives an external timing signal, and a processing stage which detects a first edge of the timing signal to determine the start time of a transmission phase during which the acoustic transducers are controlled in the transmission state, and a second edge of the timing signal to determine the stop time of a reception phase during which the acoustic transducers are controlled in the reception state.
