Embodiment Construction

[0036] The present invention is further illustrated by way of examples, but will not be limited to the scope of the embodiments.

[0037] In view of the problems present in the background, this embodiment provides a Zynq-based main chip, such as figure 1 As shown, including the PS (Processing System, Processing System), and PL (Programmable Logic, Programmable Logic), where the PL is provided with a sound controller and an I2S (Inter-IC Sound, an integrated circuit built-in audio bus) converter.

[0038] The sound controller is configured to receive sound data in accordance with the AXI (Advanced Extensible Interface, a bus protocol) bus interface, and transmit the sound data in parallel to the I2S converter.

[0039] The I2S converter is configured to receive parallel data output by the sound controller, and convert the parallel data into serial data that conforms to the I2S protocol, and outputs the serial data to the outside.

[0040] In the specific practical application scen...

Abstract

The invention provides a master chip based on ZYNQ, ADAS and a method for utilizing the ADAS to conduct voice prompt. The master chip based on the ZYNQ comprises a processing system (PS) and a programmable logic (PL), wherein the PL is internally provided with a voice controller and an I2S converter; the voice controller is used for receiving voice data in accordance with the interface form of an AXI bus, and transmitting the voice data to the I2S converter in a parallel mode; the I2S converter is used for receiving the parallel data output by the voice controller, converting the parallel data into serial data in accordance with an I2S protocol and outputting the serial data to the external. Compared with the prior art, by utilizing the master chip, voice prompt for different road conditions can be achieved without requirement of adopting a special audio converting chip, and therefore the circuit structure is simplified, the cost is decreased, and meanwhile the stability is improved.

Description

Technical field [0001] The present invention relates to the driving assistance field, and more particularly to a main chip based on Zynq (Xilinx, Xilinx, Xilinx, Xilinx, which is launched by Xilinx, which is launched by Xilinx. The method of voice prompt is performed using the advanced driving assistance system. Background technique [0002] ADAS is the use of a wide range of sensors installed in the car in the first time to collect environmental data in front of the car, the treatment of static, dynamic objects, detection and tracking, etc., so that the driver can make the driver in the most Available in the hazardous truth in a fast time to attract and increase security technologies. The sensors used by the ADAS system mainly include radar, laser, and ultrasonic waves, etc., which can detect light, heat, pressure, or other variables used to monitor car state. [0003] The function of the ADAS system voice prompt road condition and the danger alarm is very important during the d...
