Everyone remembers their first car, since you have it, you can go where you want, go faster, farther away. Yes, our car makes us mobile, but today's car itself is becoming a mobile device. Now the car is not just a means of transport, it is evolving into Sensor a mature mobile device, it can connect to the Internet, traffic network, and connect with each other. The MIPI specification plays an important role in this transformation, just as they play an important role in the interface of smartphones.
The purpose of the MIPI alliance is to make the connection between systems in mobile phones and other devices easier and more economical. The interface specification defined by the organization standardizes the interface of cameras, displays and wireless modules, making the data transfer between high-speed processors, low-speed sensors, and other chips-to-chip. Mobile devices are usually very small, and the components deep inside the device are connected together in a very compact manner. The transformation of the car into a networked device Temperature Sensor is also realized from the inside to the outside, so it is well suited to take advantage of the work already done within the MIPI Consortium. Suppliers of smartphone system interfaces can apply these developments to the automotive industry. The ability of suppliers (using the MIPI specification) to create efficient power and performance interfaces provides the same benefits to companies in the automotive supply chain that provide similar interfaces to mobile handset manufacturers and their suppliers. The car system is being wired and wirelessly connected together. This connection is becoming the 'central nervous system' of the car. The MIPI specification provides a growing number of mission-critical systems, connectivity between information systems and entertainment systems, to turn cars into a mobile device. Telematics requires the Global Positioning System (GPS) to be connected to a navigation display that includes touch and sound functions. Driving assistance requires camera, radar, laser radar, image processing and computer vision systems to be connected with audio and display for direct feedback.
The intelligent transportation system requires wireless access to the connection of the vehicle to the infrastructure (V2I), the car to the car (V2V) and the car to everything (V2X), and bridges the radio frequency (RF) function to support a number of different wireless (IEEE 802.11p , ac, ah, bluetooth) and cellular (LTE, GSM) standards. With the gradual realization of automatic driving, all of these systems and their interconnection will become more important. In smartphones, there is a similar interaction between cameras Speed Sensor and displays, audio, microphones, gyroscopes, magneto-optical components, and applications that require touch or voice activation input. The MIPI specification for the efficient definition of these interfaces for smartphones also applies to interfaces developed to support these systems in the car. Today these specifications are being deployed.
Mixel's D-PHY Rx + not only follows the MIPI D-PHY specification, but also adds this important customization option. The MIPI Union-defined specification allows optimization in the implementation process. In this way, customers and suppliers can work with pin-limited constraints and system data rate delivery requirements and optimize power consumption, efficiency, and testability in this example. Safety and reliability, operational reliability and robustness are essential requirements for the components used in the vehicle. Because ADAS functionality is mission-critical, it makes our driving safer, so safety standards are important. But even non-critical systems must work reliably over a wide range, and often in harsh environmental conditions. Validation design requires the use of statistical simulations that incorporate aging effects and temperature changes. Mixel changes the key parameters in the normal allocation of running simulations, thus taking into account each device change. The design goal is to be implemented within Six Sigma. This simulation requires Throttle Position Sensor careful planning so that the performance within the D-PHY's working environment is predictable. Performance is further validated by Mixel and NXP with extended testing and completed characterization. Additional efforts to achieve a reliable and safe system work.
Use MIPI in radar, laser radar and other equipment
The MIPI specification will continue to evolve and deploy to the right place as suppliers extend the ADAS extension to the autopilot field. Radar (millimeter-wave radio) and laser radar (ray) sensor subsystems also require the transfer of large amounts of data. These systems can use the MIPI interface to transfer data from the connected analog front end to the ADC / baseband and signal processing components or directly to the system-level fusion processing system and start the appropriate action there. In applications such as adaptive cruise control, the MIPI CSI-2 interface perfectly connects the RF front end to a radar processor (such as NXP's S32R27, which uses the Mixel MIPI D-PHY to connect to NXP's MR3003 RF front end Device). Here you need to analyze the continuous burst of transmission in order to detect the target, to determine the car to the car relative speed, the final adjustment speed. These are high-bandwidth data transfers, and multiple arrays of analog-to-digital converters (ADCs) support data collected from long and short distances.
Regardless of whether the sensor uses line of sight or light, the MIPI interface will continue to be deployed in automotive sensor modules that support these critical data transfers. We are getting closer to the fast, safe, informative Pressure Switch and entertaining and less stressful driving target. Our cars will be equipped with more systems that require the MIPI Alliance's performance and power optimization interface.
