Anthony Murray, senior vice president of CSR Business Unit, said: “Car owners expect to be able to safely control all aspects of the driving process with just one click, whether it is music playback, communication or tire pressure monitoring, interior lighting. The challenge to achieve this is With a number of ready-to-use in-vehicle solutions for a wide range of connectivity functions, CSR has been actively working with automakers to develop CSRatlas7 and tuneX solutions with its years of experience in automotive connectivity, positioning and in-vehicle entertainment information systems. Delivering greater configuration power and flexibility to the industry. CSR also offers a range of integrated platforms that enable secure, seamless collaboration with other automotive features, helping to reduce bill of materials and speed time-to-market."
CSRatlas7 platform for in-vehicle entertainment information systems
As a new member of the mature CSR in-vehicle SoC product line, CSRatlas7 was originally designed to meet the needs of today's connected consumer groups for complex entertainment information systems. The application processor features a dual-core CPU and GPU architecture and is equipped with a variety of integrated peripherals including Bluetooth®, Software Defined Radio (SDR), GNSS baseband, audio digital signal processor (DSP) and high quality audio codec components.
CSRatlas7 offers a range of advanced entertainment information system features that enable consumers to access a large-scale ecosystem of new in-vehicle entertainment information systems and navigation applications through sound systems for a highly sensitive and seamless in-car experience. For example, high-quality wireless audio streaming is provided by integrating the widely used CSR aptX® audio codec; to ensure high reliability of navigation, CSR SiRFDrive® technology is used to provide higher positioning accuracy. For assisted smartphone navigation applications.
The software and hardware solution is equipped with a large number of differentiated software stacks, including: CarPlayTM and MirrorlinkTM for multimedia transmission between external devices and in-vehicle entertainment information systems; cVc® for hands-free devices to output high-quality calls; An SDR solution for the tuneX® front end that supports all radio technology standards worldwide. In addition, the chipset integrates an approved software package to help entertainment information system solution providers dramatically reduce complexity.
Jeff Jury, chief operating officer of iBiquity Digital and developer of AM/FM audio and data broadcasting HD RadioTM technology, said: "We are delighted that CSR can be a member of our HD radio partner family, and CSR is the leader in automotive solutions. Vendors. With the growing popularity of HD radio technology, integrated solutions like the CSR Atlas7 platform will ensure that consumers get the ultimate in-car entertainment information experience in the new cars they buy."
New tuneX pin compatible front-end tuner chip
Anthony Murray, senior vice president of CSR Business Unit, said: "The tuneX series products can be 'regionalized' and differentiated with a single global hardware platform, providing OEMs with higher configuration capabilities, flexibility and portability. And provide consumers with future-oriented radio broadcasts. This combination of hardware and SDR software makes tuneX perfect for car radios, audio and video systems, entertainment information systems, receiver boxes and smart antenna applications."
The tuneX pin-compatible front-end tuner chip delivers leading-edge RF performance and supports all radio standards such as AM/FM, DAB, T-DMB, DRM and HD RadioTM, eliminating the need for OEMs to develop proprietary hardware for each region.
Car radios currently on the market use multiple digital broadcast standards based on geographical differences and must be localized. With the tuneX solution, regionalization and differentiation can be done in the software unit; at the same time, although the processing is performed in the SoC's RAM and flash memory system, the demodulation is transferred from the hardware unit to the software unit for execution. There is therefore no need to configure a dedicated car radio processor. This further simplifies the development, certification, and procurement processes, enabling OEMs to introduce differentiated radio products and adjust performance parameters in time for front-end development, thereby reducing the cost of SDR car radio products.
The tuneX companion software provides OEMs with greater flexibility to adjust performance, upgrade new features or patches for new services, and add more features in the future to provide consumers with upgradeable software and highly configurable A car radio for the future.
Another advantage of tuneX is that it supports synchronous signal reception and is scalable when it is converted from a single tuner to multiple tuner concepts. When the user chooses to switch to another radio channel, tuneX will make full use of the system memory. Once the dual tuner or combined tuner scheme receives two or more radio broadcast standards simultaneously, the received signal is stored in the software audio buffer, and the user can immediately fuse the various channel signals and output audio without significant delay.
The tuneX front-end chip or tuneX software demodulator can be purchased as a single item or in conjunction with a fully integrated radio package installed on the newly launched CSRatlas7TM platform. It can also be used as a collaboration solution for third-party platforms.
