System-On-Chip for Car audio system by NEC
NEC Electronics one of the industry leaders in the area of automotive electronics and in particular the automotive infotainment solution has unveiled their latest product a SoC (System-On-Chip) targeted at car audio systems. The µPD35502 with capability of increasing the processing of audio data provides a playback functionality of multiple songs, multiple sources and multiple destinations allowing the flexibility of playing different songs at the front and rear seat of vehicle. Essentially this multi source decoding capability will enable the development of systems where the driver and the front and rear seat passenger can each enjoy different music at the same time. NEC offers a complete software package which includes compressed audio decoding software (Codecs) for MP3, WMA and AAC as well as other audio decoding standards. The µPD35502 is further allows upgrades of system such as human machine interface (HMI) as well as adding new audio Codecs. The product includes built-in USB and SD card interfaces for playback of audio data through portable music player, USB memory devices and SD cards. The product also has several serial communication channels for inter chip transfer of audio data. The µPD35502 comes with optional support for Bluetooth wireless technology allowing system development for hand free calling and wireless music transfer functionality. The product is currently available for sampling and the mass production is expected to begin in September of this year.

[...] NEC Electronics made an announcement on development of new system-on-chips (SoCs), the EC-4260 (NaviEngine-MID) and EC-4250 (NaviEngine-mini) targeted to be implemented into automotive infotainment systems. The new systems were designed to meet the performance, peripheral set and software ecosystem which is demanded by high-performance application s such as navigation, infotainment and telematics systems. The new EC-4260 three ARM-11 base CPU cores operates at 1440 MIPS at 400 MHz, while the EC-4250 performs 960 MIPS using only two ARM-11 cores. The multi CPU core architecture in the new systems support symmetrical multi-processing (SMP) mode whereby single version of operating system is running on multiple cores and tasks are dynamically allocated to cores at runtime resulting in maximum utilization of available processing power. The new devices also come with a graphic processing unit (GPU) capable of 2D/3D imaging, supporting OPenGL ES and OpenVG specifications. Furthermore, the new devices support variety of protocols such as USB,MOST, bus, CAN, I2S and I2C. The new devices also include an audio routing engine which features sample rate conversion capability. As pat of the suite of software in supporting quick development are evaluation boards, in-circuit emulator, on-chip debugger, middleware, and operating systems. Both EC-4260 and EC-4250 devices are available for samples at a price per unit of US$140 and US$70 respectively. Company’s mass production is estimated to begin in 2010 with an expected 100,000 units per month by 2012. Share and Enjoy: [...]
