NEC Electronics introduced the EC-4260 (NaviEngine-MID) and EC-4250 (NaviEngine-mini) system-on-chips (SoCs) for use in automotive infotainment systems. The EC-4260 and EC-4250 devices have the performance, peripheral set, and software ecosystem to meet the demands of high-performance applications such as navigation, infotainment and telematics systems. The EC-4260 and EC-4250 are currently available for samples, priced per unit at US$140 and US$70 respectively. Mass production is estimated to begin in 2010 and is expected to reach 100,000 units per month by 2012.
The EC-4260 with three CPU cores and EC-4250 with two CPU cores are ideal for car-navigation systems, particularly in Japan, Europe and the U.S. The EC-4260 and EC-4250 are the first members of NEC Electronics’ new EMMA Car series of automotive system LSI devices. Using three ARM-11 cores, the EC-4260 SoC operates at 1440 MIPS (at 400 MHz), while the EC-4250 performs 960 MIPS using two ARM-11 cores.
Basing these devices on an industry-standard core gives design engineers access to a wide array of software elements, which will both shorten design time and lower software development costs. The multi-core architecture also supports symmetrical multi-processing (SMP) mode. In this mode, a single version of the operating system (OS) is running on multiple cores, and tasks are dynamically allocated to cores at runtime, maximizing the utilization of available processing power.
NEC Electronics’ new devices also include a graphics processing unit (GPU) that realizes excellent 2D/3D imaging. The EC-4260 SoC enables 2D/3D imaging and supports OpenGL ES and OpenVG specifications. The EC-4250 enables 2D imaging and supports the OpenVG specification. These features provide graphics software compatibility contributing to faster time-to market for system designers.
The new products also have a comprehensive development environment for serving the needs of automotive customers. For example, for communications, there is support for a variety of protocols, including USB, MOST bus, CAN, I2S and I2C. Also included is an audio routing engine that has sample rate conversion capability. Rounding out this offering is a suite of software to support quick development, including evaluation boards, in-circuit emulator, on-chip debugger, middleware, and operating systems, all of them also compatible with those of the EC-4270 SoC. NEC Electronics will collaborate with partner companies to provide full-featured development tools to support designers to facilitate shorter development cycles.
