NEC NaviEngine1 Multicore platform

The NEC NaviEngine1 Multicore platform is equipped with four ARM 11 multicore processors and processing speeds of 480MIPS each. The NaviEngine 1 is the most powerful single-chip solution designed specifically for car navigation systems. The SMP capabilities and high-speed parallel processing performance enable multiple screen images of routes, road conditions and addresses and advanced graphic systems enable viewing of the LCD screen in 2D, 2.5D and 3D.
