NEC Electronics has unveiled NaviEngine1, said to be the industry's most powerful single-chip system LSI solution optimized for car navigation systems.

Based on four high-speed CPU cores using the ARM MPCore technology with symmetric multiprocessing (SMP), NaviEngine1 can simultaneously process multiple streams of information needed for car navigation systems, including vehicle location, driving directions and navigation functions. The chip delivers high-speed parallel processing performance of up to 1,920Mips at 400MHz.

Key features
The NaviEngine1 integrates several major features.

Using four ARM11TM MPCore multicore processors co-developed with ARM, with processing speeds of 480Mips each (at 400MHz), NaviEngine is the world's first single-chip solution designed for car navigation systems with SMP capabilities. At minimal power consumption levels, it can reach a maximum of 1,920Mips, enabling multiple screen images such as routes, one-segment broadcast reception and road conditions to be displayed simultaneously via the car navigation system.

According to NEC Electronics, NaviEngine1 is about three times more advanced than existing graphics systems used in car navigation systems. It includes a POWERVR SGX 535 graphics core by Imagination Technologies with pixel processing of up to 13 megapolygons per second, enabling 2-D, 2.5-D (bird's-eye view) and 3-D images using only a single chip.

NaviEngine1 is also claimed to be the world's first chip for car navigation systems to include a serial ATA interface, which is essential for high-speed access to large volumes of data (such as required for maps and navigation). Moreover, the integrated LCD controller is designed to display several images simultaneously, assuring smooth map scrolling and user-friendly interfaces.

To provide a development environment for customers, NEC Electronics has collaborated with numerous companies to provide assessment reports, in-circuit emulators, debuggers, middleware as well as OS support. For example, the eT-Kernel Multi-Core Edition by eSOL is an RTOS that has a direct drop-in support for the NaviEngine platform. System developers interested in faster time to market can easily utilize such software coupled with development tools and middleware from partner companies to reduce the costs associated with application software development.

Samples of NaviEngine1 are available now, priced at $90. Volume production is scheduled to begin in March 2009.
