The SH-Navi3 is a dual-core SoC built around a pair of SH-4A CPUs for superior processing performance of up to 1920 MIPS (when operating at 533 MHz).
It integrates graphics and image recognition processing functions that have been tweaked for improved performance.

Dual DDR3-SDRAM interfaces, which support simultaneous access, and a PCI Express interface enable ultra-high-speed data transfer. The many on-chip peripheral functions also include a serial ATA interface, allowing increased easy-to-use in car information terminal applications.
